FRONT SUSPENSION ALIGNMENT
Adjustability:
The toe angle and spring rates are adjustable on the
front wheels.
Need for adjustment:
• Alignment should be checked whenever front
suspension or steering parts are replaced.
• Before making any front suspension adjust-
ments, check the components as described in
the FRONT SUSPENSION INSPECTION sec-
tion of this manual.
• Replace any worn components before making
and adjustment.
• Confirm that the air pressure in the tires is cor-
rect before making any front suspension adjust-
ment.
• Adjustment can provide a temporary “band-aid”
for worn components, but does not address the
core problem.

Alignment Specifications:
Alignment procedure:
1. Park the vehicle on a firm, flat, level surface.
The cargo box and seats should be empty.
2. Center the steering wheel, bounce the vehicle
and roll it back and forth to center and settle the
front suspension.
3. Begin with the camber angle: See Figure 4.13.
What is camber angle?:
Camber angle is the amount that the front
wheels lean in or out when viewed from the front
of the vehicle. It is generally described in
degrees, but can be measured in inches or milli-
meters. The unit measurement can then be
translated to degrees using trigonometry.
