I just got spare axleshafts for the front 10 bolt. They have this small backing plate on the stub shaft. They are pretty beat up, so what are they, do I need them, and where do I get them? Also are there any bearings that are supposed to be on the shafts? I am getting spare axleshafts for the rear also, and was wondering if there are any bearings or backing plates, etc that need to be pressed on or is the shaft all I need? Thanks Harley My Chevy isn't broken, its just out of gas.
