Camber variations may be caused by one of the following conditions:

    • Wear at the wheel bearings
    • Wear at the steering knuckle bushings
    • Bent steering knuckle
    • Bent axle center

Refer to Wheel Alignment Specifications for camber specifications.

Important: Before checking the camber, inspect the king pin wear. Complete the following steps:

  1. Raise the front of the vehicle.
  2. Use a camber gauge. If a camber gauge is not available, the readings can still be taken.
  3. Place a square (5) against the tire as shown.

  4. Object Number: 340702  Size: SH
  5. Pull the top of the wheel outward and take the camber measurements (1, 4, or 6).
  6. Pull the bottom of the wheel outward and take the camber measurements (1, 4 or 6).
  7. If the measurements vary by more than 15 minutes (¼ degree), adjust the wheel bearing. Refer to Wheel Bearing Adjustment .
  8. Take the camber measurements again. If the measurements still vary by more than 15 minutes (¼ degree), replace the kingpin bearings and/or bushings. Refer to Steering Knuckle and King Pin Replacement in Front Suspension.
  9. Inspect the wheel runout. Replace the wheel if the wheel runout is excessive.
  10. Place the vehicle on a level surface, with the normal weight of the vehicle on the wheels. Take a final camber measurement.
  11. Note the dimension of the top measurement and the dimension of the bottom measurement.
  12. Ensure that the dimension of the bottom measurement exceeds the dimension of the top measurement.
  13. Verify that the camber dimensions of the right wheel do not vary by more than 2.4 mm (0.0938 in) from the camber dimensions of the left wheel. If the final camber measurement is incorrect, then either the steering knuckle or the axle center is bent. In order to determine which part is bent, check the kingpin inclination.
  14. Add the camber plus the kingpin inclination dimensions. This measurement is the included angle of the steering knuckle. Replace the steering knuckle if the included angle of the steering knuckle varies from specifications by more than 30 minutes (½ degree). Straighten the axle center if the included angle of each knuckle end is within the specifications, but the final camber is incorrect.
