FMS Aluminum DS and New U-Joints = 70 mph+ Vibration
I had new Spicer U-joints installed in my FMS driveshaft as it had upwards of 90K miles on it and there was the "kink kink" noise when the car was in gear and rocked back and forth. Turned out the rear U-joint was the culprit so I had a local shop that sold the Spicer 1330's install them as I did not want to mess with the aluminum. I watched them do it and they had a really slick way of pressing the old ones out and the new ones it so that it did not put a lot of stress on the aluminum ears where the caps are pressed in.
Got home and intalled the DS and took it for a spin and now it has a vibration at 70+ mph. My question is should I pull it and have them check the balance or just try reclocking it? The car is a full MM suspension car so just reclocking it is a bitch with the torque arm in the way. I just don't want to clock it three times to find that the vibration is still there. I would not think just replacing the U-joints would throw it out of balance but one never knows.
