Guys,

Need some advice. I just pulled my diff and sent it to a shop to swap out the 3.45 to 3.91 ring and pinion. While it was there I also had them press in harder carrier diff mounts. I put the diff back in myself. (Pretty easy job)

So my issue:

When the can is in first gear and I have the clutch pressed in and i start to release the clutch i hear a whap, whap whap sound from the rear end. At least it sounds like its the rear end. Are the harder bushing causing this? Due to less flex in the rear end? Should I put harder bushing in the transmission now? Really frustrated here any advice or help would be greatly appreciated.
