Front Caster and Camber Adjustment

Front Caster and Camber Adjustment

1. Determine the angle of the vehicle frame relative to ground. The caster values must be compensated for the measured frame angle. To determine the frame angle use a digital protractor or equivalent, or measure both sides of the frame and take an average from those measurements.

Frame angle is positive when higher in the rear.:

2. If frame angle is positive, add the average frame angle to the caster reading obtained in step 6 of this procedure when making adjustments.

Frame angle is negative when lower in the rear.:

3. If frame angle is negative, subtract the average frame angle from the caster reading obtained in step 6 of this procedure when making adjustments.

Important:
- Before adjusting the caster and camber angles, jounce the front bumper three times to allow the vehicle to return to normal height.
- The caster and camber adjustments are made by rotating the offset cam bolt and the cam in the slotted frame bracket in order to reposition the control arm.

4. Measure and adjust the caster and the camber with the vehicle at curb height.
The front suspension Z dimension is indicated under Ride/Trim Height Specifications.

5. For an accurate reading, do not push or pull on the tires during the alignment process.

7. Determine the positive camber or negative camber angle.





8. Remove the pinned adjusting cam insert. Do not reinstall the cam insert.
9. Loosen the upper control arm cam adjustment bolts.






9. Adjust the caster and the camber angle by turning the cam bolts until the specifications have been met.


10. When the adjustments are complete, hold the cam bolt head in order to ensure the cam bolt position does not change while tightening the nut.

Tighten the cam nuts to 190 Nm (140 ft. lbs.).

11. Verify that the caster and the camber are still within specifications.
When the caster and camber are within specifications, adjust the toe.
