Replace coupler. Criss-Cross Front Tires. Radial tire lead. Rotate or replace tire as necessary. Brake pull. Repair brake as necessary. Ride height. Measure and adjust ride height. Camber and caster angle adjustments involve changing the position of the lower control arm with the slots in the frame brackets to move the lower control arm inwards or outwards for proper adjustment.
This can be achieved by using a long pry bar with a curved tip and inserting the pry bar into the lower control arm frame brackets and prying inwards or outwards.
NOTE: Camber and caster adjustments must be made at the lower control arm Do not use the upper control arm for Camber and Caster adjustments. NOTE: When the lower control arm pivot bolts are loosened the lower control arm will normally go outwards automatically with the weight of the vehicle.
CASTER Moving the rear position of the lower control arm at the frame in or out, will change the caster angle significantly and camber angle only slightly. To maintain the camber angle while adjusting caster, move the rear of the lower control arm in or out. Then move the front of the lower control arm slightly in the opposite direction.
This will change the camber angle signif- icantly and caster angle slightly. Start the engine and turn wheels both ways before straightening the wheels.
Secure the steering wheel with the front wheels in the straight-ahead position. Loosen the tie rod jam nuts 3. NOTE: Each front wheel should be adjusted for one-half of the total toe position specification. This will ensure the steering wheel will be cen- tered when the wheels are positioned straight- ahead.
Adjust the wheel toe position by turning the inner tie rod 4 as necessary. Verify the specifications. Turn off engine. The wheel toe position adjustment is the final adjust- ment. If springs are not at their normal ride position, vehicle ride comfort could be affected and pre- mature bushing wear may occur.
The front suspension is designed to allow each wheel to adapt to different road surfaces independently. The wheels are mounted to hub bearings on the steering knuckle spindles. The double-row hub bearings are sealed and lubri- cated for life. The steering knuckles turn pivot on ball joints integral to the outboard portion of the upper control arms and pressed into the lower steering knuckle.
The ball joints are lubricated for life. Raise and support the vehicle. Remove the front splash shield. Remove the two stabilizer barretainer bracket bolts 2. Remove the bushing clamp 2. Remove the stabilizer bar bushing 3.
NOTE: Extreme pressure lubrication must be used on the threaded portions of the tool. This will increase the longevity of the tool and insure proper operation during the removal and installa- tion process. Press the bushing out using special tools CF Press 1 , —1 driver 4 and —2 Receiver 2 from the lower control arm 3. Install the stabilizer bar bushing 3 to the bar 1. Install the stabilizer bar bushing reatainer bracket 2 bolts and tighten the two mounting bolts.
Install the front splash shield. Lower the vehicle. Install the new clevis bracket bushing 3 into the lower control arm 5 using tools CF Press 1 , —3 driver 2 , —4 Depth gauge 4 the depth gauge will automatically set the depth of the bushing 3 in the control arm 5.
This unit assembly combines the front wheel mounting hub flange and the front wheel bearing into a one piece unit. Remove the wheel and tire assembly. Support the caliper, Do not let the caliper hang by the hose. Remove the wheel speed sensor nut 2. Remove the 3 hub bearing mounting bolts from the back of the steering knuckle. Remove hub bearing 3 from the steering knuckle. Install the hub bearing 3 to the knuckle.
Install the wheel speed sensor nut 2. Remove the support and lower the vehicle. The knuckle also has machined mounting locations for the front brake calipers and hub bearing. Steering linkage attached to the knuckle allows the vehicle to be steered. Remove the tire and wheel assembly. Damage to the brake hose will result. Provide a suitable support to hang the caliper securely.
Remove the brake caliper 1. Remove the caliper adapter 1. Remove the o-ring 2 and discard then remove disc brake rotor 1. Remove the wheel speed sensor 2. Remove the axle shaft nut. Remove the outer tie rod end retaining nut. Seperate the outer tie rod end 3 from the steer- ing knuckle using special tool 5.
Remove the lower ball joint nut. Seperate the lower ball joint from the knuckle 1 using tool C—A 2. Remove the upper ball joint nut. Seperate the upper ball joint 2 from the knuckle 3 using tool 1. Remove the knuckle 3 from the vehicle. Install the knuckle 1 to the vehicle. Install the lower ball joint into the knuckle. Install the lower ball joint nut. Install the upper ball joint 2 into the knuckle 3 5. Install the upper ball joint nut 4.
Install the outer tie rod end to the steering knuckle. Install the axle shaft nut. Install the wheel speed sensor 2. Install the disc brake rotor 1. Install the caliper adapter 1. Install the tire and wheel assembly. Raise the front of the vehicle. Place safety floor stands under both lower control arms as far outboard as pos- sible. Lower the vehicle to allow the stands to support some or all of the vehicle weight.
Mount a dial indicator solidly to the topside of the lower control arm and then zero the dial indicator. Position the indicator plunger against the bottom surface of the steering knuckle.
NOTE: The dial indicator plunger must be perpendicular to the machined surface of the steering knuckle. Position a pry bar under the tire assembly. Pry upwards on the tire assembly. If the travel exceeds 0. Separate the upper ball joint 2 from the knuckle 3 using special tool 1. Separate the lower ball joint 3 from the steering knuckle 1 using special tool 2.
Move the halfshaft to the side and support the halfshaft out of the way 4X4 only. Chisel out the ball joint stakes. Install the ball joint 4 into the control arm 3 and press in using special tools CF press 1 , —1 Driver 5 and —2 Receiver 2. Stake the ball joint flange in four evenly spaced places around the ball joint flange, using a chisel and hammer.
Remove the support for the halfshaft and install into position 4X4 only. If Equipped. The arms mount to the cradle bracket and the knuckle. The arm and bushings provide location and react to loads from the road. Remove the steering knuckle 3. Remove the shock clevis bracket 2 from the lower control arm. Remove the nut and bolt from the front of the lower control arm. Remove the rear bolts and flag nuts from the lower control arm. Remove the lower control arm from the vehicle.
Position the lower suspension arm into the frame rail bracket. The bottom of the shocks are bolted to the lower control arm.
The standard shocks have conventional twin tube construction and are low pressure gas charged. Gas charg- ing prevents cavitation during rough road operation. Remove the air box cover and air intake hose. Disconnect the cruise control servo electrical connector. Remove the coolant reservoir mounting bolt and move the coolant reservoir off to the side. Remove the four upper shock mounting nuts 1. Remove the tire. Remove the two brake caliper adapter bolts. Support the brake caliper adaptor and caliper.
Do not allow the caliper to hang by the brake hose. Remove the disc brake rotor. Remove the lower clevis bolt 2 at the lower con- trol arm. Remove the lower stabilizer bolt 3 at the lower control arm. Remove the shock from the vehicle. Remove the 3 PDC bracket nuts 1. Move the PDC 1 off to the side to access the four upper shock mount nuts 2.
Remove the four upper shock mount nuts 2. Remove the shock 3 from the vehicle. Install the shock assembly 3 to the vehicle. Install the coolant reservoir bolt. Reconnect the cruise control servo wiring connector. The information contained in this service manual has been prepared for the professional automotive technician involved in daily repair operations.
