TRACK BAR
DESCRIPTION
The bar is attached to a frame rail bracket with a
ball stud and an axle bracket with a bushing. The
bar is forged and has non replaceable isolator bush-
ing and ball stud.

movement and provides cross car location of the axle
assembly.
REMOVAL
(1) Raise and support the vehicle.
(2) Remove the cotter pin and nut from the ball
stud end at the frame rail bracket (Fig. 10).

DESCRIPTION
REAR SUSPENSION
The rear suspension is link/coil design comprised
of:
• Shock absorbers
• Coil springs
• Upper and lower suspension arms
• Stabilizer bar
• Track bar
CAUTION: Suspension components with rubber/ure-
thane bushings (except stabilizer bar) should be
tightened with the vehicle at normal ride height. It is
important to have the springs supporting the weight
of the vehicle when the fasteners are torqued. This
will maintain vehicle ride comfort and prevent pre-
mature bushing wear.
