I got new ball joints, tie rods, etc last summer for my w123, I have noticed that it has been pulling to the right more. When i switched to the 17s, I notice it a lot more. I adjusted the Steering box, and it helped a little, but my car has a lot of miles on it, and the steering box does have about 2 inches of play one way, then 2 inches the other tangentally to the steering wheel. I noticed that my rear sway bar links are shot. Could this be causing the problem? Should I upgrade to a bigger sway bar while Im fixing those? The TD has the biggest sway bar right?
Thanks for your help
