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.
