Light aircraft wheel bearings need to be serviced too. Some aircraft manufacturers recommend it every year where as other manufacturers recommend 200 or more hours (even with the same type and brand of bearings).
The job is not a very difficult one, somewhat greasy maybe. It can be done in about one hour per wheel/bearing and if done properly it will keep the aircraft rolling smoothly for many years to come.
Below we explain the procedure and show it clearly on images. This document can be downloaded and printed for reference on the job. It is written in the Dutch language but images are accompanied with English text.
