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
- Ffront Toe-In
CAMBER ADJUSTMENT (REAR)
Loosen nuts on 2 bolts securing strut to steering knuckle. Install Camber Adjuster (J-29862). (Scheme 2) Rotate bolt on camber adjuster until camber is as specified. See ALIGNMENT SPECIFICATIONS.
Tighten nuts to specification. See TORQUE SPECIFICATIONS .
Scheme 2
TOE-IN ADJUSTMENT (REAR)
Loosen lock nut on tie rod. (Scheme 2) Rotate inner tie rod as necessary until full toe-out position is obtained, then rotate inner tie rod until rear toe-in is as specified. See ALIGNMENT SPECIFICATIONS.
Tighten lock nut to specification. See TORQUE SPECIFICATIONS .
CASTER ADJUSTMENT
- With vehicle on ground (suspension loaded), remove nuts securing strut upper mount to body at each strut tower. (Scheme 3) Raise front of vehicle until strut studs have cleared holes.
- Drill 11/32" holes at each strut stud hole, then file excess material between holes to create an elongated slot. Lower vehicle to install strut into tower. Adjust caster to specification. See «ALIGNMENT SPECIFICATIONS»(/buick/lesabre/vii-1992-1999/remont/wheel-alignment/#wheel-alignment-specifications-procedures). Tighten nuts to specification. See «TORQUE SPECIFICATIONS»(/buick/lesabre/vii-1992-1999/remont/wheel-alignment/#wheel-alignment-specifications-procedures__torque-specifications).
Scheme 3
CAMBER ADJUSTMENT (FRONT)
Loosen nuts on 2 bolts securing strut to steering knuckle. (Scheme 4) Install Camber Adjuster (J-29862). Rotate bolt on camber adjuster until camber is as specified. See ALIGNMENT SPECIFICATIONS.
Tighten nuts to specification. See TORQUE SPECIFICATIONS .
Scheme 4
TOE-IN ADJUSTMENT (FRONT)
Loosen tie rod end lock nut. (Scheme 5) Loosen clamp securing dust boot to inner tie rod. Rotate inner tie rod until toe-in is as specified. See ALIGNMENT SPECIFICATIONS. Tighten lock nut to specification. See TORQUE SPECIFICATIONS. Ensure steering gear dust boot is straight after adjustment. Tighten dust boot clamp.
