# FRONT SUSPENSION UPPER STRUT MOUNT NUT CHANGE / CORRECTION

#### MODELS AFFECTED: 1985-88 ELECTRAS 1986-88 LESABRES AND RIVIERAS, AND 1988 REATTAS

Use the following information to update the Front Suspension Section of the 1985 thru 1987 Buick Chassis Service Manuals:

The large 24mm nut that secures the upper strut mount to the front spring and strut assembly (see Figure 1) on 1988 LeSabres, Electras, Rivieras, and Reattas has been changed in production. This new design nut is the same nut that was used on some earlier production vehicles.

The old design nut, Part Number 22527148, is silver in color and has a flange on the bottom side. The new design nut, Part Number ')5526968, is gold in color and does not have a flange (See Figure 2).

If a front strut module is repaired for any reason, the upper strut mount nut must be torqued to the proper value. The 1985 thru 1987 Service Information Manuals improperly stated the torque for the strut mount nut. The non-flanged design nut should be torqued to 75 N.m (55 ft. lbs.). Proper torque on the flanged design nut is 100 N.m (75 ft. lbs.).

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.
