Video Transcript for Trailer Bearings Races Seals and Caps Rebuild

Speaker 1: Today we're going to take you through the rebuild process on a couple of hubs. We've got an idler hub, and here we've got a hub and drum assembly. Works with electric rigs, but this can also work for just standard discs, if you've got a disc brake style setup.Basically what we're going to show you is how to get all of the bearings out. How to remove the seal. How to remove the race's if they're damaged, then get them replaced in the proper manner. We'll show you how to use an easy loop hub, which we have here.The first thing we are going to need to do is, get the grease cap off the end.

It can have either a rubber plug in it like this one does, or it can be a solid metal cap.These are pressed fit in there, basically by tapping on them on the back side. To remove them, a deadbolt hammer is typically what we're going to use. We're just going to start tapping as we go around. You'll see a little separation start right here, and slowly it'll work it's way off.Now the next step's going to vary a little bit depending on your axle setup. Do you see this is going to have a keeper that goes around the nut.

And that prevents that from being backed off, or removed. A lot of times you'll have a castle nut, which will have just little tabs that stick off, and there will be a cotter pin that passes through it. Just depending on your application, you need to get the keeper for the nut off. This style we just kind of pry out. A cotter pin you would just remove of course.Once we have that off ...

We'll start to take off the nut here, and the washer that's in behind it. Now yours should look a whole lot more dirty than this. There should be a lot of grease packed in, and through the hub, this one's brand new. We thought it'd be nice to show you the components before the grease was on .. Of our washer that comes off.And then here we're going to have our outer bearing.

Continue to pull that. We're gonig to have our inner bearing here. That sits in the backside of the hub. And we didn't put it in yet, we will show you how to put it in. But a seal would typically be covering the backside here. We'll show you how to use a seal removal tool, or another tool. To get that pried up and out. To get an access to that inner bearing.Now for a drum style like this, that process for disassembly is going to be just the same. One thing to keep in mind if you're using a disc brake setup. You'll have to remove the caliper before the disc is going to come off.Now once we have the spindle exposed, as we said this is going to be really greasy. We want to get all the grease removed, and the first thing we'll do is inspect it. We want to make sure that it looks just like what we have here. Everything's nice and smooth. We don't see any kind of discoloration, or any marring on the metal. Indicating that our bearing's got hot.If you do have any of those symptoms, at this point it's time to replace those bearings. You don't want to repack them. Get new bearings, and put in there. You might have a bearing that's come apart in here. Another surface to ensure is in good condition, is where your seal is going to go. That helps seal all the grease inside of our hub. With a damaged or broken seal, that grease is going to seep out. Either out of the hub, or in this case into our brake assembly.Now if your axle has brakes, we're also going to check the disc. Make sure it doesn't have any issues, or your hub. And this is going to be a hub and drum assembly. The brakes are going to ride on this machine surface. You're going to check that for signs of excessive heat, discoloration, or cracking. And this is our magnet surface. We'll check that surface for the same issues.Now inside the hub regardless if it's a disc brake, it's a drum brake like this. Or just a standard idler style hub. You're going to have an outer race. Would be right here, it's a small tapered piece of metal your bearing sits in, and rotates on. That's basically the outer portion of the bearing.You have the same thing here on the backside. This is called the inner race. Now if those show any signs of wear, overheating, or cracking. Those are also something we'll need to replace, which we'll show you how to do in just a minute.Now, with your brake assembly exposed, if you do have electric brakes like we have here. It's a good idea to check all the components for wear, cracking, maybe missing pieces. Check your pad thickness to make sure those are in good shape. Basically if you have a non working brake assembly and you put everything back together, you're just going to have to take it apart and do it all over again to get back to the brake assembly. This gives you a really good option to be able to change them out.And most applications are going to use a four, or maybe a five bolt flange to hold them in place. And you'll just remove the lock nuts, or sometimes you'll have a hex nut with a lock washer. You want to remove those, and then simply slide your assembly off after you cut the wiring.The friction material itself should also be checked for any kinds of cracking, or overheating. If you have any grease inside the system at all, it's likely it's gotten on those pads. It's a good idea to get those changed. Now as far as the removal of the races go, it's going to be just the same whether we're using an idler style hub like we have here. A drum brake like we have here. You can basically see where the idler is, here in the middle of the hub. It's going to go all the way around there, and we just have this extra material here to provide our braking surface.Now if you're doing a disc brake style job again, it's going to be just the same here with the races living inside of the actual hub portion. You'll just have the discs there for the brakes to make contact. We're going to use this little bit smaller one, it's a little bit easier to manage to show you how to get these out. We've talked about where the races are. The outer here, the inner being closer to the inside, but on the backside of the race there's a little lip. That lip's meant to stick out just a little bit further than the hub, and provide us an area to put our tool on, and help to drive that out.If you look all the way through there on that inner race, you'll see that little lip that sticks out just from the hub slightly, and it gives us enough area to use our tool on. Now generally to remove these you're going to use a punch, similar to this. Some guys will use a screwdriver. Or a piece of pipe. If you have a piece of pipe that's small enough to fit inside of that diameter, you can take that down through and allow it to rest on that lip.Use our punch, and then just need a hammer. And we'll start working that out. We're going to tap all the way around. Kind of equally, and evenly apply the force to get it to come on out of the bottom for us.You can see now as it starts to come out there's going to be a little gap created between the hub and the race. And we can just keep going, bringing it on out. Then you can inspect the inside of the hub surface there. Make sure no damage or anything has occurred, and repeat that same process for the outer race if you plan on removing and replacing that one.Now in the outer flat edge, you can see we're going to have our tapered edge on this side. If we roll our race over to the flat side, typically there's going to be a manufacturers part number on there. That will help you identify which race it is, that you need to go back in your system. If those are rubbed off, worn off, if you can't read them. You can measure the outside, to outside diameter of the race here. It's a good idea to use a micrometer to get it exact.Now here's your basic micrometer. And again, the outside of the race is what we're going to need to measure. You want to go . I set the thickest point there. Looks like this one's going to be about 1.98. That's going to be the measurement you'll want to supply.Now while we've got this out, let's also look at the proper way to measure our bearing. Instead of the outside for the bearing, we need to measure the inside diameter. That's going to be pretty simple. Let's pull that out, find the largest measurement we can. Which here, looks like it's going to be 1.03. With that information, we'll be able to get the correct bearing, and the correct race, so they'll fit together properly and make a full bearing kit for us.Now here's the race, we're going to show you how to get this put back in. Basically just going to press fit inside of our hubs. We need to get it down on there. Kind of like that. And you'll have a couple options. A lot of times you're going to see do it yourself or at homer, just going to use a wooden block. Just place it on there. That's going to get you started, but at that point you'll struggle in getting it to go all the way down into it's seat.Now to take care of that problem, there are several seal drivers that are available. Seal and race drivers that are available out there on the market. It's designed to fit down inside of our race, inside of our hub and get it down there where it needs to go. This is part number ptw83020, has several different sizes, even if you have multiple trailers it's going to do the job.Now the side with the angle on it, is designed to fit down inside of our race. If we use the other side, that's going to be for driving your seal into place. Just want to hold it, and take it on in with your hammer. You'll see, you just want to insure that our race is all the way up against that line on the hub where it's supposed to mate to.Now when it comes time to pack your bearings you're going to have several different ways of doing this. You can just use your hand, is the traditional method. That's going to be the method probably reserved for the very occasional trailer work kind of situation. If you do it once or twice a year, probably get away with it that way.Next you would go to a, kind of a sandwich funnel style almost. If you look inside of there, you can see the bearing. It's located between the two pieces. Just use a grease gun. Start filling that with grease, and that's going to fill our bearing for us. And the third, with this one you're just going to place your bearing down and in. It should be pretty close to center. And then we've got our cone her that's going to go down and secure that.Now I think this style, wastes a little bit more grease than what this style will. This has a dust cap. You can see, you can keep your grease in there, put your dust cap on there and save it for later use. This will be if your going to do it every couple years. And this particular style would be if you're a more regular user.Let's start by showing you how to use a bearing packer. Similar to this. Again, we've just got our grease inaudible 00:11:07 here on the top. And then just slowly start to fill it. Now I like this style quite a bit. I think even regular users might enjoy it, because you can get a really quick visual look at that bearing. You're not going to have to overdo it, or have to much grease.You can kind of see in there now, we're starting to get grease to come out of it. Couple more pumps, we'll be good. You can see we've got grease coming out all the way around. Where all of our bearings are. Got a little bit of excess there. Just take that around the outside of it. And then we should be able to lift it off. And now you can see what we we're talking about. Just a little bit of excess there, that you're just going to wind up wasting.Now we'll take our bearing, we're going to place it right down in our race. And then we'll cap off the back with our seal. Right now our seal's going to fit in just like our race did. It's going to have a little bit of a pressure fit to it. Now very often in this situation, I see people using the four by four method. Kind of here, just placing that on and tapping it. As an option though, if you do have one of these. You can see that's designed to fit right on the top of the seal. And help drive it in.The biggest thing here is, just going to be getting it driven in squarely. You can see, this side's in a little bit further than this side. I'm going to start this side first. Now since we didn't have the opportunity to show you before, we're going to take a look at pulling a seal. Now this is a seal puller, we carry this on our website part number ptw1219. This is meant to hook underneath the seal. And then you kind of pull up on it, and just like our race you'll have to work all the way around that edge. Just bringing it out a little at a time.If you don't have that available. Another option would be a screwdriver. You just kind of get that under the seal, and turn it. And see, that'll allow you to also pop that out. We've taken care of our race. Our inner bearing. Our seal. The last component, before we put our hub back in place is going to be our outer bearing. Now with this bearing, I'll show you the hand packing method.This is definitely . Slightly dirtier method than the bearing packer. When we get grease on our hand we want to look at the larger side of the bearing. This is the smaller side. We have a larger side In between the inside and outside there's a gap. We can see our rollers in there. We want to grab that, and use that gap and shove grease inside of it. Now this is going to take a little bit, you want to work in the same spot until you get the grease pushed all the way through. We can see on the top there we've got a little bit starting to come through.And once we push it in the bottom, and you see it start coming out the of the top in those little drips, it's going to indicate that, that section's fully packed. Just need to work all the way around their outside edge now and do the same thing. Alright, once that's all the way around . The bearing will be ready for use.Now one more thing I like to do. We can see our inner bearing there, and our outer bearing. Well between the two, got a pretty big gap in there. If you'll take a . Pretty good amount of grease. We're just going to go all the way around. See how we can go all the way around the inside and just line that really well. The more grease we have in here, the less chance we have of any moisture getting in there, which can cause corrosion, rust, pitting. Pretty much things we do not like when it comes to bearings, races, and hubs.Put plenty of grease in there. And then this one does have the easy lube spindle, that'll even fill it in more. Now we can get our assembly slid on. I like to keep my thumbs on that outer bearing, just to prevent it from . inaudible 00:15:28 pushed off there. Now we can put on the original hardware that we removed, in taking off our hub the first time. In our case, we had our washer and our nut.Now most commonly you'll see pliers similar to this being used. We basically want to get that tightened down. Once it's fully tightened down you'll feel some resistance in the hub. We back it off just slightly. That'll give us a little bit more freedom of motion there. Something you don't want however . Is any movement in, or out on your hub. You want to be sure that everything is compressed, and you don't have what's called end play. Which would be the play in and out.Once we've got that set, then you'll put on whatever tight keeper yours came with. Get that put back in place. Now with an easy lube style hub, you're going to place your grease gun on the end, and then you can just fill the remainder of that hub up.Now for your typical applications, you're either going to have a solid cap, or a cap that'll have a rubber plug in it. A solid cap's going to be for an axle without the grease inaudible 00:16:51 here on the end. Goes on there. Just knock it on with your rubber mallet. Same with the one with the plug. Just gives you a removable area there, be able to cap that off.We'll show you how to put that on. Now as alternatives as well, a lot of times on boat trailers and marine kind of situations. You'll see a bearing buddy. This is going to apply a little bit of pressure on the grease, you'll fill it up. This kind of comes out just a little bit. That applies constant pressure on the grease to make sure we don't have any air, or anything like that. Then there is also an oil bath hub available. Now this is going to be for use with seals that are going to be designed specifically for oil bath use. You'll have to change that seal.We're using a double lip seal. There are also single lip seals available. Of course a double lip seal is going to give you just a little additional security. Keep that in mind when you order. But let's get this knocked on there now so you can see how that works. We just want to take the cap, we're going to center it. This is going to be very similar to what we did with the seal. And then just gently start tapping it around the outside. And it'll seep down on there for you.It's really going to be the same thing that you'll do with any of the end caps. Now with this side done, it's a good idea to take care of all the other hubs. Get them all on the same maintenance schedule. And as long as you'll periodically check the grease, take your trailer out for a trip occasionally. Just to keep everything lubricated. It should extend the life of these parts, and give us years of good service.

Got the bearings in and they work great. I ordered them to the wrong address and got ahold of someone in like 30 seconds to get the actual ups postal number to find it in the warehouse. Coulda been a nightmare but they hooked it up, not often is mishaps easy.

Perfect fit for my 6x12 dump trailer. Good price and fast shipping. Had 1 inner bearing damaged in box, appeared to be a shipping issue. etrailer replaced it immediately.

When I opened up the box I was shocked to see precision bearings and seals just dumped in a box with paper stuffed on top with no individual wrapping of parts. This box road on the back of a delivery truck for almost 1,200 miles with the parts bouncing in the box. Considering i had to put them on a 30K trailer, I am not impressed! I don’t think anything obvious was damaged but who knows what happened internal.

Etrailer has very good products, and is a great place to find parts for your trailer/camper. I have a good experience with their products. I would recommend them to anyone who needs parts, even sometimes parts that you can’t find anywhere else at very reasonable prices. I couldn’t give five stars because delivery on some orders Has come a little late.

I put these bearings on a 21 ft travel trailer. The original bearings were poorly greased and got too hot. With these bearings and a good quality grease these bearings never overheated even with driving in hilly terrain with frequent breaking. Definitely recommend!

I got the email notification that the package was delivered before I went to the mailbox.This digital age is amazing. And the delivery was a day ahead of promised. I haven't installed them yet but I would like to complement etrailer on the tech support. I have a 19 year old Tracker trailer. Every few years I replace bearings and always have a problem with finding correct parts, It seems the L68149 inner bearing uses 2 different races that are different in size. To make matters worse the existing inner race was not marked with the correct part number. L68111 instead of the correct L68110. I measured bearing sizes several times and was still not certain what was wrong. While chasing down what to order I found the answer in the etrailer FAQ page. Having the exact measurements for the parts really helped. I also found the perfect replacement for the damaged rubber part on the transom saver for the boat. Now when it warms up a few degrees I can get these installed and be ready to go fishing. Thanks, etrailer.

Want to help out the next customer looking for the bearing, cups, and seals for 2000-01 tracker trailstar trailer. 1st you have to dismantle one of the hubs and see what trailstar decided to put in there the day they built it. You will find the rear cups and seals are considered "Special for some reason". Not a problem for etrailer, they have them in stock and the quality is excellent and are exact replacements. The parts I had to order were cup L68110, cup L44610, seal 168233, bearing L68149 and bearing L44649. Oh yeah, customer service should get a 10 star review. I had an issue with shipping co. because of new driver in my area. Etrailer got all up in their business for me and I didn't have to do anything. Customer service also called me the next day to see if everything was delivered and satisfactory. We need more companys like etrailer.com . Excellent!!

Don't do what I did...spend 2 weeks trying to find the right parts locally, and end up trying to use a 67 Chevy seal on a 2002 boat trailer...it doesn't work. Just order the right stuff from etrailer.com and save yourself a lot of time, money, and hassle. If you just absolutely have to go the auto parts store, their brake cleaner is pretty handy for removing grease from the trailer parts without removing the paint.

I could not be happier, What a diiference to have not just good brakes, but great brakes. Plus, the install was so easy, all the hardware was a perfect fit, instructions were right on the money (btw, I'm a retired engineer from a nuclear plant and I wrote procedures, so I'm picky) Anyway, towed the boat 1,000 miles and what a reassuring feeling to know that the equipment is in good working order and does the job when called upon. I'm attaching a couple of pictures so you can see what I did. Thanks again, I will be using etrailer in the future anytime I need something, feel free to pass on my comments

  • Do Bearings Come in Different Sizes
    Bearings come in a lot of different sizes and often you will need two bearings of different sizes for one hub. We carry about 25 different bearings. You cannot modify a bearing to make it fit. Changing the shape or structure of the bearing will cause damage and the bearing will fail. You need to choose the correct bearings for your hub and spindle.

    When your purchase the # 84656uc3 hub/drum, the races are already installed in the hub bore, as you can see in the photo I produced. Races are fairly easy to remove, but can be difficult to install without the correct tool. This is why the races are typically pre-installed.

  • How Tight Are Bearings When Installing On Spindles
    Bearings will be pretty tight on the spindle when they are installed. They should not be so tight that you have to really pound on them to fit but they can require a little bit of effort to get them to slide onto the spindle. When installed there should be no play between the inner surface of the bearing and the spindle. If you are asking about the castle nut and how tight it should be, when installing you want to tighten the castle nut until it stops turning or is snug. Then look to...

If you are unable to find them, you would need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached to see exactly where you need to measure. I've also added a link to a...

  • Can an L68149 Bearing be Used to Replace an LM68149 Bearing
    I am not quite sure what the M stands for but the # L68149 bearing will be an exact replacement for your LM68149 bearing. The M used to be used but was dropped as it became irrelevant in the part number side of things.

  • How to Pick Out Hubs and Bearings for Trailer
    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub...

  • Ways to Identify Correct Replacement Wheel Bearings for 2000 Coleman Cheyenne Pop-Up
    There are a few ways to find out what set of bearings is used in your trailer hubs. One way (the best way) is to pull a hub and remove the bearings to find their part numbers. Another way is to find the camper's VIN and contact Coleman with it; there is a chance they might have this information even though the trailer is 18 years old. The only other way, which again requires removing a hub, is to precisely measure your spindle at the 3 points shown in the linked diagram (B, C and D) using...

  • Picking Out Replacement Bearings for Grand Design Imagine RV Travel Trailer

  • Replacement for NOK AD7128R Trailer Hub Seal
    In order to find the correct replacement grease/oil seal for a trailer hub you have a few options. The first would be to use a digital caliper and measure the spindle where the seal rides along with the hub. The second would be to measure the existing seal you have now. Please note, these measurements will need to be taken to the nearest thousandth of an inch. I have then attached a list of options below. Unfortunately, I am not able to cross-reference the part number of "AD7128R". I...

  • Will TruRyde Bearing # L68149 Work With Imported # L68111 Race
    The replacement parts for the TruRyde Bearing # L68149 and the TruRyde Race # L68111 use industry-standard numbers. While it is preferable to use matching parts made by the same company, as long as the numbers match up for the parts you want to use, there should be no problem. In this case, the 2 numbers do match up as being parts that are compatible. I also recommend that you replace the bearings and races at the same time. We do not recommend using a new bearing with an old race because...

  • How to Determine Capacity of Trailer Axle to Replace Springs
    It sounds like your bearings are likely # L68149 for the inner and # L44649 for the outer. The numbers can get pretty hard to read sometimes. You should measure the inner diameter of both to confirm. The measurements you should come up with are 1.378 inches for # L68149 and 1.063 inches for # L44649. If these are correct you likely have a 3,500 pound axle on your trailer. To find the correct replacement springs you'll also want to measure the length of the existing spring and find...

  • Correct Replacement Parts For A Trailer Bearing Replacement
    Because trailer wheel bearings are specific to the spindle that is installed on the axle, you will need to confirm the bearing size for a correct match. First you will need to safely support the trailer, remove the wheel and tire, remove the grease cap, remove the cotter pin and washer that secures the spindle nut, remove the spindle nut, and then you will be able to remove the hub from your trailer. Once the hub is removed you will be able to get the part numbers from the inner and outer...

  • Replacing Metal O-Ring That Fell Out of Trailer Hub When Repacking Bearings
    Sounds like you are referring to a bearing race. Since you mentioned the bearing number # L68149 I believe this might be the bearing you have. The matching race would then be the # L68111. If you can get me the bearing number you have I can pick you out what you need or you can select it on the filters of the page I attached and the correct race will be listed.

  • Troubleshooting Trailer Bearing Replacements that are Too Tight to Fit Spindle
    You do have the correct bearings with the # L44649 and # L68149. It sounds like your spindle needs to be cleaned up a bit so that your new bearings can fit. This is a very common problem since bearings fits very tight to spindles. Maybe take some fine grit sandpaper to your spindle to clean it up so that you new spindles can fit.

  • How to Protect Replacement Trailer Bearings for Long-Term Storage
    If you want to store replacement bearings for an extended period until you need them I recommend coating them with the same wheel bearing grease you will eventually pack into them, like # L11380, and placing them in a zip-lock type plastic bag to keep out moisture and dust. Coating the bearings with grease and using an air-tight bag will keep them in like-new condition for years. You can even squeeze most of the air out of the bag before sealing it.

  • Can Larger Bearing Install on Trailer if Spindle is Damaged to Point Correct Size Wont Fit
    Since going with a larger bearing is not a solution that will work or we can recommend what you'll need to do is basically try to refinish the spindle so that the correct bearing # L44649 can fit. You might enlist the help of a machine shop but basically you'll need to smooth out the spindle where it's chewed up if at all possible so that it's no longer too messed up for a bearing to fit on it.

Or if you use a dial or digital caliper you can take exact measurements for where your bearings ride on the spindle and I can determine what bearings you would need based off of that. If...

  • Replacement Trailer Grease Seal for an NOK AD2527E Seal on a Boat Mate Trailer
    To replace your NOK AD2527E seal you can use # 168233. It has an inner diameter of 1.688 inches and an outer diameter of 2.332 inches. Based on what I could find on the NOK AD2527E the inner diameter is the same and the outer diameter is 2.328 inches. So it will be a tight fit but no other seal is even close.
