Withdrawal
Attention! The suspension strut is removed as an assembly with the support bracket of the upper arms. Before removing the rack, it is required to remove air from the air spring. The manufacturer recommends performing this operation using a diagnostic tester.
1. Mark with paint the position of the front wheel to be removed on the hub. This will allow the assembly to set the balanced wheel in its original position.
2. Remove the cap or protective cover and loosen the wheel bolts to be removed without jacking up the vehicle.
3. Remove air from the air spring.
4. Jack up the front of the car, install it on the jack stands and, having unscrewed the fastening bolts, remove the wheel.
5. Support the subframe with a garage jack by placing a block of wood so that the suspension does not sag after the suspension strut is disconnected. Failure to do so may result in damage to the lower control arm mounts.
6. Unscrew the union nut 1 of the air supply pipeline on the residual pressure valve 2 and release the pipeline from the holder on the spring strut (see illustration). Close the openings on the valve and pipeline with suitable plugs to prevent contamination from entering them.
2.6. Unscrew the union nut 1 of the air supply pipe on the valve 2 for maintaining residual pressure
Attention! Dismantling of valve 2 for maintaining residual pressure is not allowed.
7. Remove clamp 3 with pliers or pliers (see illustration 2.6). Subsequent installation of this clamp is optional.
8. Unscrew the nut 1, remove the hexagon head bolt 2, which locks the fingers of the ball bearings of the upper levers on the steering knuckle, and disconnect both levers from the steering knuckle by pushing them up (see illustration).
2.8. Unscrew the nut 1, remove the hexagon head bolt 2 and disconnect both levers from the steering knuckle by pushing them up
Attention! It is not allowed to spread the slot on the steering knuckle with a chisel or other tool. Bolts 3 and 4, with which the ball joint of the tie rod end is attached to the fist, must not be loosened or unscrewed (see illustration 2.8). Otherwise, you will need to perform camber and convergence of the wheels.
9. Unscrew a bolt and disconnect draft of the gauge 6 of a road gleam from the bottom bearing arm (see illustration).
2.9. Unscrew the bolt and disconnect the ride height sensor rod 6 from the lower carrier arm:
2 - a bolt of fastening of hoses of the stabilizer of cross stability to a rack
3 - a bolt of fastening of the bearing arm
4 - a bolt of fastening of a rack of the stabilizer of cross-section stability
5 - ABS sensor mounting bolt
10. Unscrew bolt 1 of fastening of the bottom support of an amortization rack to the bearing arm (see illustration 2.9).
11. Disconnect plug 2 (see illustration).
2.11. Disconnect plug 2
12. Unscrew bolts of fastening of a broad tank of system of cooling (see arrow in illustration), remove the tank and move it to the side without disconnecting the hoses from it. Remove fairing box.
2.12. Unscrew bolts of fastening of a broad tank of system of cooling (see arrow), remove the tank and move it to the side: 1 and 2 - clamps for attaching hoses to the nozzles on the tank
13. Remove the rubber bushing on the shock absorber support bracket and upper arms (see arrow in illustration).
2.13. Remove the rubber bushing on the suspension strut support bracket and upper arms (see arrow)
14. Unscrew, being careful, nuts 1 of fastening of the top support of an amortization rack to a basic arm (see illustration).
2.14. Unscrew, being careful, nuts 1 of fastening of the top support of an amortization rack to a basic arm
15. Remove the shock absorber by lowering it down.
Installation
16. Fix the suspension strut support bracket to the body by inserting the centering bushings into the corresponding holes.
17. Install the suspension strut lower yoke on the carrier arm, insert the bolt and screw in a new nut 1. Tighten the nut to a final torque of 90 Nm only after the vehicle has been mounted on wheels.
18. Screw in the bolts of the support bracket to the body (see illustration). The bolts are tightened in the sequence of their numbering.
2.18. The tightening of the bolts of the suspension strut support bracket is carried out in the sequence of their numbering
19. Insert the fingers 2 of the ball bearings of the upper arms into the holes on the steering knuckle 3, press them in to the stop with a suitable puller, insert the tightening bolt and screw the nut 1 onto it (see illustration).
2.19. Insert the pins 2 of the ball bearings of the upper arms into the holes on the steering knuckle 3, press them in to the stop with a suitable puller, insert the tightening bolt and screw the nut 1 onto it
Attention! Tightening the nut to the final torque should be done after the vehicle is mounted on the wheels.
Installing the remaining dismantled components is carried out in the reverse order of their removal.
Attention! After completing the work, the air suspension should be brought into working position by pumping in gas, the pressure of which should be in the range of 3.5-4.5 bar. New air struts come with minimal pressure, so they should be inflated.
