Alignment: Service and Repair

The front wheel alignment angles should be set to preferred specifications. This will prevent abnormal tire tread wear.
Before each alignment reading the vehicle should be jounced (rear first, then front). Grasp each bumper at the center and jounce the vehicle up and down several times. Always release the bumper in the down position.

CAMBER AND CASTER

Caster & Camber Adjustment:

Camber and caster angle adjustments involve repositioning the upper suspension arm pivot bar. Alignment adjustments are accomplished by changing the position of the pivot bar.
Adjuster Tool 8199 is used to adjust the camber and caster angles.

Tools Attached To Frame:

1. Clamp the tool on the upper suspension arm frame bracket. Use the two clamp bolts to attach the tool to the bracket.
2. With the adjustment tools installed, loosen both upper suspension arm bolts completely.
3. Tighten or loosen the tool adjustment bolts to move the upper suspension arm inward or outward to obtain the proper camber and caster angles.

CASTER: Move the rear position of the pivot bar in or out. This will change the caster angle significantly and camber angle only slightly. To retain camber move the forward pivot very slightly in the opposite direction.

NOTE: To increase a positive caster, move the rear position of the pivot bar inward. Move the front of pivot bar outward until the original camber angle is obtained.

CAMBER: Move the forward position of the pivot bar in or out. This will change the camber angle significantly and caster angle only slightly. The camber angle should be adjusted to the service specifications. Refer to the Wheel Alignment Specifications chart. Tighten the pivot bar bolts to 298 Nm (220 ft. lbs.).

TOE POSITION
The wheel toe position is the final adjustment.
1. Secure the steering wheel with the front wheels in the straight-ahead position. For power steering vehicles, start the engine before straightening the wheels.
2. Loosen the tie rod adjustment sleeve clamp bolts.

Tie Rod Adjustment:

3. Adjust the wheel toe position by rotating the tie rod adjustment sleeve.
4. Position the adjustment sleeve clamps so the ends are not located at the sleeve slot. Tighten the tie rod sleeve clamps to:
- LD: 23 Nm (17 ft. lbs.)
- HD: 35 Nm (26 ft. lbs.)

Ensure the clamp bolts are located at the underside of the sleeve.

5. Verify camber, caster and toe position.
