DESCRIPTION
FRONT SUSPENSION
The front suspension is a link/coil design com-
prised of:
• Shock absorbers
• Jounce Bumper
• Coil springs
• Upper and lower suspension arms
• Stabilizer bar
• Track bar
CAUTION: Components attached with a nut and cot-
ter pin must be torqued to specification. Then if the
slot in the nut does not line up with the cotter pin
hole, tighten nut until it is aligned. Never loosen the
nut to align the cotter pin hole.
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. If
springs are not at their normal ride position, vehicle
ride comfort could be affected and premature bush-
ing wear may occur.
STANDARD PROCEDURE - LUBRICATION
Periodic lubrication of the suspension system is
required. Refer to Lubrication And Maintenance for
the recommended maintenance schedule.
The following component must be lubricated:
• Track bar
