to the road surface. While being able to twist as one wheel moves vertically with respect to the other.

Roll resistance is provided partly by the axle's resistance to twist. But primarily by a torque tube or rod (depending on the suspension option called for) running through the channel and attached rigidly to its end plates by welding. Because the torque tube/rod is an integral part of the axle assembly, it cannot be individually replaced.

The spindles are bolted to the axle end (spindle mounting) plates and can be individually replaced if required. Rear wheel alignment changes require the use of shims between the spindle and axle end plates.

SHOCK ABSORBERS

REMOVAL

(1)Raise vehicle, see Hoisting, Group 0.

(2)Support axle and remove wheel and tire assem-

bly.

(3)If equipped with air shocks, disconnect air lines.

(4)Remove upper and lower shock absorber fasteners, remove shock absorbers (Fig. 2).

Fig. 2 Remove/Install Shock Absorber Fasteners

INSPECTION

Inspect for evidence of fluid leakage from upper end of reservoir. (Actual leakage will be a stream of fluid running down and leaking off lower end). Slight seepage is not unusual and will not effect performance.

Ä

INSTALLATION

(1)Position shock absorber on car. Install upper and lower fasteners loosely to hold shock absorber in place.

(2)Tighten upper fastener to 61 NIm (45 ft. lbs.) torque. Connect air line, if so equipped.

(3)Install wheel and tire assembly, tighten wheel stud nuts to 129 NIm (95 ft. lbs.) torque. Lower vehicle to ground.

(4)With suspension supporting the weight of the

vehicle. Tighten lower shock absorber fastener to 54 NIm (40 ft. lbs.) torque.

COIL SPRINGS AND JOUNCE BUMPER

REMOVAL

(1)Lift vehicle see hoisting Group 0.

(2)Support axle assembly and remove both lower shock absorber attaching bolts.

(3)Lower axle assembly until spring and spring upper isolator can be removed (Fig. 3). Do not stretch brake hose.

(4)Remove two screws holding cup to rail (Fig. 1). Remove assembly.

Fig. 3 Coil Spring & Jounce Bumper

INSTALLATION

(1)Position cup to rail. Install and tighten attaching bolts to 8 NIm (70 in. lbs.) torque.

(2)Install isolator over jounce bumper and install spring.

(3)Raise axle and loosely assemble both shock absorber to axle mounting bolts. Remove axle support and lower vehicle.

(4)With suspension supporting the weight of the

vehicle. Tighten both shock absorber attaching bolts to 61 NIm (45 ft. lbs.) torque.
