Wheel Alignment Specifications & Adjustment Procedures: Other Toyota T100 I

RIDING HEIGHT MEASUREMENT POINTS

1. Measure front riding height by subtracting height at center of lower arm adjuster cam bolt from height at center tip of spindle. (Scheme 2)
2. Measure rear riding height by subtracting height at center of front leaf spring mounting bolt from height at center line of rear axle shaft. The difference between measurements is riding height.

Scheme 2

FLOOR JACK

To raise vehicle, place floor jack under front crossmember and/or rear axle housing/differential.

EMERGENCY JACKING

Place emergency jack under front suspension crossmember and/or rear axle housing/differential.

Scheme 3

LIFTING VEHICLE WITH HOIST

On 2WD models, place lift blocks under frame side rail and rear axle housing to raise vehicle. On 4WD models, place lift blocks under front suspension crossmember and rear axle housing to raise vehicle.

TURNING ANGLE

Remove steering knuckle stopper bolt caps. On all models, turn steering wheel fully right and then left, and observe turning radius on both wheels. If turning radius is incorrect, inspect and replace any damaged or worn front suspension components. See WHEEL ALIGNMENT SPECIFICATIONS .

Front Suspension

1. Check tires for wear and improper inflation. Inspect front wheel bearings for looseness. Check wheel runout. Wheel runout should not exceed.12" (3.0 mm).
2. Inspect front suspension components for looseness. Ensure front shock absorbers work properly. Measure vehicle riding height. See «RIDING HEIGHT ADJUSTMENT»(ref-62234-S04300853632001100400000).
3. Measure camber of both front wheels. If camber is not within specification, add or remove shims on upper suspension arms on 2WD models. On 4WD models, loosen and rotate adjuster cams. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-62234-S11124823192001100400000). (Scheme 4)

Scheme 4

1. Measure riding height, camber, and steering axis inclination. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-62234-S11124823192001100400000). If adjustment is necessary, see appropriate adjustment procedure.
2. Measure caster of both front wheels. If caster is not within specification, add or remove shims on upper control arms on 2WD models. On 2WD, adjust shim thickness between front and rear locations to within.16" (4 mm). If measurement cannot be met, adjust strut rod length by adjusting strut rod nuts. (Scheme 5) On 4WD models, loosen and rotate adjuster cams. (Scheme 4)

Scheme 5

STEERING AXIS/KING PIN INCLINATION

Measure riding height and camber. See WHEEL ALIGNMENT SPECIFICATIONS . If adjustment is necessary, see appropriate adjustment procedure. Measure steering axis inclination of both front wheels. If steering axis inclination is not within specification, inspect and replace any damaged or worn front suspension components. See WHEEL ALIGNMENT SPECIFICATIONS . Steering axis/king pin inclination is not adjustable.

Measure riding height, camber, steering axis inclination, and caster. See WHEEL ALIGNMENT SPECIFICATIONS . If adjustment is necessary, see appropriate adjustment procedure. Set front wheels to straight-ahead position. Bounce both ends of vehicle several times to settle suspension. Measure toe-in. If necessary, adjust toe-in by changing length of tie rods.

Rear Suspension

Measure rear wheel toe-in. If toe-in is not within specification, inspect and replace any damaged or worn suspension components. See WHEEL ALIGNMENT SPECIFICATIONS . Rear toe-in is not adjustable.
