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.

It is working great! It is a perfect fit to the trailer hub.

Put these caps in the CE Smith hub assembly in order to have easy access to the trailer spindle zirc fitting. Used a 2” pvc pipe to drive them on the hub. Looks good. James and Kate were excellent to work with at etrailer!!!

Awe man, I am sorry that these werent the caps you were wanting. I see that our customer service department has gotten a new order placed for you for bearing buddies. When you receive the new order, I would love to hear your updated feedback.



by:

I called etrailer about a question on the size of the grease caps. They were very helpful and by knowing what bearings I used we determined the grease cap size. Shipping was fast too.



by:

I use these caps on my boat trailer which is used only in salt water. Even with thorough rinsing after every use, the zinc plating on cap rusts out and the rubber plug cap gets dry rotted from sun exposure in less than a year. Still works OK if you smear a coat of grease all over the outside of the cap and the rubber plug.



by:

They can prove difficult to put in but it takes some time! I truly believed these were incorrect size but eventually got all 4 on and they are guaranteed a tight seal! Don’t give up if you are having trouble putting them on and don’t drill or cut them to get them to fit either! I saw that on you tube as a fix but it’s not necessary! Use a strong rubber mallet! That’s what did the trick for me!



by:

The fit on my Dexter hub is perfect. These, along with etrailer bearing/seal kits are being replaced as general maintenance. Great product!



by:

Great replacement for original equipmen t.

A perfect replacement for the battered and worn caps on my EZ Lube axles. Order dust cap driver p/n 290-991 for easy installation and removal during service.

Thanks for taking the time to follow up with me. Ive only put a few hundred miles of use on the trailer but everything is working great. Ive actually recommended etrailer to my father, a friend of mine and anyone at work who would listen made easier by the fact that I had everything I ordered shipped to my job instead of home. Barring an emergency situation that requires an immediate solution you have my business in the future.



by:

perfect fit! good quality, no issues



by:

Not quite the same as OEM. Metal is slightly thinner and had some trouble installing



by:

Shipping with etrailer was very fast. After having these grease caps for a year I can say that I am very happy with my purchase. Fitment was perfect and quality is good. Would purchase from etrailer again.

Steven

Still good and hasn’t budged after 2 years.



by:

Perfect plus it was delivered on time. Great service thank you.



by:

The grease caps were exactly as described and fit properly. The shipping was very fast and e mails keep the buyer informed very well. I will certainly buy from etrailer.com again. Thank you



by:

It was time to repack the bearings on my 12 foot utility trailer and I needed a dust cap with simple / clean access to the grease fittings. The RG04-040 was the perfect solution, easy to install and looks great too!



by:

Grease Cap fit perfect and the rubber plug fits nice and tight. No water or dirt is getting inside. I highly recommend you purchase the Dust Cap Driver Tool as I did. They fit tight and the tool puts equal pressure all the way around. Your going to flatten the edge out if you don't use this tool for sure. Do it right the first time.



by:

Good grease caps.



by:

My current grease caps are a bit worn and one in particular doesn’t like to stay seated. Needing replacements and having great experiences with etrailer - I purchased these replacements. They do exactly what they are supposed to do and seem to be of better quality than some others I have seen.



by:

Just what I needed

I'm a "Return" customer & have been completely happy with the products & service provided by etrailer. They have met & exceeding my expectations!
When I have trailer needs they are my go to resource moving forwards!
Keeping my trailer in Great Shape!

    We do have a large selection of grease/dust caps currently available.

I recommend using a digital caliper like # PTW80157, as the measurement will need to be as accurate as possible. The hub's pilot hole should be just a tiny bit smaller than the cap so that the cap will fit nice and snug. Based on my research, the 3,500 pound hubs that your Lippert axle...

  • How Does The EZ Lube Spindle # TRU74FR Work On A Boat Trailer
    On the EZ Lube Spindle # TRU74FR you do not need a grease fitting for the hole on the inside end of the spindle. This is an EZ lube spindle which is designed to allow you to put grease onto the bearings by using the zerk fitting on the threaded end of the spindle. You will not want to block the hole that is on the inside end of the spindle. When the hub is installed on the EZ lube spindle it will form a cavity around the wheel bearings and when you pump grease into the spindle through...

  • Do Hub Races Have to Be Changed if Different Brand of Bearings Are Installed
    No, so long as you replace your worn bearings with appropriate equivalent ones from another brand the races do not automatically have to be changed too, but there is certainly a chance that if the bearing are shot the races may have wear too. This should not be difficult to see though. You can inspect the races and your spindles for signs of scoring or discoloration from excess hear. If they all look good then replacing your bearings alone is okay.

  • What Grease Seal is Needed for Trailer Hub with Bearing Numbers LM67048 25580
    For that bearing combination there are two grease seal options that are possible. For whatever reason the 5.2k to 7k axles kind of randomly either will have a 2.125 inch inner grease seal requirement like the part # GS-2125DL or 2.225 inch like the part # 10-36. There is no way to know for sure what you have without measuring so you would need to measure the outer diameter of your spindle where the seal rides to know.

  • Are the EZ Lube Grease Caps Waterproof
    The rubber grommet for the Grease Caps # RG04-040 will create a seal that helps keep water and other contaminants out of your hubs, but no grease cap is really "waterproof". The EZ lube caps are going to do just as good of a job as normal grease caps though if that is what you are wondering. The best way to keep water out of your hubs is to make sure that they have the proper amount of grease in them in addition to a grease cap.

  • Replacement Bearings and Grease Cap for PWC Trailer
    Your PWC trailer will almost certainly have a 2K capacity axle. The correct bearing set will depend on the reference numbers on your existing bearings, both inner and outer. You most likely have either a L44643 or L44649 as an inner and outer bearing. Whichever of the two you have, the # RG04-040 would be the correct dust cap for your EZ lube spindle. If you have the L44643 bearings, the # BK1-100 bearing kit is what you'd need. If you have the L44649 bearings, use # BK1-150.

    The Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Off-Road Tires - 3,500 lbs # ASR35HDS02 is compatible with I-beam frames and in tandem axle configuration. Due to the Aluminum frame, I recommend putting a thin rubber pad between the steel mount and the aluminum I-beam. The powder coat on the steel should keep the two dissimilar metals from galvanic corrosion, but a thin rubber pad would drastically increase this safety. Zinc plated hardware will work well with...

  • How to Pick Out Dust Cover with Rubber Plug for Tow Dolly with EZ Lube Fitting
    What you are looking for is a dust cover for an EZ-Lube spindle hub. We definitely can help but we need to know the diameter of the cap so that we can pick out the correct one.

If you have a 1.99 inch diameter you'd want the part # RG04-040, if you have a 2.45 inch diameter you'd need part # DC250L-DCRP, or if you have 2.72 inch...

  • Missing Zerk Fitting on Boat Trailer Grease Repack

  • Needing EZ Lube Boat Trailer Hub With 1.25 Inch ID Grease Seal and L44649 Bearings
    We don't offer a hub kit that meets all the parameters you mentioned, we have a couple of options that would work. Your boat trailer used an oddball hub/spindle combination, which was used by Ranger and a couple of other boat manufacturers with the idea being that you could only get the replacement parts from them. We do have an option, but you'd need to purchase the correct EZ Lube grease cover separately. The CE Smith Hub Assembly, part #CE13311 is compatible with 8 to 12 inch wheels....

  • Solution for Trailer Axle without Grease Fittings for Easy Install of Grease
    There isn't a way to install zerk fittings on your spindle to make it an EZ lube spindle, but we do have Bearing Buddies which are designed for spindles like yours that do not have the zerk fittings to make installing grease in them easier. You have to pick them out based on the diameter of the grease cap they'd replace. So if you had the grease cap part # RG04-040 that you referenced you'd need the Bearing Buddy part # BB1980A-SS would be the kit to use. These have a grease fitting on...

  • How to Determine Which Grease Cap and Center Cap will Fit My Trailer
    To determine if the grease cap # RG04-040 will fit on your trailer you will need to measure the inner diameter of your trailer hub's pilot hole. This will need to be measured as accurately as possible so it's best to use a digital caliper like # PTW80157. The # RG04-040 will fit a pilot hole that is just slightly smaller than 1.99 inches. The hub's pilot hole needs to be a bit smaller than the cap so that the cap fits snug. If that cap is not a fit, I've linked our selection of grease...

  • What is the Bore Size of the Dexter Trailer Hub and Drum Assembly # 84557UC3
    A 1.98 inch inner diameter bore is pretty common on trailer hubs. If you were to measure the bore diameter of the Dexter Trailer Hub and Drum Assembly, # 84557UC3, using a dial caliper, you would get 1.96 inches. This hub requires a grease cap with a 1.98 to 1.99 inch diameter. The grease cap that comes with this hub actually measures 1.99 inches. If you are looking for a replacement dust cover, you have many options. For a standard dust cover, you can use part # F001518 or # RG04-020....

  • Bearing Kit and Dust/Grease Caps for Coleman Mesa Camper with L68149 and L44649 Hub Bearings
    As far as bearing kits go # BK2-100 is the only one that has both the L44649 and L68149 bearings. The seal that is included is a 10-19 with an inner diameter of 1.719 inches and outer diameter of 2.565 inches. Based on my research this is the correct seal. Your hubs should have a center hole for the grease cap that is a little under 1.99 inches. Use calipers such as # PTW80157 to measure the hub bore to be certain. For a set for EZ Lube axles use # RG04-040. For a set of regular caps use...

  • Does The Bearing Buddy Protect the Bearing from Water
    When the hubs get hot, and then backed into water for unloading, they have a tendency to suck water into the hub. Normal dust caps will not offer much protection. If you are looking for a bearing cap replacement that keeps out water and dirt, then the Bearing Buddy would be what you need to consider. The Bearing Buddy, like part # BB1980A-SS that fits a 1.980 hub bore, also includes the rubber protectors. You would have to either have the outer bearing number, or take an exact measurement...
