PRE-ALIGNMENT INFORMATION
Note. Prior to performing wheel alignment, perform visual and mechanical inspection of wheels, tires and suspension components. See the PRE-ALIGNMENT CHECKS article in this section. For basic wheel alignment theory, refer to the WHEEL ALIGNMENT THEORY/OPERATION article in the GENERAL INFORMATION section.
ORDER OF ALIGNMENT
To ensure accurate alignment, align wheels in the following order
- Rear Camber
- Rear Toe-In
- Front Caster
- Front Camber
- Front Toe-In
CAMBER ADJUSTMENT (REAR)
Loosen bolts securing front and rear ends of lower control arm to frame. (Scheme 2) Move lower control arm inward or outward as necessary to adjust camber. Tighten bolts to specification. See TORQUE SPECIFICATIONS.
Scheme 2
TOE-IN ADJUSTMENT (REAR)
Loosen toe link bolt. (Scheme 3) Move wheel inward or outward as necessary until toe-in is as specified. See ALIGNMENT SPECIFICATIONS table.
Tighten bolts to specification. See TORQUE SPECIFICATIONS .
Scheme 3
CASTER ADJUSTMENT
Support vehicle by its wheels (suspension loaded). Remove nuts and washers from front strut mounting tower. Move top of strut forward and/or rearward as necessary to adjust caster. Tighten nuts to specification. See TORQUE SPECIFICATIONS .
CAMBER ADJUSTMENT (FRONT)
Loosen nuts on bolts securing strut to steering knuckle. Tighten or loosen camber adjusting bolt as necessary to adjust camber to specification. See ALIGNMENT SPECIFICATIONS table. While holding wheel in position, tighten nuts to specification. See TORQUE SPECIFICATIONS .
TOE-IN ADJUSTMENT (FRONT)
Loosen tie rod end lock nut. (Scheme 4) Loosen clamp securing dust boot to inner tie rod. Rotate inner tie rod until toe-in is as specified. See ALIGNMENT SPECIFICATIONS table. Tighten lock nut to specification. See TORQUE SPECIFICATIONS. Ensure steering gear dust boot is straight after adjustment. Tighten dust boot clamp.
