Camber variations may be caused by one
of the following conditions:
• | Wear at the wheel bearings |
• | Wear at the steering knuckle bushings |
Refer to
Wheel Alignment Specifications
for camber specifications.
Important: Before checking the camber, inspect the king pin wear. Complete the
following steps:
- Raise the front of the vehicle.
- Pull the bottom of the wheel outward and measure the camber.
- Pull the top of the wheel outward and take a camber measurement
(use a camber gauge, if available).
- If a camber gage is not
available, place a square (5) against the tire and take the measurements.
- If the measurements vary by more than 15 minutes (¼
degree), adjust the wheel bearing. Refer to
Wheel Bearing Adjustment
in Front Suspension.
- Take the camber measurements again. If the measurements still
vary by more than 15 minutes (¼ degree), replace the steering
knuckle bearing and/or the bushings and the king pins. Refer to
Steering Knuckle and King Pin Replacement
.
- Inspect the wheel runout. Refer to
Abnormal or Excessive Tire Wear
. Replace the wheel if the wheel runout
is excessive.
- Place the vehicle on a level surface, with the normal weight of
the vehicle on the wheels. Take a final camber measurement.
- Note the dimension of the top measurement and the dimension of
the bottom measurement.
• | Ensure that the dimension of the bottom measurement exceeds the
dimension of the top measurement. |
• | 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, inspect the king pin
inclination. Add the camber plus the king pin 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 degrees),
(the knuckle is bent). |
• | Replace the front axle if the included angle of each knuckle end
is within the specifications, but the final camber is incorrect (the axle
center is bent). |
