what do i have to adjust to fix this problem?

Make sure all of the steering linkages are set to the same length, and *important* attached in the same holes on the left and right sides.

Also check to make sure all of the suspension adjustments are the same on both sides, this also goes for the rear. Shock preload, and where you mount the shocks top and bottom should be the same.

After all that, you may have a befective, or weak servo. Or possibly, one wheel/tire is way out of balance.

What vehicle is this? Pics?
