[SCARRY]

BLAS has a good point if there is clearance between the rack bar and pinion gear then the wheels are free to move due to the free play. The adjustment is there to push the rack bar against the pinion so that there is no play. Normaly there is a spring or a spring washer to help with maintaining the lash. Not sure if ours have that.
One other thing that I found on my car is the I Shaft joint to the steering column shaft was not tight. The bolt was tight but I could move the shaft in the splined U Joint. I did tighten mine up and I do not have the issues that are mentioned. I also have my origonal BFG's and the original balance. The car is a 2003 SPF.
