Alignment - Recirculating Ball Steering System
All views typical.
Before each alignment reading the vehicle should be jounced (rear first, then front). Grasp each bumper at the center and jounce the vehicle up and down several times. Always release the bumper in the down position. Set the front end alignment to specifications while the vehicle is in its NORMALLY LOADED CONDITION.
CAMBER: The wheel camber angle is preset and is not adjustable.
CASTER adjustment: Check the caster of the front axle for correct angle. Be sure the axle is not bent or twisted. Road test the vehicle and make left and right turns. Observe the steering wheel return-to-center position. Low caster will cause poor steering wheel returnability.
For 2500/3500, caster can be adjusted by rotating the cams on the lower control arm. Left and right cams should be rotated in the same direction to minimize ride height changes side to side. Cross caster should not be adjusted by putting adjust cams out of phase.
