Front Wheel Alignment

CASTER & CAMBER

Caster and camber angles are pre-set and cannot be adjusted. If caster and/or camber are out of specifications, the cause must be found. If worn or damaged suspension components are the cause, they should be replaced. If problem is body related, the body should be repaired as needed.

Fig. 2 Adjusting toe in:

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.

STEERING ANGLE

When a tie rod or tie rod end is replaced, check toe and steering angle using suitable turning radius gauges. If steering angle is not 37-2/3° inside and 32-1/2° outside, check right and left tie rods for equal length. If tie rod length is changed to correct steering angle, reinspect toe in.
