Camber Angle
Important: For vehicle alignment to be accurate, the shop floor must be level in every direction. The turn plates for the front wheels must rotate freely without friction, and the alignment equipment must be calibrated as directed in the alignment equipment manufacturers maintenance procedures and intervals. Western Star dealers must have proof of this calibration history.
Compare the camber angles with those shown in the appropriate table in Alignment Specifications in this section. Differences between the measurements taken in the step above and the angles in the table are caused by damaged (bent) axle components.
Incorrect camber angles could be caused by damage in one or more of the following front axle components: the knuckle pin, the knuckle pin bushings, the axle spindle, or the axle beam. Replace twisted or otherwise damaged components. Don't try to straighten twisted or bent components; replace them with new components. If a bent or twisted front axle knuckle pin, axle spindle, or axle beam has been straightened, the axle warranty will be voided.
