The adjusting screw is on the rack housing and adjusts pinion gear-to-rack clearance. Turning the screw clockwise tightens the clearance. Turn the adjusting screw no more than 20 degrees and test drive the vehicle after each adjustment. If the adjustment does not improve steering response or feel, return the screw to its original position and look for worn or damaged steering or suspension parts.
