So I had done the reinforcement job on my car a few weeks ago and ever since there has been a clunk in the rear end when taking off, and also if I go on and off the throttle quicker there is a clunk. So when I started looking around I realized I had put the diff bolts on the wrong side, so front was on back and back was on back, go ahead and laugh I know. But I swapped those around and the clunk was gone... for a little bit, after a while of driving with absolutely zero clunk, it came back. I had them all down to the correct torque which was about 60 ftlbs. Any ideas on what else it could be? And should I have put loctite on all 4 subframe bolts?
