84ford10Article No. 84-17-7
VEHICLE CURB ATTITUDE LOW IN REAR WHEN LOADED
LINCOLN-MERCURY 1983 LINCOLN/MARK VI; 1984 LINCOLN TOWN CAR WITH STANDARD SUSPENSION
If a vehicle appears "low in the rear" when loaded, replace the standard duty rear springs with heavy duty
trailer tow springs. Refer to Section 14-32 of the Shop Manual for procedure.
The installation of a trailer tow spring in place of a standard duty spring of equivalent load will result in more ground clearance when loaded, while the unloaded vehicle heights/ground clearances will remain the same.
FIGURE 7:
Identify the rear springs currently in the vehicle from the door VIN plate (Figure 7), or tag on the springs and select the equivalent load trailer tow spring from the following chart.
