FRONT SUSPENSION UPPER STRUT MOUNT NUT CHANGE / CORRECTION

MODELS AFFECTED: 1985-1988 DE VILLES AND FLEETWOODS 1986-1988 ELDORADOS AND SEVILLES 1987-1988 ALLANTES

The large 24mm nut that secures the upper strut mount to the front spring and strut assembly (see Figure 1) on 1988 Eldorados, Sevilles, and Allantes has been changed in production. This new design nut is the same nut that is used on 1985-1988 FWD DeVilles and Fleetwoods.

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.
