i have a 2003 Sport Edition 2WD and my problem was it pulls either left or right when driving 50 mph and higher. so this weekend, did a wheel alignment at Royal Moore in Beaverton, Oregon. it's a 2WD so how did they align the 4 wheels?
with vehicles that have a solid rear axle (4runner), there is no such thing as 4 wheel alignment. If they charged you extra for a '4 wheel alignment', get your money back.
4Runners have live axle rear suspensions. That means a 4-wheel alignment CANNOT be performed on a 4Runner because there are no alignment adjustments on the rear. The only thing that can be done is a thrust angle alignment. That means the front wheels are aligned according to the thrust angle of the rear wheels. This kind of alingment is usually less expensive than a 4-wheel alignment because of the fact that it's quicker and easier since you only actually align the front end, not the rear.
