Front Toe Adjustment


Toe is the turning in or out of wheels. The actual amount of toe is normally .078 inch (2 mm). The purpose of toe is to ensure parallel rolling of wheels. Excessive toe-in or toe-out may increase tire wear. Toe also serves to offset small deflections of the suspension which occurs when vehicle is moving.


Fig. 2 Adjusting Toe-in:






Toe-in is adjusted by altering tie rod length. To perform adjustment, loosen small end boot clamps and slide from the boot. Loosen right and left tie rod end locknuts, then turn both tie rods, Fig. 2, the same amount to bring toe-in within specifications. Ensure right and left tie rods are equal in length, then tighten locknuts. When adjustment is complete, ensure boots are not twisted.
