SERVICE ADJUSTMENT PROCEDURES

FRONT WHEEL ALIGNMENT

When using a wheel alignment tester to inspect front wheel alignment, always position the car on a level surface and the front wheels in the straight ahead position Prior to inspection make sure that the front suspension and steering system are in normal operating condition and that wheels and tires are free of deflection and tires inflated to specification.

Toe-in

Toe-in (B-A or angle CX) is adjusted by turning the tie rod buckles Toe-in on the left front wheel can be reduced by turn- ing tie rod toward the rear of the car Toe-in change achieved by turning the tie rods for the right and left wheels simultaneously the same amount is as follows:

WHEEL AND TIRE

WHEEL ROTATION

1 Rotate the tires in the patterns illustrated.

CAUTION

Temporary spare tire should not used in the wheel rotation.

Simple method to Improve Load, Pull and Wander

1 If the steering wheel pulls to one side, perform the tire rotation

by following procedures.

(a) Interchange the front right and left tires, and perform the

road test in order to confirm the vehicle stability.

(b) If the steering wheel pulls to opposite side, interchange the

front and rear tires, and perform the road test.

(c) If the steering wheel still pulls to one side, interchange the

front right and left tires again, and perform the road test.

(d) If the steering wheel pulls to opposite side of step (3), replace the front wheels with new ones.

INSTRUCTIONS FOR ALUMINUM TYPE WHEELS

1 Aluminum is vulnerable to alkalies If a vehicle washing gent gas been used, or salt from sea water or road chemicals has adhered, wash the vehicle as soon as possible After wash- ing the vehicle, apply body or wheel wax to the aluminum type wheels to prevent corrosion.

deter-2 When cleaning the vehicle with steam, do not direct steam onto the aluminum type wheels.

When tightening nuts for aluminum type wheels, particularly observe the following:

(a) Clean the hub surface of aluminum type wheels.

(b) After finger-tightening wheel nuts, tighten them to ifications.

spec-(c) Do not use an impact wrench or push the wrench by foot to tighten the wheel nuts.

(d) Do not apply oil to the threaded portions.

TIRE CHAINS AND SNOW TIRES

1 Use tire chains only on front wheels Do not use tire chains on rear wheels.

2 When using snow tires, use them on all four wheels for maneuverability and safety.

CAUTION

Do not use tire chains on the P175/70 R13 tires.

Interference between the tire chains and the front wheel house can occur if chains are used on the P175/70 R13 tires.
