C2 rear wheel bearings

[Richard E.]

Does anyone have the current GM part numbers for the inner and outer rear wheel bearings and shims for a 1966 Big Block? Thanks for helping.

The current GM bearings are

GM #457052---outer

GM #9417784---inner

Shims are as follows:

0.145"----GM #3820225

0.139"----GM #3820226

0.133"----GM #3820227

0.127"----GM #3820228 DISCONTINUED

0.121"----GM #3820229

0.115"----GM #3820230

0.109"----GM #3820231

0.103"----GM #3820232

0.097"----GM #3820233

For wheel bearings, both front and rear, I usually use Timken, even though I have a 1,000 year supply of the ORIGINAL part number GM bearings [none for sale].

Thank you very much Joe. Any issues with the current GM replacement bearings? Should I obtain a Timken equivalent?

I don't know what the GM current offerings are like. They are certainly not of GM or DELPHI manufacture since both GM and DELPHI have been out of the bearing manufacture business for a long while. So, where they are sourced from, I do not know. Some current GM bearings are of Japanese manufacture. The Japanese bearings are among the finest to be found anywhere in the world.
