Let me start by saying that my 1997 FZJ80 is my fifth different Landcruiser, but my first 80 series. I’ve owned this particular cruiser since 2006 and have needed to have the front wheel bearings retightened and repacked at least five times now. The bearings have been loose at times, and at other times the outer seals have leaked. Is this normal for the 80 series? How often should I expect to need to go in there and do this?
