Default Torque Arm question....

I have a BMR adjustable TA on my WS6. I had it installed when the car was lowered (Eibach ProKit) and I just recently put the stock springs back on. I've noticed now that when under anything more than a slow take-off I get a horrible tump/bang from the rear end on the 1-2 and 2-3 shifts. COuld the difference in TA angle be causing the thumping? I checked all the bolts on the TA and they are still torqued all the way down. Since it's back to stock ride height do I need to re-adjust the angle on the TA? I'm just trying to rule out the simple stuff before I tear into to diff.

Yes you do need to readjust the angle. Also check to see if the springs are sitting in properly.

Thanks, that's what I figured but it never crossed my mind when I raised it back up.

You will need to reset the pinion angle. If you have any other question that I can help you with please feel free to ask.
