Self lubing wheel hubs?

[Nvr_lost]

What does this mean with regards of what the owner needs to do? I have 6000 miles on my 2015 Winnebago travel trailer that has self-lubing wheel hubs. I have never had them lubricated.

I've been on the receiving end of over lubed hubs.

Here's the thread about it: The link goes directly to the post on the rebuild process Upgrades to my trailer - 8.5x20 Haulmark

From what I read and see on this Forum regarding hubs, bearings, and on new trailers, I'd suggest to have the hubs pulled off, lubrication checked, and the bearings packed and installed. There are more than a few that have found their hubs and bearings without grease or installed incorrectly. At 6000 mi., it is probably a good service interval to check them, anyway.

THIS.

Second Chance is correct about pushing the grease out the rear seal contaminating the brakes, I've done it. I understand you are to push the grease in slowly while rotating the wheel to avoid that. I don't use a grease gun anymore. Just inspected mine after about 2 years (about 10,000 miles); pulled the drums on the street side and found that the grease was good and no bearing wear. Brake linings and magnets didn't show much wear. Inspected 2, didn't bother with the other 2. I suspect the 12,000 maintenance is a safety number which is more important if the axles are submerged like on a boat trailer. I do check brake drum temperature occasionally with an infra-red gun.

If greased bearing rather than oil bath, be VERY careful shooting grease in there with a grease gun via a Zerk fitting. It's very easy to blow grease out the back grease seal and get grease on your brake drums and pads. Greased brakes don't work very well. Many experienced RVers advocate pulling the hubs on this type of setup, cleaning and inspecting the bearings, and packing them by hand annually or every 12,000 miles - whichever comes first.

Good to check manufacturer. They are probably grease and you do need to have a shot of additional grease.

Are they grease or oil bath hubs? I would search the OEM axle maker's web site for service interval requirements.

Haven't herd of those. Do they have a zerk fitting on the end of the spindles? Maybe what you mean is E-Z lube hubs?
