from a stop with the wheel all the way turned, almost at lock - under throttle i'm getting a low grumbling sound. could that have something to do with the torsen diff? Also getting a high pitched whine mostly in 5th and 6th when feathering the throttle around 2 to 3000 rpm. could this be a pinion bearing installed wrong??
The whine is minor but when my girlfriend said something i knew it was a concern ( being that i don't think she'd say a word unless the car was on fire) this tranny was stupid expensive and i don't ever want to do it again, but if it has to be done i need to know while under warranty TIA
