Front Caster and Camber Adjustment
Important: Caster measurements or values must be compensated for the measured frame angle.
1. Caster is relative to frame, the caster values must be compensated for the measured frame angle. Determine the frame angle by positioning a digital
protractor or equivalent between the transmission support (2) and the #3 body mount (3) and obtaining a frame angle measurement.
2. Frame angle is positive when higher in the rear. Measure both sides of the frame and take an average from those measurements. Then add the
average frame angle to the caster reading when making adjustments.
3. Frame angle is negative when lower in the rear. Measure both sides of the frame and take an average from the measurements. Then subtract the
average frame angle from the caster reading when making adjustments.
