SHUDDER DURING VEHICLE MOVEMENT FROM A STANDSTILL - HIGH FRONT SUSPENSION RIDE HEIGHTS
FORD:
1992-94 TEMPO
LINCOLN-MERCURY:
1992-94 TOPAZ
ISSUE:
Shudder during acceleration from a standstill may be caused by high front suspension ride heights. The vehicle's appearance (attitude) may be high in the
front.
ACTION:
A procedure has been developed for determining vehicle ride heights, along with specifications for fender opening-to-wheel center measurements. If
service is required, use the following procedure to determine the vehicle's ride height and, if necessary, make appropriate spring replacements. Refer to
the 1992/94 Tempo/Topaz Service Manual, Section 4-01, for service details.
1.
Park the vehicle on a level surface with a full tank of gas. If less than a full tank is available, use the adjustment factors shown in the Fuel Fill
Adjustment Factor Chart.
2.
Set tires to decal pressure.
3.
Neutralize the vehicle's suspension system.
a.
Push on the roof rail above the driver's door laterally so as to cause the vehicle to roll.
b.
Use about five (5) or six (6) pushes to provide sufficient roll to settle the vehicle out in a neutralized state.
4.
Find the fender opening-to-wheel height dimension.
a.
Measure vertically from the wheel center to the bottom edge of the fender opening.
b.
The specification for this height is 13.96" +/- 0.25" (355 mm +/- 6.3 mm).
NOTE:
SPRING LOAD STEPS PROVIDE A 0.25" (6.3 MM) FENDER-TO-WHEEL HEIGHT CHANGE. FOR EXAMPLE, A ONE LOAD CHANGE WILL
PROVIDE A 0.25" (6.3 MM) CHANGE AND A TWO LOAD CHANGE WILL PROVIDE A 0.5" (12.6 MM) HEIGHT CHANGE.
