# SERVICE MANUAL UPDATE REVISED TOE ADJUSTMENT TORQUE

#### Models Affected: 1988-89 LeMANS

#### SERVICE MANUAL UPDATE

Page 3A-4 replaces the current page in the 1988-89 LeMans Service Manual with a revised Toe Adjustment Torque.

To get an accurate caster reading and establish standing curb height, the turnplates or slider plates must move freely. Take them apart at least once a year to be cleaned and lubricated. Replace badly worn tumplates.

#### Important

---------

The following conditions must be met for correct FRONT and REAR wheel alignment:

1. The tread on all tires must be uniform, and tires must be in good condition.

2. Tire pressures must be equal.

3. Each rim must be checked and must be in satisfactory condition.

4. Load each of the front seats of this vehicle with 70 Kg (154 lbs.)

5. Fuel tank should be half filled.

6. Rock the vehicle several times to stabilize the springs (also stabilize springs if vehicle was previously raised.)

o When using an alignment unit with a turntable that records no lateral forces, the vehicle must first be rolled rearward 1 meter (1 yard) and then returned to its initial position.

7. The method of checking alignment will vary depending upon the type of equipment used. The instructions furnished by the equipment manufacturer should be followed.

#### FRONT TOE ADJUSTMENT

#### Adjust:

------

Toe is adjusted by changing the steering tie rod length. Loosen right and left tie rod end clamp bolts (B), then turn right and left tie rod adjusters (A) to align toe to specification. In this adjustment, right and left tie rods must be equal in length.

#### Tighten:

-------

o Clamp bolts to 20 N-m (15 lbs. ft.)

#### REAR TOE CHECK

Rear toe is not adjustable. If the toe deviates from that specified in the "Wheel Alignment Specification Chart", the rear axle assembly and the wheel spindle are to be checked for possible damage. Repair or replace the contributing component.

#### FRONT CAMBER AND CASTER CHECK

Front camber and caster are not adj ustable. If the camber or caster deviates from that specified in the "Wheel Alignment Specification Chart", locate and replace or repair the damaged, loose, bent, dented or worn suspension part(s). If the problem is body related, the body should be repaired according to the proper specifications.

To prevent an incorrect reading of camber or caster, jounce the bumper three times before inspection.

#### REAR CAMBER CHECK

Rear camber cannot be adjusted. Should rear camber be found out of specification, locate the cause and correct. If damaged, loose, bent, dented or worn suspension parts are found, they should be repaired or replaced. If the problem is body related, the body should be repaired according to the proper specifications.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
