Video Transcript for Kodiak Synthetic Bearing Oil for Oil Bath Hubs Review

Connie: Hey, guys. How's it going Connie here at We're going to be taking a look at the Kodiak synthetic bearing oil today. So our bearing oil here comes in a nice little convenient eight ounce bottle.Keep in mind for installation, the only thing we're really going to need is a pair of gloves, because we want to avoid getting this on our skin. We're also going to need some sort of pry tool such as a screwdriver, so you can pry free the cap on our oil bath hubs.So the biggest question you're probably wondering is how much you need. And that's going to be based on how many axles and how many hubs we have.

Now for our fifth wheel trailer here, it has two 7,000 pound axles. But what we found is about one and a half bottles is going to be enough to fill all four of our hubs here. So you can keep that in mind and order the amount that you need based on the number of trailer axles you have.So our bearing oil is going to be designed specifically for Kodiak oil bath hubs. However, it can be used with pretty much any other manufacturer's hubs as well. You just need to verify that the weight rating of the oil is correct.

This oil has a 90-weight, which is going to work for most trailer, brake hubs here, such as these Kodiak. So as long as you verify with your manufacturer, you should be able to use this no matter what brand of hubs you have.So with regards to oil versus grease lubrication, I definitely prefer the oil. It is a little bit less cost-effective than grease. But however, I'm sure if you've messed with grease, it gets really messy. It can be a pain in the butt to do your yearly maintenance.

In regards to the oil bath here, it's not going to be messy at all. It's going to be super simple, therefore maintenance is going to be a lot easier.In order to properly service our hubs here, what we're going to want to do is first, we're going to remove our rubber cap here. Going to pry that off, and that's going to allow us access so we can fill our hubs here. So then once we have the cap off, what we're going to do is, we're going to take our nozzle here. We're going to point it inside this little opening here, and then we're going to gently squirt in our oil while we're turning our hub at the same time.Now, we don't want to make big squirts.

Just want to slowly let it out as we're rotating the hub. Once we feel we have a good amount in there, we can go ahead and stop and let the fluid settle. What we're looking here for is a slow drip out of the bottom opening here. So once we get the slow drip there, we know they're full. We can put our cap back on.However, if you're doing a new installation, chances are, you're going to need to repeat this process a couple times to let all the oil sit down and go back in the hubs here. So, it looks like we could add a little more here. So, then we're going to stop. What we're looking for here is just a little bit to start dripping out.Once that does so, you can go ahead and wipe that off, put our cap back on. You can see here, we do have a little bit coming out there at the end there, which is perfect. Just what we want. You don't want to make a big mess right now. So, just going to clean that up. And we can insert our cap or our plug back into the cap, just like that.So we went ahead and let our hub sit a little while to let the oil work into the hubs here. We didn't need to add any more here. You can see, we have a perfect fill line, which is going to be right below the plug on our cap here. So now we know we have the perfect amount of fluid in order to properly lubricate our bearings.So overall, our oil bath lubrication here is going to be a lot less messy or easier to maintain than our grease lubrication, which is why I prefer upgrading if applicable. For our particular trailer here that we're upgrading the disc brakes on, there is an application for both grease and oil. So if you have the extra funds, I definitely recommend checking out oil bath lubrication here and using our Kodiak synthetic bearing oil. And that's going to do it for our look at the Kodiak synthetic bearing oil.

Customer Reviews

Kodiak Synthetic Bearing Oil for Oil Bath Hubs - 8 oz Bottle - XLPROLUBE

Average Customer Rating:  4.9 out of 5 stars   (15 Customer Reviews)


Items were delivered timely, clear cap same as OE on trailer, oil east to install from bottle, oil being for wheel bearings, I don’t believe it will discolor the clear caps as gear oil will do.


Great product, bearings run 20 to 30 degrees cooler.

better than expected! After 5k miles oil still looks new.
Ray - 03/03/2022


Product seems to be great quality. Only time will tell. However, I would like to provide a review of etrailer's customer service. I made a mistake on the shipping selection online, so I called customer service. It was outstanding! Issue taken care of quickly and professionally. The item shipped, and was received, in a very short time. I am well pleased with this transaction, and would highly recommend etrailer to anyone who asks.


Great size. A little difficult to use to fill the hubs, with practice it works.


Great product and service


Easy to use with tip out spout on cap and easy to store as it is a small size container.


very expensive. about $ 4.00 an ounce. Couldn't find elsewhere. (Including Frt.)


The whole Kodiak bearing oil system is the best. I have changed all my trailers over to this system and I highly recommend it. You will not be disappointed.


Products received as ordered in a timely manner. Ordering process easy. Highly recommend etrailer for your trailer needs.

  • Recommended Synthetic Bearing Lubricant for Kodiak Oil Bath Hubs
    In your oil bath-type hubs you will want to use any 80- or 90-weight synthetic gear oil. My contact at Kodiak confirmed that the brand of oil is not important but that use of a synthetic oil in this viscosity range is what matters. As it happens though, the brand of synthetic 90-weight bearing oil we offer is Kodiak, part # XLPROLUBE.

  • Replacement Plug and O-Ring for Kodiak XL ProLube Oil Bath .98 Inch Diameter Hub Body and Cap 1
    We do offer the replacement plug as part # XLPROLUBE-PLUG but Kodiak doesn't offer the O-ring as a replacement item. For the 1.98 cap, plug and o-ring, you'd use the part # xlprolube1980 that you've already looked at.

  • How to Determine the Correct Oil Bath Cap
    To figure out the correct oil bath cap, you will need to know your axle's capacity or size of your hub bore. For a 3,500 lb hub or 1.98" hub bore you would use Kodiak XL ProLube Oil Bath Hub Body and Cap # XLPROLUBE1980, or for the kit you would use # XLPROLUBE1980KIT. If your axle had a capacity of 5,200 lbs or 6,000 lbs, or 2.44" hub bore you would want Kodiak XL ProLube Oil Bath Hub Body and Cap # XLPROLUBE2440 or if you wanted the kit you would use # XLPROLUBE2440KIT.

  • Which Oil Bath Cap Do I Need on a 2003 EZ Loader Trailer
    In order to determine the correct oil bath cap you'll need to measure your hub bore or find the weight capacity of your axle. If you have a 3500 lbs. axle or a 1.98 inch hub bore you will want part # XLPROLUBE1980 or # XLPROLUBE1980KIT for a kit that includes caps, seals, and oil. For 5200 or 6000 lbs. axles that have a hub bore of 2.440 inches you will need # XLPROLUBE2440 or # XLPROLUBE2440KIT for the kit.

  • Does Kodiak XL ProLube Oil Bath Hub Body and Cap # XLPROLUBE1980 Come with Seals
    The # XLPROLUBE1980 comes with the seal for between the screw on portion of the # XLPROLUBE1980 and the metal housing. The actual hub seal is not included so this would be what you would want.

  • What Would Cause Water Intrusion on Oil Bath Hubs
    Are you backing your trailer into the water when the hubs are hot? Typically that's what causes water intrusion into trailer hubs that use oil seals. If the seal can keep oil in without leaks it would be waterproof so the hot hub theory is probably correct. Let the hubs cool down and you should see the issue stop.

  • Replacement 250-031468 Seals Needed for Reliable Oil Bath
    From my research it looks like the correct replacement seal for your Reliable oil bath kit is the Replacement Seal # XLPROLUBE1980SEAL which is used for 3,500 lb axles. This seal has a 1.72" inner diameter and a 2.56" outside diameter. You can use these specs to ensure that it fits your application. I am unsure about the screw you mentioned because none of our kits have that screw, they just use rubber plugs similar to what you would see on an EZ Lube grease cap. If you are needing to...

  • What Kind of Oil Should be Used for Oil Bath Hubs
    If you are wondering how to lubricate the Bulldog Square Jack # BD182701, that you referenced, then you will simply need to fill it with grease via the grease fittings. If you are referring to an oil bath on your hubs, like the Kodiak XL ProLube Kit # XLPROLUBE1980KIT, then we do have bearing lube listed as part # XLPROLUBE which is an 8 Ounce bottle of synthetic 90 weight oil. I have attached a photo of the back of the bottle which reads "Fill to manufacturer's specifications". I do...

  • How to Change Grease Setup to Oil Setup for LoadRite Axle 6009.106
    To convert your grease setup on your Tie-Down axle to an oil setup you will essentially just replace the grease seals and caps with the oil seals and caps that come with the kit # XLPROLUBE2440KIT you referenced. Aside from that the only other thing you need to do is completely clean out all of the grease where these will be installed. The bearings, spindle, and inside of the hub need to be grease free because sometimes the grease will react with the oil and actually damage your setup. Please...

  • Can Regular Grease Trailer Hubs be Converted to Oil Bath Hubs
    The choice of oil bath or regular hubs is up to the manufacturer. They are usually found on higher capacity axles, though as you know there are some on lower capacity axles. You can convert some hubs from grease to oil bath using a kit such as # XLPROLUBE1980KIT but for others it would not be possible without changing the hubs. This is because oil bath hubs use an oil cap that threads onto the end of the hub. Most regular hubs are not threaded so you would not be able to screw on an oil...

  • Can Grease Hubs be Converted to Oil Bath Hubs
    Depending on the type of grease hub you have, you may be able to convert it to oil by using the Kodiak XL ProLube Kit # XLPROLUBE1980KIT. Based on the inner and outer bearing numbers that you provided, you most likely have a 3,500 pound axle, although I still recommend verifying this. This ProLube Kit will work with the 3,500 pound axle if the spindle features a 1.72 inch diameter where the grease seal sits and the existing grease hubs have a 1.98 inch grease cap flange diameter.

  • Could Kodiak XL ProLube Kit XLPROLUBE2440KIT Fit 7,000 lb Dexter D70 Hub
    If the bore on your hub matches what the Kodiak XL ProLube Kit # XLPROLUBE2440KIT is designed to fit at 2.44 inches this kit would work well in the hub. When picking out replacement caps or in this case using this kit to convert to oil bath all that really matters is matching the seal and hub bore dimensions. The seal dimensions are 2.25 inch inner and 3.376 inch outer.

  • Can Grease Hubs on Shorelandr Trailer Be Converted to Oil Bath Hubs
    Whether or not your existing hubs can be converted to oil bath units depends on the type of hubs you have on your Shorelandr Trailer. For many standard, grease trailer hubs, it is not possible to make this conversion because oil bath hubs use an oil cap that threads onto the end of the hub. Most regular hubs are not threaded so you would not be able to screw on the cap. In this case, you would simply need to replace the hub assembly with specific, oil bath hubs. If you are able to convert...

To install the kit you are going to need to remove your current hubs, bearings, seals and caps and use degreaser, making absolutely sure there is no grease remaining.

As you mentioned, you may need to remove the zerk fitting to allow for clearance with the cap but that would be the only reason it might not fit right out of the box.

  • Does Kodiak XL ProLube Kit # XLPROLUBE2440KIT Come with Everything Needed to Convert to Oil Bath
    Is there a reason you want to convert to oil bath? I personally don't like to recommend oil bath over grease as with grease if you have a seal issue you'll be able to get home to fixe it as the grease isn't going to just all pour out whereas with oil if the seal goes out you lose all lubrication and the hub is damaged within a few miles. That said all you need is the Kodiak XL ProLube Kit for for 5,200-lb to 6,000-lb Axles # XLPROLUBE2440KIT as it comes with everything needed. The seal...

  • How Often Should Oil in Trailer Oil Bath Hubs be Changed
    The common recommendation with oil bath hubs is to not mess with them at all as long as they aren't leaking or the oil isn't milky looking. Some say to change every two years but most will say that as long as everything looks good just leave it be. Also 50 weight gear oil is recommended. I am sure there is an Amsoil product for that.
