It's been going on for a long time now. I replaced my U-joints and my harmonic balancer and that took away alot of the problem. I had my D/S pulled before I had even replaced the balancer and the U-joints, and there was not problem with it. Anyway I was just wondering what would be the best thing to do to remedy this problem. Any help would be greatly appreciatd. Also this problem was noticed before I had my 3.73's installed. Thanks in advance.
