REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5, 6, 7, 8 and 91970-78 Pick-Up-2WD
The coil springs are retained under considerable pressure. They can exert enough force when released to cause serious injury. Exercise extreme caution when disassembling the strut for coil spring removal.
- Remove the hub cap and loosen the lug nuts.
- Raise the front of the truck and support the front suspension crossmember with jackstands.
- Remove the lug nuts and the wheel.
- Remove the stabilizer bar connecting bolts and remove the bracket parts, being careful to note their removal sequence in order to aid in installation.
- Remove the tie rod cotter pin and nut. Use a puller to remove the end of the tie rod from the knuckle arm.
- Remove the shock absorber. Detach the brake hose.
- Raise the lower control arm using a jack, so that the arm is free of the steering knuckle.
- Loosen the ball joint attachment nut and remove the ball joint.
- Slowly lower the jack underneath the control arm.
If the jack is lowered too quickly, the spring could suddenly release, causing damage and/or injury.
- Remove the coil spring and its insulator from beneath the truck.
- Inspect the coil spring, its insulator, and bumper for cracks, wear or damage. Replace parts as necessary.
- A coil spring compressor should be used to install the spring, rather than the method for removing it.
- Tighten the suspension components to the following specifications:
Lower control arm:
1970-75: 51-65 ft. lbs.1976-78: 33-43 ft. lbs.
Ball joint: 87-123 ft.lbs.
