How Often Should RV Wheel Bearings Be Repacked?
Wheel-bearing service intervals vary by axle and hub design. A generic annual rule can be conservative for some setups and insufficient for others.
Identify the axle or hub manufacturer
Travel trailers commonly use axle assemblies from specialist suppliers, and the service procedure may differ by bearing and lubrication system. Find the axle tag or hub documentation before assuming a procedure.
Time and mileage both matter
A trailer that sits most of the year still experiences grease aging, condensation and seal deterioration. A trailer traveling thousands of miles sees more rotational wear and heat cycles.
Hub temperature is a useful warning sign
A hub running materially hotter than the others after similar driving can indicate brake drag, bearing problems or lubrication issues. Temperature checks are diagnostic clues, not a substitute for scheduled service.
Do not over-rely on grease fittings
Some systems allow grease addition through a fitting, but pumping grease does not inspect bearing condition or guarantee grease stays away from brake components. Follow the manufacturer’s procedure for the installed system.
