I am having problems getting my 1997 850 Turbo wagon aligned. After 3 tries, my local Firestone is refunding my money because the car still pulls to the right. Firestone says the wheels are within spec; however, the car still pulls. The tires are new. Firestone even tried to switch the tires around to see if a tire was causing the problem. They also looked at ball joints, etc. and everything looked OK. The car has been out of alignmnet for a while; however, prior to this it drove straight as a arrow.

Any ideas?

Thanks!!!!!!!
