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.
