1. MAKE FOLLOWING CHECKS AND CORRECT ANY PROBLEMS

(a) Check the tires for wear and proper inflation.

Cold tire inflation pressure: kg/cm* (psi, kPa)

MEASURE VEHICLE HEIGHT

Vehicle height

If height of the vehicle is not as specified, try to level the vehicle by shaking it down. If the height of the vehicle is still not correct, check for bad springs and worn or loose suspension parts.

3. INSTALL WHEEL ALIGNMENT EQUIPMENT

Follow the specific instructions of the equipment manufacturer.

225/60 HR 14

(b) Check the rear wheel bearings for looseness.

(c) Check wheel runout.

Lateral runout: Less than 1.0 mm (0.039 in.)

(d) Check the rear suspension for looseness.

(e) Check that the rear absorbers work properly by the standard bounce test.

MEASURE VEHICLE HEIGHT

Vehicle height mm (in.)

4. INSPECT CAMBER

Inspect the camber with a wheel alignment tester. Inspection standard: —10' ± 45' Adjustment standard: -10' ± 30' Left-right error 20'

If camber is out of tolerance, inspect and replace damaged or worn rear suspension parts.

Celica Supra Differential

5. ADJUST TOE-IN

(a) Measure the distance between each disc wheel and the differential carrier cover bolt of the suspension member and confirm that both are the same.

Mk2 Supra Differential

(b) If the distances are not the same but within 5 mm (0.20 in.), adjust with the toe-in adjusting bolt.

Mk2 Supra Suspension

(c) Move the vehicle forward a few meters with the fro« wheels in the straight-ahead position on a level^ place.

(d) Mark on each center of rear tread and measure the distance between marks of the right and left tires.

(e) Advance the vehicle till the marks on the rear sides of the tires come to the measuring heights of the gau$ on the front sides.

NOTE: Toe-in should be measured at the same point on the tire and at the same level.

Inspection standard

Adjustment standard

Toe-in

0 ± 2 mm (0±0.08 in.)

0 ± 1 mm (0 ± 0.04 in.)

(f) If not within specification, turn the left and right adjusting bolts an equal amount to adjust.

NOTE: The toe-in will change about 1 mm (0.04 in.) with each graduation of the cam (one side).

(g) Tighten the bolts after adjustment the toe-in. Torque: 1,325 kg-cm (96 ft-lb, 130 N m)

Sideslip Toe

6. INSPECT SIDE SLIP WITH SIDE SLIP TESTER

Side slip limit: Less than 3.0 mm per meter

If the side slip exceeds this limit, the toe-in or camber may not be correct.
