DESCRIPTION AND OPERATION
SUSPENSION COMPONENTS
The front suspension is a link/coil design (Fig. 1).
This suspension is use on Left Hand Drive (LHD)
and Right Hand Drive (RHD) vehicles. The suspen-
sion is comprised of:
• Drive axle (4WD), tube axle (2WD)
• Dual-action shock absorbers
• Coil springs
• Upper and lower suspension arms
• Stabilizer bar
• Track bar
• Jounce bumpers
CAUTION: Components attached with a nut and
cotter 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/
urethane 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.
