ISSUE:
The vehicle may ride low in the rear when loaded at or near GVWR. This condition is caused by poorly computed camber dimensions for
the springs.
ACTION:
Install a rear spring shim (F1TZ-5W536-A) to each rear spring. Refer to the following procedure for service details.
On 1991 vehicles only, check the part number prefix located on either the bottom side of the last spring leaf near the center bolt or on the bottom side of
the spring clip.
^
If the part number prefix is F17A, do NOT add a rear spring shim.
^
Confirm that the height and weight is as specified in the Body Builder's Specification Book and the vehicle is not overloaded.
