RAM 1500 Van V8-5.9L VIN Z (1998)
Alignment: Service and Repair
GENERAL INFORMATION
The front wheel alignment angles should be set to preferred specifications. This will prevent abnormal tire tread wear.
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.
CAMBER AND CASTER
Camber and caster angle adjustments involve repositioning the upper suspension arm pivot bar. Alignment adjustments are accomplished by
changing the position of the pivot bar.
Adjuster Tool 8199, or equivalent is used to adjust the camber and caster angles.
Tools Attached To Frame
1. Clamp the tool on the upper suspension arm frame bracket. Use the two clamp bolts to attach the tool to the bracket.
2. With the adjustment tools installed, loosen both upper suspension arm bolts completely.
3. Tighten or loosen the tool adjustment bolts to move the upper suspension arm inward or outward to obtain the proper camber and caster
angles.
Caster: Move the rear position of the pivot bar in or out. This will change the caster angle significantly and camber angle only slightly. To retain
the camber while adjusting caster, move the rear pivot bar in or out. Move the forward pivot very slightly in the opposite direction.
NOTE: For example, to increase a positive caster angle move the rear position of the pivot bar inward. Move the front of pivot bar outward until
the original camber angle is obtained.
Camber: Move the forward position of the pivot bar in or out. This will change the camber angle significantly and caster angle only slightly. The
camber angle should be adjusted to the service specifications. Tighten the pivot bar bolts to 298 Nm (220 ft. lbs.).
