possibly the driveshaft angle has been altered?is there a ride height difference between the old shocks and the new? maybe look under the car and see if you can spot a worn area now where two metal surfaces are trying to clearance each other...
I found it. the u joint bolts at the trans backed out and broke 2 of them so ill need to remove the drive shaft and replace all 6 bolts and curve washers #19151557. I guess the little four banger is to powerful. my ZL1 doesn't have enough power to break its bolts.
I will be replacing the back bone at the same time.
thanks guys for your help.
