Camber Adjustment -Rear
NOTE:
Air suspension vehicles must be at trim ride height prior to measuring or adjusting the rear camber or toe. For additional information, refer to VEHICLE DYNAMIC - 4 WHEEL
.
- Measure and record the LH rear and RH rear camber angles.
- Compare the recorded camber angles to the specifications. Refer to Figure.
- Determine desired camber adjustment (subtract the specified camber angle from the measured camber angle).
- Remove the rear wheel. For additional information, refer to WHEELS & TIRES .
- Mark a scribe line on the upper arm-to-wheel knuckle bolt head and upper arm.
- Use CAMBER ADJUSTMENT CHART to determine the camber adjustment required.
- Obtained by subtracting the specified camber angle from the measure camber angle.

- Position the upper arm-to-knuckle bolt in the upper arm slot as required to adjust camber angle to the value obtained in step 6.
- Tighten the upper arm-to-knuckle nut.
- Install the wheel and tire assembly. For additional information, refer to WHEELS & TIRES .
- Using the alignment equipment, verify the camber adjustment.
- Check and if necessary, adjust the rear toe. For additional information, refer to REAR TOE ADJUSTMENT .
NOTE:
Support the vehicle at the lower arm to ease the wheel knuckle movement in the upper arm slot.
