Just got my 2011 2SS camaro conv. L99 back from the dealer (1500 mi.) for the grinding noise. They replaced the seals with GM P/N 22797705 and drain / refilled the dif. with new fluid GM P/N 88862624. Advised it may take up to 500 mi. to penetrate the limited slip clutch. This fluid includes a limited - slip additive. My dealer said Im the first customer that has complained of the problem.I still hear grinding noise, I dont blame the dealer just dont think GM has found a cure.
