The pinion angle of the front axle can be adjusted by the use of adjustment cams in the lower suspension arms. The primary function for the cams is to adjust the caster angle for the alignment of the front suspension. When using the cams to adjust the pinion angle, make sure that both cams are moved equally. After the pinion angle is adjusted, the front suspension alignment should be checked to ensure that side-to-side caster angles variance is with-in the acceptable range. Having the correct pinion angle does have priority over having the preferred caster angle.
A cam kit is available to be installed in the rear axle lower suspension arms in order to provide adjustablity of the pinion angle. Follow the procedures supplied with the kit in order to ensure a safe installation.
