Popping from rear differential
Had the friction additive and new gear lube done about six weeks ago; now the noise is back. Do you guys recommend the new clutch packs? Is anything in there going to be harmed if I do nothing. Has anybody heard of solving the problem permanently with an aftermarket gear lube? Thanks in advance for any input you can provide.

Before letting the dealer disassemble your car, try adding another bottle of GM friction modifier to your diff. (part number 1052358)
This made my rear silent after 2 drain and flushes failed to solve the problem.
And yes, my car still leaves 2 very black strips of rubber when doing a burn out.

Took it in on a Monday, diagnosed problem, ordered entire rear diff assembly, received it on Thursday, finished it on Monday. Picked it up on Wednesday.
There were 4 others in there getting the same treatment.

Way back when I had my C6 Z51, I had it to the dealer twice for the same thing, the first time they did the GM fix of drain and additive, the second time they put a synthetic fluid in the rear and no problem. I don't remember what it was but I think it was something other than the GM fluid. If all else fails, buy a Z06, you won't have that problem.
