RVing 101 - Do you Grease the Wheel Bearings on your Towable RV?

Question: At what mileage or time interval should a travel trailer or 5th wheel have the wheel bearings greased?

Mark's Answer: That’s a good question. Dexter axle recommends that along with bearing adjustment the wheel bearings should be inspected and lubricated every 12 months or 12,000 miles whichever comes first. Be sure and check your RV owner’s manual because I have seen intervals of 12 months or 5,000 miles as well.

Happy RV Learning,

  1. Bearings are the life line of any wheel or mechanical application and takes heavy loads under extreme temperature and pressure conditions. Hence lubricating bearings at constant intervals with Bearing Grease lowers the friction and provides longer shelf life for bearings thus minimizing maintenance costs and time. .

    Various grades and types of Bearing Greases are available to suit the specific requirement of a particular bearing. Selection of the Bearing Grease is very important and the maintenance engineers should strictly follow the advice of the original equipment manufacturer in the selection of Bearing Grease.
