OK guys, I'm looking for a little insight to a recent potential problem with my car. Yesterday, I installed the Dorman 33mm front sway bar on my car, and now I have a peculiar vibration issue. After putting the bar on, there is a vibration in the driveline when the car is in drive, and I accelerate at low speeds. It will also vibrate if I stall the car up while stopped, and the vibration increases with the revs. It does not, however, vibrate when in reverse, while rolling or stopped in neutral, or at speeds above ~20 m.p.h. Has anybody else had this problem or know what may be causing it?
