On all I-Mark (RWD) and early model Impulse, camber angle can be increased approximately 1 degree by removing the upper ball joint, rotating it 1 / 2 turn and reinstalling it with the cut-off portion of the upper flange on the inboard side of the control arm. On late Impulse models, camber is not adjustable. Replace parts as necessary to correct alignment. On FWD I-Mark, Impulse and Stylus, the camber cannot be adjusted because it is preset at the factory.Trucks
The camber angle can be adjusted by means of the camber shims installed in position between the chassis frame and fulcrum pins.
On RWD I-Mark caster angle can be changed by realigning the washers located between the legs of the upper control arm. Washers come in two sizes 3mm and 9mm. On FWD I-Mark, Impulse and Stylus caster angle is built into the front end and is not itself adjustable.
The caster angle can be adjusted by varying the length of the strut rod for the 2WD P'up. The caster angle can be adjusted by means of caster shims installed in position between the frame and fulcrum pins. Adding to one side or another change the caster angle. Adjust camber after adjusting caster.
Toe in is controlled by adjusting the tie rod. To adjust the toe in setting loosen the nuts at the tie rod end. Rotate the rod as required to adjust the toe in. Retighten the cover and locknuts, check that the rubber bellows is not twisted on vehicles equipped with rack and pinion steering systems. For all specifications, see the Alignment Specs in this section.
The vehicle height can be adjusted by turning the torsion bar adjusting bolts to achieve the desired vehicle height.
