0Rear diff crunchy sound...

[Brn N Rubr]

I think I've finally found the noise coming from the rear end of my car. 15 GTPP, Gen 2R, 625/550 whp, factory 3.73/Torsen. What would the masses suggest as a replacement. I'm seriously considering a 3.31 pumpkin swap. I'd love to hear from other that have done it. I'll just need FORSCAN at the end to reprogram the BCM, right? Also, what other suspension stuff would be recommended at the same time? I've already got the cradle alignment and aluminum diff bushings from Steeda.

That is why some of us don't like torsens.

I bought the car new in Nov '14 and installed the VMP at 30k. It's been my daily driver the entire time and has 87k on it now. I guess it was expected to happen at some point. I've taken it to the drag strip a few times but never on a tire. Funny enough I just bought my VMS drag pack last week. Guess I better do the diff before I try to launch it.

If you like the torsen style the Detroit tru-trak is stronger, but the Trac-Lok is what I'd put in it.

I definitely don't think the Torsen is the way forward for me.
