REMOVAL & INSTALLATION
See Figures 1, 2 and 3
The coil springs are under a considerable amount of tension. Be extremely careful when removing or installing them; they can exert enough force to cause serious injury. Use only approved spring compressors for suspension servicing.
- Raise the front of the vehicle and support with jackstands at the frame so the control arms hang free.
- Remove the shock absorber. Disconnect the stabilizer bar at the steering knuckle.
- Support the inner end of the control arm with a floor jack.
- Raise the jack enough to take the tension off the lower control arm pivot bolts. Install the spring compressor through the spring and frame. Tighten the compressor until the lower control arm pivots bolts can be removed. Compress the spring far enough to remove the lower control arm and spring.
- Remove the lower ball joint nut and separate from the knuckle using a ball joint separator tool J-23742 or equivalent.
- Chain the spring to the lower control arm.
- Remove first the rear, then the front pivot bolt.
- Cautiously loosen the spring compressor until all spring tension is released.
- Note the way in which the spring is installed in relation to the drain holes on the control arm and remove it.
- On installation, position the spring to the control arm and raise it into place. On 1985 and later Oldsmobile models, note that the spring must be positioned so that the end of the coil covers all or part of one inspection/drain hole in the lower control arm, and the other hole must be only partly covered.
- Compress the spring far enough to install the front and rear pivot bolts.
- Install the pivot bolts and torque the nuts to 100 ft. lbs. (136 Nm) on models built through 1984. On 1985-90 models, torque the bolts to 90 ft. lbs. (122 Nm).
- Install the lower ball joint to the knuckle, torque the nut to 85 ft. lbs. (112 Nm) and install a new cotter pin.
- Replace the shock absorber and stabilizer bar.
