SUBJECT: FRONT SUSPENSION UPPER STRUT MOUNT NUT CHANGE

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

FIGURE 1 - STRUT TO STRUT MOUNT NUT:

The large 24 mm 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 FAD DeVilles and Fleetwoods.

FIGURE 2 - STRUT NUTS:

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.).
