Front Caster and Camber Adjustment RWD
Important: Before you adjust caster and camber angles, raise and release the front
bumper. Do this twice in order to allow the vehicle to return to a normal
height. Refer to
Wheel Alignment Specifications
in Suspension Wheel Alignment.
- Make adjustments to the caster and the camber by inserting shims
between the upper control arm shaft and the frame bracket. Add shims or subtract
shims or transfer shims in order to change the readings.
- To adjust the caster and the camber, loosen the upper control
arm shaft-to-frame nuts (1). Add shims or remove shims (2) as required. Tighten
the nuts. Check the toe-in after you change the caster and the camber.
- Caster--Transfer
the shims from front to rear, or from rear to front. The transfer of one
shim from the rear bolt to the front bolt decreases positive caster.
- Camber--Change the
shims at the front and the rear of the cross shaft. Add an equal number of
shims at the front and the rear of the cross shaft. This decreases positive
camber.
- A normal shim pack will leave at least two threads of the bolt
exposed beyond the nut (1). The difference between the front shim pack and
the rear shim pack must not exceed 10 mm (0.40 in). If you
cannot meet these requirements, check for damage to the control arms and
to related parts.
- Tighten the nut on the thinner shim pack first. This improves
the shaft-to-frame clamping force. This also improves torque retention.
Front Caster and Camber Adjustment 4WD
Important: Before adjusting the caster angle and camber angle, raise and release
the front bumper. Do this twice in order to allow the vehicle to return to
a normal height. Refer to
Wheel Alignment Specifications
in Suspension Wheel Alignment .
Use the cams on the upper
control arm frame attaching bolts to adjust the caster and the camber.
To adjust the caster and the camber, loosen the upper control arm-to-frame
attaching nuts. Rotate the cam by rotating the bolt head.
• | Caster--To increase positive caster, move the front cam lobe
inboard and move the rear cam lobe outboard. |
• | Camber--To increase positive camber, move the front and the
rear cam lobes inboard. |
Tighten the nuts after you select the proper cam position. Refer to Fastener Tightening Specifications
