How Often To Replace Wheel Bearings. The official answer is that you should service your bearings once per year. Im sure I replaced them somewhere around 20000 miles the first time.

Although not mentioned in the Jaguar literature the front bearings should be cleaned and repacked with fresh gease from time-to-time. You have to understand that the wheel bearings do have a very long life span compared to other parts of your motorcycle. This is only a rule of thumb though the actual lifespan of a wheel bearing depends on the quality of the wheel bearing and the operating conditions.
Often times you can search your trailers owners manual for the proper time to change your wheel bearings.
Disassemble the bearings from the wheels one by one carefully. Harley wheel bearings are now smaller and since 2008 this has made bearing failure an issue. Motorcycle wheel bearings need to be replaced between 20000 miles and 100000 miles. Rotate the wheel if it doesnt move smoothly through a whole rotation the bearing needs replacing.
