REMOVAL & INSTALLATION
If one spring must be replaced, the other should be replaced also. If the car has a stabilizer bar, the bar must be removed first.
- Raise and support the car at the rear crossmember, while supporting the axle with a jack.
- Lower the axle until the shocks are fully extended.
- Place a jack under the lower arm pivot bolt. Remove the pivot bolt and nut. Carefully and slowly lower the arm until the spring load is relieved.
- Remove the spring and insulators.
- To install, tape the insulator in place in the frame, and place the lower insulator in place on the arm. Install the internal damper in the spring.
- Position the spring in place and slowly raise the jack under the lower arm. Install the pivot bolt and nut, with the nut facing outwards. Do not tighten the nut.
- Raise the axle to curb height, and tighten the lower arm pivot bolt to 70-100 ft. lbs. (95-136 Nm) for 1979-81 cars, 90-100 ft. lbs. (122-136 Nm) for 1982-86 cars, or 70-100 ft. lbs. (95-136 Nm) for 1987-88 cars.
- Install the stabilizer bar, if removed, and tighten the fasteners to 15-20 ft. lbs. (20-27 Nm) for 1979-81 cars, 45-50 ft. lbs. (61-68 Nm) for 1982-86 cars, or 33-51 ft. lbs. (45-69 Nm) for 1987-88 cars.
- Remove the crossmember stands and lower the car.
