Ark, you were right, it was t he diff. Took it out, re-cleaned it and sanded the plates. Now it works like a charm and the car was dialed. Ran into another problem.
When I accelerate, the car torques/veers to the right.....half way down the straight, it goes straight....i tried to trim it our upon the start of the straight and it does go straight, but at the end of the straight it pulls left....ALOT.....could this be one of my shocks???
