Caster and Camber

Caster and camber adjustment is possible with service adjusters available in 1/2-degree, 1-degree and 1-1/2-degree increments. One adjuster is used to adjust both caster and camber depending on its orientation.
1. Measure vehicle caster and camber.
^ Refer to the alignment charts to determine if the vehicle is within specifications.
^ Note difference between the actual measurements and the specification. This information will be used to select the correct service adjuster.





2. If adjustment is necessary, determine the amount of caster/camber in the adjuster installed in the vehicle.
^ Production adjusters have the amounts of caster and camber stamped in the top of the adjuster.
^ The first number is the amount of caster, the second number is the amount of camber in degrees if the adjuster is installed in the right axle position.
^ If the adjuster is in the left axle, the caster number is the opposite sign of the number shown.
^ For example, a positive amount in the right axle is a negative amount in the left axle, and a negative amount in the right axle is a positive in the left position.








3. Refer to the above chart. Select a new service adjuster and its orientation in the axle to obtain the optimum caster/camber. Note that the caster change or camber change required to obtain the optimum settings must be added to amounts of caster/camber in the old or production adjuster.

For example, if caster and camber must be reduced 1.0 degree, and camber increased +0.75 degree at the left wheel, and the existing adjuster has +0.25 degree caster as installed, select the 1.0 degree service adjuster and orient the slot 225 degrees from the straight-ahead position.

4. Raise the vehicle and support with jackstands.
5. Remove the front wheel.








6. Loosen the pinch bolt at the upper ball joint and pry the adjuster out of the axle with the blade of a screwdriver. If required, use Pitman Arm Puller T64P-3590-F to remove the adjuster.
7. Install the new service adjuster. Orient the slot as specified in the chart.

NOTE: The assembly plant sometimes builds vehicles with adjusters that are not zero-degree type to control alignment. The table shows the alignment changes that will occur if the vehicle was originally built with zero-degree adjusters. Always check to see which adjuster has been installed (and its orientation) before making changes.

8. Tighten the pinch bolt to 68-92 Nm (50-68 ft. lbs.).
9. Install front wheel and lower vehicle.
10. Check alignment: If not optimal caster/camber setting, additional adjustment of the rotation of the adjuster may be required to obtain optimal alignment settings.
11. Once optimal caster/camber is achieved, reset front toe to specifications and check alignment.
^ In all cases, select the adjuster and orientation that will bring the alignment closest to the optimal settings.

12. Check alignment and reset toe to specification.
