Now, it seems that the rear wheel bearing failure was so loud it was hiding a bit of a rear end whine. I think it may be the carrier bearing on the side that had went bad, the axle was so chewed up it had to have put an undesigned strain on that carrier bearing. Struggling with whether I want to go ahead and get it fixed or wait it out a while. I can get its done now for between $550-$750...idk.
Chris, you've had everything but the carrier out at this point. You could pull that and have the new bearings pressed on it and reinstall. It should go back to the same position with the factory shims and be fine. Just a thought to save you some $$, Pulling the carrier really isnt to hard. You should probably be able to have the bearings pressed on for $20-40 I would think. I put a different carrier (LSD) with new bearings in my S10, used the fatory shims and it was perfect. I wasted that money on the shim kit I bought. It really should be just a simple R&R to change the bearings and that price seems steep to me unless your changing all the bearings and getting new gears......
