STEERING WHEEL OFF CENTER POSSIBLE CAUSES

MODELS AFFECTED: 1986 RIVIERAS

Some early production 1986 Rivieras may have steering wheels that are off center. This condition may be caused by either misadjusted toe-in or improper frame to body alignment. Follow the listed service procedure to repair this condition.

INSPECTION

1. Raise vehicle.

2. View the two alignment holes through the slotted hole between the number 2 and 3 frame insulator positions. See Figure 1.

3. If the alignment holes line up the frame is properly positioned, as illustrated in Figure 1, repair the "steering wheel off center" condition by adjusting toe in.

4. If the alignment holes do not line up, refer to the repair procedure in this bulletin.

REPAIR PROCEURE

1. If using a body contact hoist support frame with jack stands. If using a suspension contact hoist support body with jack stands.

2. Remove left and right #1 insulator covers.

3. Loosen #1, #2 and #3 frame insulator bolts on both the left and right side of the frame.

4. If using a body contact hoist raise vehicle slightly to unload insulators. If using a suspension contact hoist lower hoist slightly to unload insulators.

5. Insert dowel pins, on both the left and right side, through the slotted hole and two alignment holes see Figure 2.

6. Move the dowel pins so the two alignment holes line up when viewed from the botton, see Figure 1.

7. Tighten left hand #2 frame insulator bolt to 100 N.m (74 ft. lbs.).

8. Tighten left hand #1 frame insulator bolt to 100 N.m (74 ft. lbs.).

9. Tighten remaining frame insulators bolts to 100 N.m (74 ft. lbs.), (order optional).

For warranty purposes, use labor operation T6138 at 1.4 hours to adjust frame position, add .3 hours if necessary to file struts to adjust caster.

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.
