# FRONT SUSPENSION UPPER STRUT MOUNT NUT CHANGE / CORRECTION

FRONT SUSPENSION UPPER STRUT MOUNT NUT CHANGE

#### VEHICLES AFFECTED: 1985-1988 "C" AND "H" CARS, 1986-1988 ----------------- "E" AND "K" CARS, 1987-1988 "V" CAR The large 24mm nut that secures the upper strut mount to the front spring and strut assembly (see Figure 1) on 1988 "E, K and V" cars has been changed in production. This new design nut is the same nut that is used on 1985-1988 "C and H" cars. The old design nut, P/N 22527148, is silver in color and has a flange on the bottom side. The new design nut, P/N 25526968, 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 through 1987 FWD DeVille/Fleetwood and 1986 and 1987 Eldorado and Seville 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.
