SINGLE AND DOUBLE CARDAN JOINT

cleaning solvent and a wire brush.
(2) Inspect the yokes for distortion, cracks and
worn bearing assembly bores.

ADJUSTMENTS

ADJUSTMENT AT AXLE WITH LEAF SPRINGS

Adjust the pinion shaft angle at the springs with
tapered shims (Fig. 37). Install tapered shims
between the springs and axle pad to correct the
angle.
Fig. 37 Angle Adjustment at Leaf Springs
Adjust the pinion gear angle at the lower suspen-
sion arms with shims (Fig. 38). Adding shims will
decrease the pinion gear shaft angle but will increase
the caster angle. The pinion gear shaft angle has pri-
ority over the caster angle.
