Alignment: Service and Repair

CASTER & CAMBER ADJUSTMENT (EXC. TORONADO)

Fig. 1 Caster & camber adjustments. Exc. Toronado:

Caster and camber angles can be adjusted by adding, subtracting or transferring shims between upper control arm shaft and frame bracket. Caster is adjusted by transferring shims from front to rear or rear to front, whereas camber is adjusted by changing shims at both the front and rear of the shaft.

Caster and camber can be adjusted in one operation as follows:
1. Loosen upper control arm shaft-to-frame attaching nuts.
2. Add, subtract or transfer shims as needed, Fig. 1.

3. Tighten upper control arm shaft-to-frame attaching nuts.
Tighten nut on thinner shim pack first.

4. Ensure shim pack has at least two bolt threads exposed past the nut and that difference between front and rear shim packs does not exceed 0.40 inch.
If these requirements are not met after adjusting to specifications, check suspension and steering components for damage and repair as necessary.


TOE-IN ADJUSTMENT

Fig. 3 Tie rod clamp & sleeve positioning. Exc. Toronado:

1. Loosen clamp bolts at each end of tie rod adjustable sleeves.
2. Set steering wheel in straight-ahead position and turn tie rods as necessary until toe-in is within specifications.
3. After adjustment is complete, ensure threads exposed on each end of sleeve are equal and tie rod end housings are at right angles to steering arm.
4. Position tie rod clamps and sleeves as shown, Fig. 3 then torque nuts to 15 ft. lbs.
