NOTICE:
All rear suspension fasteners are an important attaching part in that it could affect the performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of the same part
number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of lesser quality or
substitute design. Torque values must be used as specified during reassembly to assure proper retention of parts.
NOTICE:
Never attempt to heat, quench or straighten any rear suspension part. Replace it with a new part or damage
to the part may result.

The rear suspension is a MacPherson Strut
design. This combination strut and spring adapts to
the rear wheel drive. The lower control arms pivot
from the engine cradle. The cradle has isolation
mounts to the body and conventional rubber bushings
are used for the lower control arm pivots. The upper
end of the strut is insulated by a rubber mount.
N O T I C E :
Boot protector J 28712 should be
installed whenever servicing rear suspension
components, in order to prevent damage to the
drive axle boot.
