Oil Recommendation for Oil Bath Kodiak Disc Brake Hub/Rotors

Question

Question:

I just had these installed on my fifth wheel, but there’s no maintenance instructions. I understand they use a heavy oil type of grease but need to know what to buy and how often it needs to be replaced, etc. I reached out to Dexter but they have not responded. Do you know or can find out? Thanks in advance

Hey Jascha, we offer a Kodiak oil that is designed specifically for their hub/rotors like the part # KOD53FR that you have with the part # XLPROLUBE. This is an 8 oz bottle and each hub takes about 2 oz. How are you liking these hubs so far?

Oh, I thought the KOD53FR were the E-Z lube type and not the oil bath? When I was looking at them you had a separate video for the oil bath type and the person expressed worry that a leak might cause a failure but that would be less likely with the grease lubricated type. I’m confused. I had to take them back for a second brake bleed that was causing a five second delay in their activation and then Ford had a trailer module recall that was causing trailer disconnection issues, so I haven’t put many miles on them. However, I was finally able to lock up the trailer which I wasn’t able to do with the original brakes. I am now able to tune the gain so I don’t even feel the trailer. Quite pleased! How often should the lube be replaced? And do I need a special tool? I was expecting to use my grease gun, but if it comes in a bottle, I guess not. Thanks

@JaschaL There is a bit of confusion on this the more I look at this. The cap of the hub is clearly (pun intended) an oil cap style since it threads on and is clear which is exactly what an oil bath setup uses but the title says EZ lube and the seal is a grease seal so it's a bit of a mess.

@JamesonC A person at the shop said something about a heavy oil type of grease that comes in a cartridge like normal axle grease but isn't as solid. My trailer isn't handy at the moment, but I'll make a point of taking the cap off and checking the consistency of what's there. Hopefully they added the correct type! In any case, I'll need to know the maintenance procedure and schedule along with any specific tools and supplies I'll need. Like I said, there weren't any manuals and I haven't had any luck contacting Dextor. This type of hub is new to me, I'm just used to pumping in grease till it comes out clean. So I'm counting on you guys! Thanks again.

@Jascha That almost sounds like the Dexter Vault lubrication like the part # DX83ER which is basically a hybrid between oil and grease. Since this hub/drum comes with grease seals I would go with just a grease like the LMX red part # L11380. If you put a decent amount of miles on the trailer once a year is a good amount of time to repack the bearings.

I added the Kodiak Disc Brake System on our 2018 Heartland Bighorn a year and a half ago and we absolutely love the system. I have been in the automotive restoration business for 49 years and automotive repair business for 56 years. I can tell you the Kodiak Brake System stops our trailer around 40% faster than the conventional brake system that came on the trailer. I installed the disc brake setup myself because I wanted a custom fit where it looked factory. I opted to use wheel bearing grease instead of the wet system for the wheel bearings, I didn’t see anything wrong with the wet bearing system but I guess you can say that I’m old school. I highly recommend anyone who’s on the fence about adding A Kodiak Disc Brake System on their trailer to go ahead and do it and you will be happy that you did. I

Answer 1

Hey Rick, sorry to hear about the leaking seals! Looks like the kit you had installed was the part #KOD53FR which for a replacement seal you'd want the part #GS-2250DL and then for bearings #25580 and #02475.
