today after work i took my car (1998 camaro v6) to grandfathers shop(mechanic works for nissan ) and he checked out the rear and said its shot...so i need a new one. He said,because its real hard to "set up" the rear gears so what i want to know is this the best path to take or should i go somewhere like aamco to get them to fix it?[/align]

 

What was going on with it before? Meaning, why did you take it in?

 

it started howling when i hit the gas.

 

I would recommend getting a second opinion, as we all suggest around here. Sounds like some new gears will be in order though.
