Alignment: Service and Repair
CAMBERBefore 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 three times. Always release the bumper in the down position.
The wheel camber angle is preset. This angle is not adjustable and cannot be altered.
CASTER
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 three times. Always release the bumper in the down position.
Check the caster of the front axle for correct angle. Be sure the axle is not bent or twisted. Road test the vehicle and observe the steering wheel return-to-center position. Low caster will cause poor steering wheel returnability.
During the road test, turn the vehicle to both the left and right. If the steering wheel returns to the center position unassisted, the caster angle is correct. However, if steering wheel does not return toward the center position unassisted, a low caster angle is probable.
Caster can be adjusted by installing a cam bolts and rotating the cams on the lower suspension arm.
NOTE: Changing caster angle will also change the front propeller shaft angle. The propeller shaft angle has priority over caster.
TOE POSITION
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 three times. Always release the bumper in the down position.
NOTE: The wheel toe position adjustment is the final adjustment. This adjustment must be performed with the engine running, if the vehicle is equipped with power steering.
1. Start the engine and turn wheels both ways before straightening the steering wheel. Center and secure the steering wheel.
2. Loosen the adjustment sleeve clamp bolts.
3. Adjust the right wheel toe position with the drag link. Turn the sleeve until the right wheel is at the correct positive TOE-IN position. Position the clamp bolts as shown and tighten to 49 Nm (36 ft. lbs.). Make sure the toe setting does not change during clamp tightening.
4. Adjust the left wheel toe position with the tie rod. Turn the sleeve until the left wheel is at the same TOE-IN position as the right wheel. Position the clamp bolts as shown and tighten to 27 Nm (20 ft. lbs.). Make sure the toe setting does not change during clamp tightening.
5. Verify the right toe specifications and turn off the engine.
