Removal
1. Locate and remove the air suspension system fuse (see chapter 12).
2. Loosen the rear wheel nuts, lift the rear of the car and install vertical supports under the frame side members. To prevent the vehicle from rolling, place chocks under the front wheels. Remove the rear wheels.
3. Support the rear axle housing by placing a floor jack under the differential. Move the axle so that the distance between the top of the axle shaft and the damper bracket matches the ground clearance «D», given in the specifications of this chapter. The position of the bridge must remain between the distance «D» and a position corresponding to the full tilt of the vehicle until the end of the procedure.
Warning: When performing the following operation, you must wear safety glasses and protect your ears.
4. Relieve pressure in the rear suspension system. To do this, unscrew the bolts securing the air suspension compressor to the frame side member. Disconnect the air supply lines from the fittings located on the side of the compressor that faces the side member and wait until the air bleeds. Connect the pneumatic lines to the compressor, then install it on the vehicle frame and tighten the mounting bolts to the required torque.
5. Locate the raised boss on the outer edge of the air spring, which is located at the top. Its location determines the location of the protrusion that prevents rotation. Push in the tab, turn the air spring counterclockwise and disconnect it from the upper seat.
6. Press the pneumatic line into the fitting located on top of the air spring, press in the clamp and pull the line out of the fitting.
7. Disconnect from the lower seat and remove the air spring.
Installation
8. Install the air spring on the upper seat, align the mounting lugs on it with the notches in the seat.
Warning: Make sure the cushion is positioned correctly in the saddles, otherwise it may collapse while the vehicle is moving. which will result in loss of controllability.
9. The remainder of the assembly is carried out in the reverse order of removal.
10. Install the wheel and secure it with nuts. Lower the vehicle and tighten the wheel nuts to the torque specified in Chapter 1 specifications.
11. Make sure the air suspension system is working by running the engine for 1 minute.
12. Recheck ground clearance «D» (see paragraph 3).
