Just to add to TJ, get a wheel balance done can make a heee-yooge difference to how the car feels. Yeah, it's expensive, and while many will say that you save on wear and tear of other components, reduced fuel consumption etc, it really does make a substantial handling difference. Also, the last thing you need should you be involved in a prang is for the assessors to turn around and say you car was not maintained properly etc. Get it done, and see if you can feel a difference in handling...
