Front and rear upper arms
Note: Late model vehicles with sport or heavy-duty suspensions have a buffer above the rear wishbone. In addition, the upper rear arm on all production models since 1997 has a buffer stop. When replacing the rear lever, a similar lever is installed instead of the levers of the previous design.
Withdrawal
1. Chock the rear wheels, apply the handbrake and raise the front of the vehicle. Install safety supports. Remove the corresponding wheel.
2. Removing the wheel, screw its fastening bolt into the hub so that the brake disc on it does not turn.
3. On vehicles with xenon bulbs, disconnect the control rod from the front lower control arm as described in chapter 12.
4. Carefully remove the ABS wheel sensor.
5. Turn away a fastening hook, remove a collar coupling bolt from the top part of a rotary fist. Separate the upper control arm ball joints from the steering knuckle. At the same time, do not spread the gap with any screwdrivers and chisels to facilitate the removal of the support pins (pic. 5.5, a-c). Be careful not to damage the covers.
6. Remove the mounting nut and separate the rear lower arm from the base of the steering knuckle with a ball joint remover (do not damage the case). This will allow the lower bolt to be removed from the front lower wishbone.
7. Turn away a nut and take out the bottom bolt of fastening of a rack of a suspension bracket from the forward lever (see paragraph 4).
8. The upper control arm bracket bolts are located on the butt at the back of the tips - try not to damage the rubber boot (pic. 5.25).
26. Turn away a nut from a bolt from an internal kosh of the lever. To remove the bolt, you need to slightly lower the corner of the subframe. To do this, unscrew the two plate mounting bolts and unscrew the subframe mounting bolt. Note that the bolt is threaded through two holes in the subframe.
27. Slightly lower the subframe, remove the transverse arm inner bolt and remove the arm from the vehicle.
Repair
28. Thoroughly clean the lever and the area around the supports, removing all traces of dirt and anaerobic sealant. Check for cracks or other signs of damage, paying particular attention to the inner bushing and pivot. Please note that the inner sleeve is hydraulic and a leak from it indicates that the sleeve is damaged and needs to be replaced. The hinge is an integral whole with the lever and is not supplied separately for spare parts. If the lever or hinge is damaged, the entire assembly is replaced.
29. Replacing the inner bushing requires the use of a hydraulic press and this work is best entrusted to the specialists of a dealer car service or a suitably equipped garage. If such equipment is available, press the tube, relying solely on its outer edges. The sleeve is pressed in such a way that the protrusions are parallel to the central axis of the lever.
Installation
30. Installation - reverse procedure. Pay attention to the following:
- A) Use only new bolts and nuts securing the transverse arm and subframe.
- b) The final tightening of the inner bolt of the transverse arm should be carried out after the vehicle has been lowered onto the wheels.
- V) Thread the transverse arm inner bolt through the two holes in the subframe.
- G) Tighten screw connections to the prescribed torques.

32. Removing the wheel, wrap the bolt of its fastening into the hub so that the brake disc on it does not turn.
33. On vehicles with xenon headlights, disconnect the sensor actuator rod from the front lower arm as described in chapter 12.
34. Turn away a fastening nut and separate the lever from the basis of a rotary fist, having applied a puller of spherical tips (try not to damage the cover).
35. Turn away a nut and take out the bottom bolt of fastening of a rack of a suspension bracket from the lever.
36. Turn away a fastening nut and disconnect vertical draft of the stabilizer of cross-section stability from the lever, as it is described in paragraph 6.
37. Turn away a nut and take out an internal bolt of fastening of the lever. Remove the lever from the car. Pay attention to that. that the bolt is threaded through two holes in the subframe.
