If you have the HO52 rear axle you are out of luck on finding affordable replacement carrier or pinion bearings at the local auto parts place. Randys is the only place I know that stocks the replacements of ball bearing type hO52s

Outer bearings are available at local auto parts house.
If you have the Dana 60 rear all bearings are available, axles and brake parts not so much
