Toe Setting
Toe is the difference between tire centerline-to-centerline distances as viewed from the front of the
vehicle. This is adjustable by loosening the cross tube clamps and turning the tube. Each end is threaded

and it gets shorter, moving the tires in or out depending on the adjustment needed. Cross tube clamps
must be re-tightened when adjustment is completed.
