Self lubing wheel hubs?
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.

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.
