GM 25710009
Spring Seat, Rear Driver Side

Vehicle suspension work starts by elevating the vehicle and placing supports underneath. Begin by removing the wheel and tire followed by inserting a jack stand under the Control Arm. You must first disconnect the automatic level control air tube from the shock absorber and unscrew the lower shock absorber retaining bolts. Separate the adjustment link from the lower Control Arm by removing its retaining nut then using the universal steering linkage puller (J24319-B) tool. Using the support assembly to position the lower Control Arm slowly and using pry tools to remove the lower Coil Spring Insulator while extracting the coil spring. Squeeze the tool to remove the upper Coil Spring Insulator. To install parts, first position the upper Coil Spring Insulator retainer inside the vehicle body after which you should install the coil spring followed by the lower insulator and confirm the insulator rests within the lower Control Arm. After raising the lower Control Arm you must attach two shock bolts to it before adding the lower shock absorber retaining bolts which need to be tightened to 24 nm (18 ft. Lbs.). Tighten the adjustment link-retaining nut onto the lower Control Arm until torque reaches 50 nm (36 ft. Lbs.). Fit the automatic level control air tube to the shock absorber before reinstalling the tire and wheel assembly when lowering the vehicle.

The first step to replace coil spring insulators consists of raising and supporting the vehicle. Start the replacement by lifting the wheel off the tire before placing your jack stand under the lower Control Arm. First disconnect the automatic level control air tube from the shock absorber before removing the lower shock absorber retaining bolts. The universal steering linkage puller (J 24319-B) will detach the adjustment link from the lower Control Arm after removing the adjustment link retaining nut. Drop the lower Control Arm onto the support assembly while slowly lowering it before using a pry tool to remove the lower Coil Spring Insulator and coil spring. To extract the upper Coil Spring Insulator you must pull downward. When installing components place the upper Coil Spring Insulator retainer into the vehicle body before mounting both the coil spring and lower insulator while making sure the insulator fully rests inside the lower Control Arm. Lift the lower Control Arm into position then bolt two shock fasteners to the Control Arm. Next install the lower shock absorber retaining bolts and tighten them to 24 nm (18 ft. Lbs.). Secure the adjustment link to the lower Control Arm by installing its retaining nut while tightening it to 50 nm (36 ft. Lbs.). To complete the repair place the automatic level control air tube onto the shock absorber before reinstalling the tire and wheel and dropping the vehicle to the ground.

Vehicle raising and suspension follow as the initial step to replace coil spring insulators. Begin by taking out the wheel and tire and after that support the lower Control Arm through using a jack stand. Remove the lower shock absorber retaining bolts while extracting the automatic level control air tube attachment from the shock absorber. Next follow these steps: take off the adjustment link retaining nut then use universal steering linkage puller (J 24319-B) to split the adjustment link from the lower Control Arm. While lowering the support assembly you can pry underneath the lower Coil Spring Insulator to remove the coil spring with its insulator. You should pull down to remove the upper Coil Spring Insulator. Start by inserting the vehicle body upper Coil Spring Insulator retainer before you add the coil spring and lower insulator below the lower Control Arm. Make sure that the insulator properly rests in the lower Control Arm. Insert the two shock bolts into the Control Arm before fastening the lower shock absorber retaining bolts to 24 nm (18 ft. Lbs.). Fasten the adjustment link to the lower Control Arm by adjusting the retaining nut to 50 nm (36 ft. Lbs.). Reconnect the automatic level control air tube to the shock absorber then install the tire and wheel before lowering the vehicle.

Remove the coil from the vehicle using the Universal Steering Linkage Puller (J 24319-B).

Install the Automatic Level Control air tube to the shock absorber, reinstall the tire and wheel, and lower the vehicle.

Pull downward to detach the upper coil spring insulator.

Install the shock absorber lower retaining bolts, tightening them to 24 Nm (18 ft. lbs.).

Tighten it to 30 N.m (22 lb ft) plus 180 degrees.
