REMOVAL & INSTALLATION
See Figures 1, 2 and 3
A coil spring compressor should be used for safety during removal and installation. This tool can usually be rented at tool rental shops.
- Raise and support the front of the vehicle using jackstands at the frame so the control arms hang free.
- Disconnect the lower shock absorber mounting bolts and push the shock upward into the spring. If necessary for ease of tool installation, remove the upper mounting nut, then remove the shock from the vehicle.
- Disconnect the stabilizer bar.
- Support the inner end of the control arm using tool No. J-23028 and a floor jack.
- Raise the jack enough to take the tension off the lower control arm pivot bolts.
- Install a spring compressor tool for safety. If a tool is unavailable, loosely install a chain around the spring and through the lower control arm to keep the spring from suddenly releasing and flying out from the mount under pressure.
- Remove the rear pivot bolt first, then the front pivot bolt from the control arm. Note the direction which the bolts are facing for installation purposes.
- Cautiously lower the jack until all spring tension is released. If a spring compressor tool is used, the tool will keep the spring under compression.
- Note the position in which the spring is installed in relation to the drain holes in the control arm, then remove the spring from the vehicle.
- If the spring is to be replaced and it is retained by a spring compressor tool, follow the tool manufacturer's instructions to slowly release the spring tension. With the tension eased, remove the spring from the tool.
- If a spring compression tool is being used, install the new spring to the tool and carefully compress it for installation.
- Position the spring to the lower control arm as noted during removal. Make sure that at least part of 1 drain hole is uncovered once the spring is positioned. If no compressor tool is being used, chain the spring to the control arm for safety.
- Carefully raise the control arm using the jack and fixture until the spring is compressed (no tool being used) and the control arm us properly positioned.
- Install the pivot bolts in the direction noted during removal, but do not fully tighten at this time.
- Remove the chain or compressor tool, then lower and remove the jack.
- Connect the stabilizer bar. If removed, install the upper shock absorber mounting nut, then secure the bottom of the shock absorber to the control arm.
- Remove the jackstands and carefully lower the vehicle.
If there is insufficient clearance in order to access and tighten the lower control arm pivot bolts, raise and support the car on ramps. If ramps are not available, use jackstands under the control arms so the suspension is compressed.
- With the vehicle's weight supported by the suspension, tighten the control arm pivot fasteners. Tighten the bolts to 85 ft. lbs. (115 Nm) for vehicles through 1973, to 100 ft. lbs. (136 Nm) for 1974-77 vehicles or to 65 ft. lbs. (88 Nm) for 1978 and later vehicles.
