I cannot get my sub-frame to quit shifting. The rear bushings took a crap so I replaced them with Dorman ones. Now every time I turn it shifts the sub frame around. I only know because after turning right, the car stays wanting to turn right. After turning left, the car stays wanting to turn left. After I hit a few bumps, it clunks around and shifts back straight. Also, I can see where my sub-frame bolt heads are moving around in the lower bushing cup.
Am I doing something wrong here?
First I tightened them all to 90 ft-lbs. That clunked a lot. Then 110. Thats better, but sometimes harsh clunks and shifting. Then 125 ft-lbs. Better, but still shifting. I did drop them all down to take a look at it all. Let me tell you. I stripped one threaded insert and broke another off in the frame. So much fun to repair.
Another question I have is what shape are the cups in the top of the sub-frame supposed to be? Are they supposed to be straight or tapered? Mine are in a cone shape.
And, is it these crap Dorman bushings causing my problems? They are really soft feeling. Did I over torque?
