Glad this subject has come up.
I have to wonder why the wheel bearings need repacking so soon. I have not done any off-roading (unless you count a few gravel drives and an occasional u-turn in an interstate median designated area ) that would provide excessive stress on the bearings and splattered mud.
No other vehicles I have owned (Jeeps, VW's, Toyotas, Hondas) with 150K-plus miles have ever needed wheel bearing work.
Have I been especially lucky, so far?
