DESCRIPTION AND OPERATION
Rear Suspension
WARNING: All vehicles are equipped with gas pressurized shock absorbers which will
extend unassisted. Do not apply heat or flame to the shock absorbers during removal or
component servicing. Failure to follow these instructions can result in personal injury.
CAUTION: Suspension fasteners are critical parts because they affect performance of vital
components and systems and their failure can result in major service expense. A new part with
the same part number must be installed if installation becomes necessary. If substitution is
necessary, the part must be of the same finish and property class. Torque values must be used
as specified during reassembly to make sure of correct retention of these parts.
The rear suspension consists of the following components:
zrear spring (4460)
z rear shock absorber (18125)
z rear upper suspension arm and bushings (5500)
„common LH and RH
z rear lower suspension arm and bushings (5A649)
„common LH and RH
z rear stabilizer bar (5A772) (4.6 2V- equipped models only)
z axle drive line vibration dampers (4.6 2V- equipped models only)
