What brand of rear gears are you guys running in your 10 bolts?
My shop called today after the gear swap and they are not pleased with the "chirping" noise from the rear diff. The shop has been working on my car for years, done all the installs and they have performed numerous gear swaps for GM rear ends.

I had them put in Motive 3.42's from Thunderracing

The have double checked all clearances, backlash, etc...he is taking the diff cover off tonight to check the wear pattern and if it looks ok, Im pretty much stuck with these, will have to either put the originals back in or get another set let alone re pay for some of the labor!

Thunderracing is of course blaming it on the installers.

Anyone had noise with these and what gear sets are the best as far as above...........thanks!
