Front Camber and Caster

FRONT CAMBER AND CASTER





The camber and caster angles are adjusted using adjustment cams. There is one cam located on each upper control arm pivot bolt. Correct camber and caster specifications are obtained by simultaneously rotating the front and rear adjustment cams until the upper control arm is correctly positioned.
Set front camber and caster at each front wheel using the following procedure.

CAUTION: Prior to any cam bolt rotation, the cam bolt nuts must be loosened. This must be done to allow upper control arm mounting brackets to be spread allowing free movement of bushings. If not done, serious bending of bracket, weld breakage of cam retainer, fracturing of free cam and cam bolt shank or thread damage can occur.

1. Loosen the nuts on the upper control arm pivot (cam) bolts as necessary. There are two cams. One is located on each pivot bolt for the upper control arm.
2. To adjust front camber, rotate both pivot (cam) bolts an equal amount either inward or outward. The upper control arm and ball joint are moved inward or outward thus changing the camber angle of the knuckle.
3. To adjust front caster, rotate both pivot (cam) bolts in opposite directions of each other. The upper control arm and ball joint are moved forward or rearward thus changing the caster angle of the knuckle.

NOTE: When tightening the upper control arm pivot (cam) bolts using Adapter, Special Tool 8106, the mechanical advantage of a torque wrench is increased by a factor of 1.5. For this reason, the actual torque wrench reading or setting will be lower then the torque specification. Example: If the torque specified is 108 Nm (80 ft. lbs.), the torque wrench reading or setting should be 72 Nm (53 ft. lbs.).








4. After the caster and camber has been set to the preferred specification, tighten the upper control arm pivot (cam) bolt and nuts to a torque of 108 Nm (80 ft. lbs.). The upper control arm front and rear cam bolt nuts are tightened and torqued with assistance of Torque Wrench Adapter, Special Tool 8106, as shown.
5. Proceed with the procedure to set front toe.
