I was nice but stern complaining about noise while turning left, they said they would rebuild it. I told them the GM knows about the gear issue and they should replace it new, they agreed.
Than said GM wouldn't warranty it if the motor or computer has been changed. I told him everything is still factory, he laughed because he can hear and see the difference, after all she's running 563rwhp and loud as hell. They fixed it for free and I tipped the service guy and mechanic $50 each. good to go for another 4 years.

So what were your mods?

I like your style BTW. They hooked you up and in return you payed for a nice steak dinner for each of them.

Glad you didn’t have to wait for your diff.
