For 1990-2009 cars

### Removal Procedure

1. Block the wheels of all of the axles.
2. Support the frame using frame stands.
3. Support the axles using jack stands.
4. Drain the air pressure from the air springs.
5. Remove the following components:

• | The rebound bolt (4)

• | The locknut (1)

• | The washers

• | The spacer tube (2)

• | The rebound roller (3)

Important: The torque rods may remain in place.

6. Apply an upward force on the cross tube or lower air spring brackets using a jack or a pry bar. The tips of the main support beams will drop away from the cam surface of the spring hanger brackets.
7. Remove the following components:

• | The insulator fasteners (1, 2, 5, 6)

• | The reinforcement plates

• | The insulator pads (3)

### Installation Procedure

1. Place a new insulator pad on the spring hanger (4).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Place the retainer plate over the insulator pad.

Tighten
Tighten the 10 mm (0.375 in) hex head self- tapping screws to 34 N·m (25 lb ft).

3. Release the jack or pry bar on the cross tube or on the lower air spring brackets. Allow the main support beams to come up to the new insulator pads.
4. Install the following components:

• | The rebound rollers (3)

• | The spacers (2)

• | The rebound bolts (4)

• | The washers

• | The locknuts (1)

Tighten
Tighten the rebound bolt locknuts to 82 N·m (61 lb ft).

5. Remove the jack stands.
6. Unblock the wheels.
