OK, my current housing has a bad vibration in it, my local Mopar guy pointed out that it looks like the housing is bent...all driveline parts are new, U-joints, driveshaft, bearings, pinion angle is correct (street setup) etc, etc...

What local Detroit shops are capable of checking the housing for being straight? I have a spare one that I'm thinking of cleaning up and getting ready for a swap.

I'm thinking DTS??? Anyone else?

Thanks!
