Withdrawal
1. Chock the rear wheels, apply the handbrake, raise the front of the vehicle and install jack stands.
2. Remove both front wheels. When removing the wheels, wrap the wheel bolts into their hubs so that the brake disc on the hub does not turn.
3. Turn away bolts of fastening and remove the lower protective casing of the engine.
4. As described in chapter 2A or 2B, transfer the weight of the motor to the hoist by attaching it to the rear lug.
5. On vehicles equipped with xenon headlights, disconnect the sensor rod from the front lower control arm as described in chapter 12.
6. Carefully remove the ABS wheel sensor.
7. As described in paragraph 6, disconnect both vertical stabilizer links from the lower arms.
8. Disconnect the inner ends of both lower arms from the subframe as described in paragraph 5. To do this, you will have to disconnect the rear corners of the subframe from the body and lower them slightly to remove the lever bolt.
9. Disconnect the lower ends of both suspension struts from the front lower arms as described in paragraph 3.
10. Disconnect the inner ends of both front lower arms from the subframe as described in paragraph 5.
11. Hang the steering knuckle, suspension strut and arms inside the arch with wire so as not to load the bushings and hinges.
12. Make sure that the power unit is securely fastened to the hoist, and dismantle the left and right gearbox supports from the subframe.
13. Turn away two bolts of fastening of a stretcher. which are located behind the brackets of the stabilizer clamps.
14. Loosen the four subframe mounting bolts located in front of the stabilizer clamp brackets until it is possible to release the subframe from the supports. Do not completely unscrew the bolts.
15. Gently lower the subframe and remove it from under the vehicle.
Repair
16. Replacing subframe bushings requires the use of a hydraulic press and a set of specially machined mandrels. Self-manufacturing of mandrels is not recommended - the supports are easily damaged. Contact your dealer for help.
Installation
Note: All nuts and bolts must be replaced.
17. Attach the subframe to the installation site and align the front supports with the appropriate brackets. Install the new front support mounting bolts, but do not tighten them at this stage.
18. Attach the gearbox supports to the subframe.
19. Attach the lower end of the suspension strut to the front lower arm as described in paragraph 3. Attach both lower arms to the subframe as described in paragraph 5. Do not fully tighten the bolts and nuts at this stage of installation.
20. Attach the vehicle level sensor link to the lower arm as described in chapter 12 (if xenon headlights are installed).
21. Pick up two pieces of wooden folder with a diameter of approximately 15 mm and a length of 150 mm. Working under the wheel arches, thread the bushings through the centering holes in the front corners of the subframe. Adjust the position of the subframe so that the sticks pass through all three holes on both sides (pic. 7.21).
Pic. 7.21. Insert a piece of wood (arrow) through three holes in the front corners of the subframe: 1. Bracket (upper); 2. Subframe; 3. Bracket (lower)
22. Install the mounting brackets in the rear corners of the subframe, insert new bracket mounting bolts and lightly tighten them. After installing the brackets, insert the new subframe mounting bolts and also lightly tighten them.
23. Disconnect the hoist and tighten the subframe and suspension mounting bolts in the order described below.
24. Tighten the four main subframe mounting bolts to the prescribed torque in two steps (pic. 7.24).
Pic. 7.24. Subframe mounting details: 1. Rear mounting bracket bolts; 2. Main fastening bolts; 3. Gearbox support bolts; 4. Gearbox support bolts; 5. Main fastening bolts; 6. Front mounting bracket bolts
25. Tighten the four front subframe mounting bolts to the prescribed torques
26. Tighten the four rear subframe mounting bolts to the prescribed torque.
27. Tighten the gearbox support mounting bolts to the prescribed torques, as described in chapter 7A or 7B.
28. Tighten the inner bolts of the front and rear lower transverse arms to the prescribed torques, as described in paragraph 5.
29. Install the vertical stabilizer links. as described paragraph 6. For fastening, use new nuts and tighten them to the prescribed torques.
30. Tighten the nuts securing the strut to the lower front arms to the prescribed torque as described in paragraph 4.
31. Reinforce the ABS wheel sensor wiring as described in paragraph 19 of chapter 9.
32. Install the bottom guard. Install wheels. Lower the vehicle and tighten the wheel bolts to the specified torque.
33. Finally, weld and align the front wheels as soon as possible.
