I know this has been hashed over before, but I'm hoping someone else has had this and has a new idea. I just put a set of Cobra R's and Kumho 255x45 17' on. As best as I can tell, the tires are balanced properly and there is no runnout in the wheels. Starting at about 70MPH, I get a slight vibration under power that gets worse at cruise and dramatically worse under deceleration. If I just kick it into neutral, it stops. I get NO vibration at all under 70. I checked the flange bolts on the diff, they are tight. The U-joints don't have any visible play either (The car has about 95k on it). There is a little slack in my diff, I get a audible "clank" when rotating the shaft back and forth, but I've had that since the 3:73's were installed. Could the U-joints be bad and I just couldn't feel it with the other tires and stock wheels? I'm tempted to order a Dynotech driveshaft and be done with it.
Thanks in advance for any help!
