Front Caster and Camber Adjustment
Front Caster and Camber Adjustment
Important: Caster measurements are now relative to ground.
1. 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.
Important: Before adjusting the caster and camber angles, jounce the front bumper 3 times to allow the vehicle to return to normal height. Measure and adjust the caster and the camber with the vehicle at curb height. The front suspension Z dimension is indicated in Trim Heights.
2. For an accurate reading, do not push or pull on the tires during the alignment process.
3. Determine the caster angle (2).
4. Determine the positive camber (2) or negative camber (3) angle.
5. Remove the pinned adjusting cam insert. Do not reinstall the cam insert.
6. Loosen the upper control arm cam adjustment bolts.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
7. Adjust the caster and the camber angle by turning the cam bolts until the specifications have been met. 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 lb ft).
8. Verify that the caster and the camber are still within specifications. Refer to Wheel Alignment Specifications . When the caster and camber are within specifications, adjust the toe.
