Suspension Spring ( Coil / Leaf ): All Technical Service Bulletins
Suspension - Rear Spring Noise
Bulletin 86-3-13
Date
Jan. '87
Ref. No. 86-192-3
SUBJECT:
REAR SPRING NOISE
MODELS AFFECTED: 1986 FRONT WHEEL DRIVE LESABRE
There have been some owner comments, on subject models, of a banging type rear suspension noise noticeable on rough roads. This noise was due to
rear spring coil contact and was corrected on 1987 front wheel drive LeSabres by new designed springs. To use the 1987 rear springs on a 1986
complaint vehicle, determine the code identification of the springs on the vehicle and obtain a 1987 service spring which has the same "Rate" and comes
closest to the "Load" of these springs.
FIGURE 1 - 1986 FRONT WHEEL DRIVE LESABRE PRODUCTION REAR SPRING USAGE
FIGURE 2 - 1987 FRONT WHEEL DRIVE LESABRE SERVICE REAR SPRING CHART
Figure 1 lists the "Rate" and "Load" of the 1986 front wheel drive LeSabres production springs. Figure 2 lists the currently released 1987 LeSabre
service springs.
For example, if a 1986 vehicle has code MAS rear springs, the 1987 service springs, Code RRD, Part No. 25530346 should be ordered from GMSPO.
