CASTER & CAMBER, ADJUST

Independent Front Suspension

Front suspension height must be checked and corrected as necessary prior to checking wheel alignment.
1. Remove all foreign material from exposed threads of cam adjusting bolt nuts or pivot bar adjusting bolt nuts.
2. Record initial camber and caster readings before loosening cam bolt nuts or pivot bar bolt nuts.
3. On vehicles using cam bolts, the camber and caster is adjusted by loosening the cam bolt nuts and turning the cam bolts as necessary until the desired setting is obtained. On vehicles using pivot bars, tool C-4581 or equivalent is required to adjust caster and camber. When performing adjustments, the camber settings should be held as close as possible to the "desired" setting, and the caster setting should be held as nearly equal as possible on both wheels.

No adjustment is provided for camber. If camber is not within specifications, axle or steering knuckle is bent and should be replaced.
Caster may be adjusted by inserting a wedge between the spring and axle. To increase caster insert wedge so that the thick part faces rear of vehicle. To decrease caster insert wedge so that the thick end is toward front of vehicle.




TOE-IN, ADJUST

With the front wheels in straight ahead position, loosen the clamps at each end of both adjusting tubes. Adjust toe-in by turning the tie rod sleeve which will "center" the steering wheel spokes. If the steering wheel was centered, make the toe-in adjustment by turning both sleeves an equal amount. Position sleeve clamps so ends do not align in the sleeve slot.
