Wheel Alignment Specifications & Procedures: Other Lexus GS I

FLOOR JACK

Place floor jack on vehicle support points shown. (Scheme 4)

Scheme 4

EMERGENCY JACKING

Place manufacturer-supplied jack under reinforced support points of sill between front and rear wheels. Safety stands may also be placed at these points. (Scheme 4)

HOIST

Place lift blocks under reinforced support points of sill between front and rear wheels. (Scheme 4)

Front Suspension

Measure and record camber and caster. See WHEEL ALIGNMENT SPECIFICATIONS. If adjustment is necessary, loosen adjuster cam bolts. Rotate adjuster cams as necessary. (Scheme 5) Tighten adjuster cam bolts to specification. See TORQUE SPECIFICATIONS.

Scheme 5

Rear Suspension

1. Inspect tires for wear and proper inflation. Ensure lengths of No. 1 and 2 lower suspension arms are equal by rotating adjuster cams (if necessary). (Scheme 6) Measure toe-in.
2. Measure camber of each rear wheel. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-62222-S14612822062001100400000). If camber and/or toe-in are not within specification, loosen adjuster cam bolts. Adjust by rotating adjuster cams. (Scheme 7) Tighten adjuster cam bolts to specification after adjustment. See «TORQUE SPECIFICATIONS»(ref-62222-S05985657432001100400000).

Scheme 6

Scheme 7

Caster is adjusted together with camber. See CAMBER ADJUSTMENT under WHEEL ALIGNMENT PROCEDURES.

STEERING AXIS INCLINATION

Ensure riding height and camber are correct. Measure steering axis inclination of each front wheel. See the following

1. «RIDING HEIGHT ADJUSTMENT»(ref-62222-S36756734022001100400000) .
2. «CAMBER ADJUSTMENT»(ref-62222-S34019365252001100400000) .
3. «WHEEL ALIGNMENT SPECIFICATIONS»(ref-62222-S14612822062001100400000) .

If steering axis inclination is not within specification, inspect related front suspension components. Replace any components that are worn or damaged. Steering axis inclination is not adjustable.

1. Ensure riding height, camber, steering axis inclination, and caster are correct. Ensure front wheels are in straight-ahead position. See the following: «RIDING HEIGHT ADJUSTMENT»(ref-62222-S36756734022001100400000) . «CAMBER ADJUSTMENT»(ref-62222-S34019365252001100400000) . «STEERING AXIS INCLINATION»(ref-62222-S08136325002001100400000) . «CASTER ADJUSTMENT»(ref-62222-S29131409672001100400000) .
2. Bounce both ends of vehicle several times to settle suspension. Measure toe-in. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-62222-S14612822062001100400000) . If necessary, adjust toe-in by changing length of tie rods. Length of tie rods must be equal within .06" (1.5 mm) after adjustment.

Ensure rear camber is correct. See CAMBER ADJUSTMENT under WHEEL ALIGNMENT PROCEDURES. Bounce both ends of vehicle several times to settle suspension. Measure toe-in. See WHEEL ALIGNMENT SPECIFICATIONS. If toe-in is not within specification, loosen adjuster cam bolts. Adjust toe-in by turning adjuster cams. (Scheme 7) Tighten adjuster cam bolts to specification. See TORQUE SPECIFICATIONS.

TOE-OUT ON TURNS

1. Ensure steering wheel is in straight-ahead position. Raise front of vehicle. Place turning radius gauges beneath front wheels. Lower front of vehicle.
2. Rotate steering wheel fully right and left, observing turning radius on both wheels. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-62222-S14612822062001100400000) . If toe-out on turns is not within specification, inspect related front suspension components. Replace any components that are worn or damaged.
