1. It is important that the camber (vertical tilt) angle be the same for both front wheels.
2. The camber angle should be measured with accurate wheel alignment equipment.
The acceptable range is + 1/2° to + 1 1/2°.
Refer to the Specifications chart.
A satisfactory test for assurance can be made by road testing the vehicle and observing the steering wheel return-to-center position.
Note: Before road testing, check and correct the tire inflation pressures. Inflate both of the front tires with exactly the same pressure.
During the road test, make vehicle turns to both the left and right. If the steering wheel returns toward the center position unassisted, the caster angle is
correct. However, if the steering wheel does not return toward the center position unassisted, an incorrect caster angle is probable.
1. The caster angle is factory preset at positive two degrees ( + 2°).
The acceptable range is + 1/2° to + 3 1/2°.
2. The caster angle should be measured with accurate wheel alignment equipment.
3. Caster angle can be adjusted by installing tapered shims between the front axle pads and the spring brackets.
The caster angle should be adjusted as near as possible to the preferred angle.
4. Record the caster measurement before removing the original shims from the spring pads.
5. The caster should be the same at both sides of the vehicle.
