REMOVAL & INSTALLATION
See Figures 1 and 21986-89 Eldorado and Seville
- Raise the car and support it securely by the frame. Remove the tire and wheel from the side on which you wish to draw out the spring.
- If you are working on the left side, and the car has Electronic Level Control (ELC), disconnect the ELC height sensor link.
- If the car has a stabilizer bar, disconnect the mounting bolt at the strut.
- Reinstall two wheel nuts opposite each other to hold the rotor onto the hub/bearing assembly.
- Remove and suspend the brake caliper.
- Loosen but DO NOT REMOVE the knuckle pivot bolt on the outboard end of the control arm.
- Remove the strut rod cap, mounting nut, retainer, and upper insulator. Then, compress the strut by hand and remove the lower insulator.
- Remove the inner control arm nuts. Support the knuckle and control arm with a floorjack, then remove the inner control arm bolts. Remove the control arm, knuckle, strut, hub/bearing, and rotor as an assembly.
- Using a jackstand capable of suspending the entire weight of the car, suspend the outer end of the spring securely.
Make sure the jackstand is square under the spring so that the stand will not shift or personal injury could result.
- Gradually and cautiously lower the car until its weight compresses the spring so there is no weight on the spring retainer. Then, remove the retainer mounting bolts, the retainer, and the lower insulator from that side of the car. Raise the car slowly until the jackstand is free of downward pressure from the spring and remove it.
- Draw the spring out of the rear suspension. Remove the upper spring insulators as necessary.
- Install any insulators that required replacement. Upper outboard insulators must be installed so that the molded arrow points toward the vehicle centerline. Torque the center and outboard insulator nuts to 21 ft. lbs. (28 Nm).
- Position the spring into the crossmember. Make sure the outboard and center insulator locating bands are centered on the insulators.
- Follow Step 9 and the caution above to support the outer end of the spring with a jackstand. Then, carefully and gradually lower the car until its weight will permit easy installation of the spring retainer.
- Install the lower insulator and spring retainer and torque the bolts to 21 ft. lbs. (28 Nm). Raise the vehicle carefully and when the spring is clear, remove the jackstand.
- Position the assembled control arm, knuckle, strut, hub and bearing and rotor assembly into the crossmember assembly and install the inner control arm bolts and nuts JUST HAND TIGHT!
- Install the lower strut insulator and position the strut rod into the suspension support assembly.
- Install the upper strut insulator, retainer, and nut. Torque the upper strut nut to 65 ft. lbs. (88 Nm), the knuckle pivot bolt to 59 ft. lbs. (80 Nm) and the inner control arm bolts to 66 ft. lbs. (89 Nm).
- Install the strut rod cap. Install the stabilizer mounting bolt if the car has a stabilizer bar. Torque this bolt to 43 ft. lbs. (58 Nm).
- Remove the two wheel nuts retaining the brake rotor. Install the remaining parts in reverse of the removal procedure. Have the rear end alignment checked and adjusted, if necessary.
