Not my buick but my 66 Jetstar. Its a small block car with the 8.2 rear. I am replacing the rear wheel bearings every 5k-7k miles. It's driving me nuts. I believe this is a typical bop 8.2. Maybe someone can offer some insight. Here is what i know- Normal bolt in axles with a sealed bearing. Both sides have been failing The car has 2 new moser axles due to the failures ruining the old axles. Both new axles have had bearing failures... The bearings still have a press fit to the axle. The car wears tires perfectly and tracks arrow straight. Im wondering if the bearings need to be shimmed somehow? Maybe there is too much clearance from the retainer to the bearing? This is driving me nuts!! Anyone?
