Hi Guys
Can anyone tell me the Bearing Numbers for my 1974 C30 14 Bolt Rear Axle Centre with 4.10 Ratio?
I was going to try and buy a Bearing Kit from the US, but a $100 freight bill just put them out of my reach. So I will try and get them here in Oz, but nobody has listings for Chevy Trucks, honest !!
If someone could tell me the Bearing numbers that would be a big help.
The Rear Axle is still complete and running but the bearings need replacing, so I would like to get everything before I tear it down.
Regards
Bill

Here's what I get from the 1973-1978 parts book for a 1973 corporate 14-bolt:
Bearing, Rear Wheel Outer GM 7451812
Bearing, Rear Wheel Inner GM 7451928
Bearing, Diff. Side GM 7451928
Somebody who's torn one down, does that jive that the bearings on the diff side and the wheel side of the half axles is the same?

Hi Rich
Thank you for that information, you wouldn't have the Pinion Bearings listed as well would you.
Interesting that the Side Bearing are the same as the Axle Bearings, Hmmm
