Corvette Performance - Clunk, knock, thump, rear, diff, trans and bump.

Figured since I just got finished hunting for a strange noise in the rear of my C5Z I would make a thread with some of the keywords cause I had very little luck when searching the forums. I was getting a Clunk, knock, thump from my rear, diff, trans on my 2003 C5 Z06. It turned out to be a backed off axle nut, I applied loc tite and tightened and it cured it. This caused a very light clunk when changing gears at the moment you release the clutch. Ok, I hope this contains enough keywords that anyone else having this problem can find it.

I get this in my GTO all of the time. All my bolts look fine, I'm lost :bang:

Could be that your need differential fluid additive.

i have this problem too, slightest clunk, i'll have to check for something loose, what else could it be?
