CORP.REF.NO: 233303R
DATE:
June 1992
SECTION:
3, 3C
SUBJECT:
FRONT STRUT BEARINGS MAY CAUSE MEMORY STEER - REPLACE UPPER STRUT MOUNTING BEARING
MODELS/YEARS:
1992 ACHIEVA
CONDITION:
On a smooth, flat road the vehicle may exhibit a type of lead or pull condition directly following the completion of a turning maneuver. When the
steering wheel is returned to a straight ahead position, the vehicle may tend to lead or pull in the last direction turned. This is known as "Memory Steer".
This condition is always noted as being in the same direction as the last turning maneuver.
CAUSE:
The upper strut mounting bearing may be sticking or binding which may cause a preload on the strut. This preload may cause the vehicle to move in the
last direction turned, thus causing "Memory Steer".
CORRECTION:
Replace the upper strut mounting bearing with new bearing P/N 908552 (currently available from GMSPO) by using the following procedure:
1.
Refer to Dealer Technical Bulletin, 92-T-20, for proper diagnosis. If memory steer is found, proceed to the next step.
2.
Remove both strut assemblies from the car, refer to SECTION 3C in the service manual.
3.
Disassemble strut, refer to SECTION 3C in the service manual.
4.
Remove upper strut bearing by pressing the old bearing out of the top mount assembly.
5.
Install new bearing into the top mount assembly using hand pressure.
6.
Reassemble strut.
7.
Install strut on car.
Note:
When installing strut on car, do not interchange the top strut bolt and brake hose bracket bolt. The short bolt must go on the top of the strut.
8.
Check front wheel alignment, adjust if necessary.
