I had a fun time chasing down the pinion bearings and seal for my rear end. The axle I have is not in the factory manuals as it was added by the finishing company, so it came down to chasing numbers thru the axle manf. and finaly taking them to a bearing house.
If you have the patience to do the legwork, it can pay off big. Dont count on most bearing places or FLAPS to do it for you, it can take a while and the avg. person at the counter just doesn't care as much as you do.

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
