It seems whenever I am accelerating and going over a bump the engine revs higher. It seems like it looses traction when it goes over the bumps so it causes it to rev up quicker. I am wondering if this happenes to other people. It only happenes when I hit bumps and accelerate. The rear shocks were replaced not too long ago and the front strut assembly was just done as well as nerw ball joints. Anyone think it may be ball joints?
