Wheel Alignment Specifications & Procedures Chevrolet Lumina I

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

1. Rear Camber
2. Rrear Toe-In
3. Front Caster
4. Front Camber
5. Front Toe-In

CAMBER ADJUSTMENT (REAR)

1. Raise and support vehicle. Remove rear wheel. On Cutlass Supreme and Regal, remove auxiliary spring. On all models, remove strut. Put strut in a vise. File the following bolt hole at lower end of strut to make it oblong. (Scheme 1) Lower bolt hole (Cutlass Supreme, Grand Prix and Regal) Upper bolt hole (Lumina and Monte Carlo)
2. Install strut, but DO NOT fully tighten strut mounting bolts at steering knuckle. Lower vehicle. Adjust camber to specification. See «ALIGNMENT SPECIFICATIONS»(/chevrolet/lumina/i-1989-2001/remont/wheel-alignment/#wheel-alignment-specifications-procedures) table. Tighten bolts to specification. See «TORQUE SPECIFICATIONS»(/chevrolet/lumina/i-1989-2001/remont/wheel-alignment/#wheel-alignment-specifications-procedures__torque-specifications).

Scheme 1

TOE-IN ADJUSTMENT (REAR)

1. Adjust left and right sides separately. Lubricate threads of Turnbuckle Adjuster (J-38118). Install turnbuckle adjuster between hole in rear suspension rod and hole in jackstand pad. (Scheme 2) Ensure equal number of threads are exposed on both sides of turnbuckle. Hand-tighten turnbuckle adjuster.
2. Loosen nut on bolt securing rear suspension rod to crossmember at least 4 turns. Rotate turnbuckle adjuster as necessary until rear toe-in is as specified. See «ALIGNMENT SPECIFICATIONS»(/chevrolet/lumina/i-1989-2001/remont/wheel-alignment/#wheel-alignment-specifications-procedures) table. Tighten rear suspension rod nut at crossmember to specification. See «TORQUE SPECIFICATIONS»(/chevrolet/lumina/i-1989-2001/remont/wheel-alignment/#wheel-alignment-specifications-procedures__torque-specifications).

Scheme 2

CASTER ADJUSTMENT

Caster is not adjustable. If caster is not as specified, check for worn or damaged suspension or body parts. Repair or replace as necessary.

CAMBER ADJUSTMENT (FRONT)

1. Loosen 3 strut cover attaching nuts. Remove strut cover. Lift front of vehicle enough to allow strut attaching studs to clear mounting holes. Cover top of strut to keep metal shavings from damaging strut. Using Template (J-36892) as a guide, file the 3 holes as necessary to allow for camber adjustment. (Scheme 3)
2. Paint all exposed surfaces with rust-preventive paint or primer. Lower front of vehicle while aligning studs into holes. Install, but DO NOT tighten, 3 strut cover attaching nuts. Set camber to proper specification. See «ALIGNMENT SPECIFICATIONS»(/chevrolet/lumina/i-1989-2001/remont/wheel-alignment/#wheel-alignment-specifications-procedures) table. Tighten strut cover attaching nuts to specification. See «TORQUE SPECIFICATIONS»(/chevrolet/lumina/i-1989-2001/remont/wheel-alignment/#wheel-alignment-specifications-procedures__torque-specifications).

Scheme 3

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.
