Today we're going to take a look at the Kodiak XL Pro Lube Kit for 3500 pound axles. Now, this kit is designed to eliminate corrosion and leaks that are commonly resulting in premature bearing failure. This will convert your trailer from grease to oil with your existing hubs. The bearings will oiled through the centrifugal force. That will give you low maintenance, high corrosion resistance, and cooler running for longer bearing life. The body on the cap here, let me take the top off here, is an anodized aluminum construction.
It's for nice corrosion resistance. It is designed to fit 1.98 inch hubs, and 3500 pounds axles. The cap that screws on to it is a blue polycarbonate material, and you can see through it to see the level of the oil. Has a rubber plug right in the middle here that you'd pull out to fill the oil. It does have a water-tight O-ring seal around there, so when you do tighten that in, it will seal that. Now, the oil seal, you do need to replace your seals.
The oil seal is a ribbed, anti-rotation design. The seal is designed to fit 1.72 inch spindle outside diameter, and 2.56 hub inside diameter. This is not for use with the 1.68 inch spindle. The oil it comes with, this tube, or this bottle of oil, is a special synthetic formula to help reduce friction. It is compatible with your existing grease.
That should do it for the review on the Kodiak XL Pro Lube Kit for 3500 pound axles.

I have been thru 3 rear seals in 500 miles and 2 Plastic caps with this Kodiak 3500 XL lube kit,ridiculous.One cap was cracked upon purchase.My Trailer has all NEW parts 100 %. I have bought 3 extra caps,4 extra bottles of bearing lube. I now leave my decorative logo caps off so I can check my bearing lube every fuel up stop.I'm stubborn because I will not let this stupid system leaking beat me, I must stop the leaking! PS apparently I am the stupid one.

After buying many many extra seals,lube,fron seals,caps,adding sealant to caps ,spending extra xtra money we have reduced leaks almost to sta stop.
I am not happy with these hubs. The o-ring on the cap will not seal with the aluminum hub. I have replaced all of them once and they are still leaking. Currently I have went back to grease on two and still have oil on two and one of them is leaking.

Oh no, that sounds like some sort of defect. It looks like we don't handle warranties past 30 days upon delivery. Let me get some information over to you for the manufacturers warranty department.
Inner seals leaked immediately. Gave up after 30 miles and went to bearing buddies.
Wish I hadn't converted my std. grease hubs to oil bath hubs. Of the 4 hubs I converted, one keeps leaking. This will be the third re-build of that hub. Seems the rear seal keeps leaking. Ugh!
Great concept and well made product that would work well on over the road trailers.
I used them on a boat trailer with new axles and the first time I submerged the trailer water was introduced to three of the hubs. I had to go back to bearing buddies.
I installed the oil bath system per the instructions, it was easy to install, the tips I would give anyone is to take your time when installing the rear seal. Its very tight, so take your time and use a solid round object and make sure it goes on perfectly straight. It was all straight forward as far as installation, what I found different was after installation. I noticed that instead of the seal rotating over the axel, the seal stays affixed to the axel, and the outer race, between hub and seal is what moves. I've never seen this before. So I called etrailer and spoke to customer service. They checked and said because this is an oil bath system its normal for the seal to stay stationary and the movement is between hub and seal. I spent a lot of time cleaning the axel were the seal normally rides. However it seams you don't have to. I hope they are right. I'm going to follow-up after I haul some heavy loads and let you know how it goes.
Thanks

After a year I am very happy with the Kodiak XL pro lube kit. I’ve made three 1200 miles trips and other shorter trips with no problems at all. The one issue I had, that turned out to be a self inflicted installation problem my fault was that I didn’t bend the cotter pin back far enough. The outer cover is a high quality aluminum, when the wheel turns the outer cover turns and the cotter pin stays stationary. What happened was the cotter pin rubbed on the inside of the aluminum outer cover. So when I checked the oil after hauling a heavy load I saw what I thought was metal flakes in the oil. I thought the bearings where shedding chrome flakes. But after calling Kodiak tech support and talking to their support team, they said check the oil with a magnet, if the flakes are magnetic it could be the bearing, but if it’s not it’s probably the cotter pin rubbing the inside of the outer cover. And that’s what it was. All I did was jack the opposite side of the trailer and drained and flushed the oil out the service cap, made sure the cotter pin what pushed all the way in, and reserviced with oil. It has been flawless ever since. I highly recommend this conversion to a wet bearing.
I have used these hubs a dozen times and I think they’re the greatest thing since sliced bread. The lubrication of the bearings with a liquid is far superior then any grease I’ve ever seen. And the ability to check at a glance and know your bearings are protected and you can change the lube without making a mess there just plane great

Your product is still working like the day it was installed it gets used two or three times a week and usually nothing local all long run’s no leak’s at seals or cap’s and whatever the composition of the lube I haven’t had to add to the hub there great looking forward to a set of four for my toy trailer!!!
So far in one year I've been through about 7 Seals. They flat out leak. I found better luck by soaking them in gear lube before installing them. The way they're designed with an inner and outer section that seal against each other to allow it to spin with the Hub yet seal to the spindle seems to not be Lubed enough. Another issue I've had is the caps. I've been through several caps from leaking as well. I've had three caps with spider cracks. at first I assumed it was from me over tightening but after I replaced them being that they have an O-ring I just hand tightened them. two out of the four caps that I replaced and only hand tightened were cracked again. Let's just say it's been a very expensive year in comparison to just dealing with greased bearings. Really this should be a far superior system but until they get the seals and caps from failing, I'm going back to grease
They don't fit all the oil came out and locked up th bearings.i guess I got the wrong size seal.

Never could use them.wont fit
Materials used look to be of good quality, though I have seen others talk about cap quality. My largest issue is that the instructions are photocopied in black and white, losing the real ability to decipher the pictures. If you have chanced bearings or pulled hubs before, than you won't need the pictures - it's pretty straight forward. Outside of this - you will need 'red sealant' for the outer aluminum body which does not come in the kit. I've had both grease and oil hubs and by far the oil hub is not only better for the bearings and trailer, but drastically cuts down the amount of time maintaining the hubs. Largest hub saver is moving the trailer monthly to keep from Brinnelling the bearings, but this product will add a large piece of mind on those longer hauls.
I wasn’t converting to prolube. I had just bought a boat trailer with the prolube system. One axle was leaking and I only needed a cap and O-ring. The kit was a way to fix the leak and have some spare parts.
The trailer is 10 years old. The prolube system appears to have been original equipment. I could tell the O-rings were replaced once before. If you are thinking of converting to this system, just keep an eye on them O-rings. Ten years and just two sets of O-rings... not bad. Easy to swap out.
My boat trailer has been on oil bath for ten years. I will never have a greased trailer bearing again. This product easily converts existing hubs to oil bath. Installed easily and looking forward to smooth operation.
Great product you can see lube level at a glance you do not have to pack the wheel bearing every year or carry a grease gun with you all the time easy to install, last set lasted 7 years before the seal started to leak.
The oil bath hubs have worked very well and I would recommend them for any conversion. I believe the oil bath system is superior to the grease pack, but that is only my opinion. If you are considering a conversion, this is a good product to use.
This is my second trailer I have used this wet bearing set up on and I have had no problems. Just don’t over tighten the caps. They just need to be seated firmly, not torqued. Great system.
The Kodiak ProLube Kit is a GREAT. These will go on my second and third trailers. The first trailer I installed on has over 50k miles on it with NO failures. The bearings run so much cooler than with grease.
Got the items today 04/10/2020. Installed with no problems. Only two issues with the kit are, (1) THE INSTRUCTIONS LOOK AS IF THEY WERE COPIED WITH NO INK IN THE COPIER THEY ARE SO FADED OUT YOU REALLY READ THEM VERY WELL TO SAY THE LEAST. (2) AS WITH ANOTHER IDENTICAL KIT THE REAR OF PLASTIC COVERS THAT SCREW INTO THE ALUMINUM HUB BODY HAVE TO BE GROUND TO FIT, THEY ARE TOO LONG IF LEFT AS IS THEY WILL SCREW INTO HUB BODY AND HIT CASTLE NUT WHICH HOLD THE ENTIRE HUB ASSEMBLY IN PLACE ON TO THE SPINDLE, AS A RESULT, WHEN YOU TURN THE WHEEL ASSEMBLY IT WILL AUTOMATICALLY UNSCREW THE CAP AND YOUR OIL WILL POOR OUT.
These kits work great but you definitely need some mechanical ability to put them on.
So far after a few trips this seems to be an excellent product. I learned to love this type of system on a tractor trailer setup I drove. Very maintenance free. Just check the level and change the fluid once a year or so. Also makes you look at your hubs a little more often, like a person probably should, to check the fluid level.
Good quality, at a fair price. The blue lube and blue tinted outer caps make it a little difficult to see the level of oil inside. I would recommend this product. its a great idea.

Still works fine after a year
The plastic caps all broke within a couple of months and the seals also started leaking removed them and I don’t think the hubs hold enough oil to properly cool and keep well lubricated. I went back to grease bearings.
Junk ! if you have electric brakes? Leaked on brake shoes had to replace considerable cost. Would not recommend
Product will fit easy grease spindles. I didnt use the oil supplied due too its very thin. I used lucus hub oil instead.
Kodiak XL ProLube Kit has preformed very well
Leaked on brand new hubs - stick with g rease.
Do you have a question about this Trailer Bearings Races Seals Cap?
