The bushings must be replaced in pairs - front left and right, or rear left and right. (and not one by one or diagonally).
Dismantling
1. Place the vehicle on a lift.
2. Raise the rear of the vehicle.
CAUTION: Do not work under a vehicle supported solely by a jack or lift. Always support the vehicle with safety stands.
3. Remove the rear wheels.
4. Release air from the air suspension system.
REAR SUSPENSION, ADJUSTMENTS, Air suspension - releasing air and filling the system with air.
5. Remove the rear propeller shaft.
DRIVE SHAFTS, REPAIR WORK, Cardan shaft - rear.
6. Disconnect the rear height sensor multi-pin electrical connectors.
7. Remove the Allen screws that secure the brake hose clamps to the upper control arms.
8. Loosen the clamps securing the wheel speed sensor and brake pad wear sensor wiring to the upper suspension arms and body.
9. Loosen the clamps securing the air suspension system hoses to the body.
10. Place a jack as a support under the lower suspension arm.
CAUTION: Do not leave the lower control arm suspended by the air spring.
11. Unscrew the bolts securing the shock absorbers to the lower arms.
12. Remove the fuel coolant heater and fuel pump from the rubber mounts.
13. Place a jack as a support under the rear subframe.

14. Remove the 2 subframe mounting bolts, which are diagonally located on opposite sides. Remove the disc washer and the exhaust pipe mounting bracket. Place the disc washer and the exhaust pipe mounting bracket on the support bolts. Use the support bolts as supports for the subframe.
15. Screw the bolts onto the subframe by hand. Screw the bolts in to a depth of at least 16 mm.
16. Unscrew the 2 remaining subframe mounting bolts.
17. Lower the subframe to provide access to the bushings.
18. Remove the rings with slots from the supports.
19. Mark the location of the bushing on the subframe. To do this, apply a mark on the subframe with paint.
20. Assemble the LRT-51-024/7 device.
21. Install the LRT-51-024/8 puller on the bushing and the LRT-51-024/7 tool on the subframe. Screw the LRT-51-024/11 screw into the LRT-51-024/8 tool, align the tool and remove the bushing.
Assembly
1. Clean the bushing and its seating surface from dirt.
2. Apply rubber lubricant to the new bushing and its mounting hole.
3. Install the LRT-51-024/10 device, which is designed for mounting bushings, onto the subframe.
4. Place the LRT-51-024/9 tool onto the LRT-51-024/11 stud and place the new bushing on top.
5. Screw the LRT-51-024/11 stud into the LRT-51-024/10 tool.
6. Rotate the bushing so that its alignment mark aligns with the paint mark on the subframe.
7. Install the sleeve and remove the tool.
8. Repeat the procedure for the sleeve located diagonally on the opposite side of the subframe.
9. Raise the subframe to the body and unscrew the support bolts. Insert the bolts through the bushings located on opposite sides and screw them in by hand.
10. Lower the subframe.
11. Remove and replace the remaining bushings.
12. Install the two slotted rings onto the corresponding bushings. Raise the body subframe so that a small gap remains to install the remaining rings.
13. Install the disc washer and exhaust pipe bracket, tighten the two bolts, but do not tighten them completely yet.
14. Remove the support bolts from the subframe and remove the disc washer and exhaust pipe bracket.
15. Secure the disc washer and exhaust pipe bracket with the remaining subframe mounting bolts. Install the rings on the bushings and tighten the bolts to the subframe.
16. Install the subframe onto the pins.
17. Tighten the subframe mounting bolts to 165 N·m (122 lb ft). Before tightening the bolts, make sure the slotted rings are correctly positioned relative to the bushings.
18. Install the fuel pump on the supports.
19. Tighten the shock absorber mounting bolts to the lower arms. Do not tighten the bolts completely yet.
20. Secure the air suspension system hoses to the body.
CAUTION: Make sure that the location of the hose alignment marks matches the location of the clamps.
21. Secure the wiring for the wheel speed sensors and brake pad wear sensors.
22. Install the brake hoses in place and secure their clamps.
23. Connect the multi-pin connectors of the body height sensors.
24. Install the rear propeller shaft.
DRIVE SHAFTS, REPAIR WORK, Cardan shaft - rear.
25. Bring the pressure in the air suspension system to the nominal value.
26. Reinstall the rear wheels and tighten the nuts to 140 N·m (103 lb ft).
27. Tighten the shock absorber-to-lower arm bolts to 110 N·m (81 lb ft).
