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.
- Use a camber gauge. If a camber gauge is not available, the readings
can still be taken.
- Place a square (5) against the tire as shown.
- Pull the top of the wheel outward
and take the camber measurements (1, 4, or 6).
- Pull the bottom of the wheel outward and take the camber measurements
(1, 4 or 6).
- If the measurements vary by more than 15 minutes (¼ degree),
adjust the wheel bearing. Refer to
Wheel Bearing Adjustment
.
- 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.
- Inspect the wheel runout. 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, check the kingpin inclination.
- 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.
