Forward suspension bracket Forward suspension bracket assembled
1–support of an amortization rack
2–amortization rack
3–case of bearings of wheels
4–hinge of a power shaft of a wheel
5–tightening bolt
6–cross-section lever | 7–unit beam
8–power shafts
9–stabilizer of cross-section stability
10-connecting draft plastic
11-steering mechanism
12-steering draft | Elements of a forward suspension bracket
1–a nut with a fillet, 60 N • m
Surely replace
2–cup
3–body
4–amortization rack
5–case of the wheel bearing
6–six-sided nut
7–spherical support. Situation mark. At replacement of the lever of a suspension bracket establish on the middle of an oval opening and check a track (work HUNDRED).
8–nut, 45 N • m
Being self-stopped, it is necessary to replace surely.
9–bolts, 20 N • m + 90 ° (1/4 turns)
Being self-stopped, are surely replaced.
10-a plate with a nut
11-cross-section lever
12-drive shaft
13-the combined bolt, 70 N • m + 90 ° (1/4 turns). Being self-stopped, are surely replaced.
14-bolt, 100 N • m + 90 ° (1/4 turns). The carving in a body can be repaired by means of a carving insert of Heli-Coil. The length of a carving of a repair insert should be equal to length of a carving in a body.
15-steering draft
15-connecting bar. It is made of plastic. | 17-bolt, 45 N • m
18-the combined bolt, 100 N • m + 90 ° (1/4 turns). Being self-stopped, it is necessary to replace surely. The separator nut cannot be processed. In the presence of damages on a nut it is necessary to replace a support in a set.
19-nut, 30 N • m. Being self-stopped, it is necessary to replace surely.
20-stabilizer. For removal and installation it is necessary to lower a unit beam.
21-bolt, 70 N • m + 90 ° (1/4 turns)
22-unit beam
23-nut. Being self-stopped, it is necessary to replace surely.
24-rezinometallichesky support
25-bolts cylindrical, 40 N • m.
М8 x 47.
26-lining
27-a shaft with the hinge of equal angular speeds
28-bolts cylindrical, 40 N • m.
М8 x 18.
29-stabilizer collar
30-bolt, 25 N • m
31-Tripode hinge

Forward suspension bracket – independent. Amortization racks of a suspension bracket includes a screw spring and the shock-absorber. Both amortization racks are connected by boltovy connections with a body and cases of wheel bearings. Cases of wheel bearings cope via the triangular levers connected with a beam of the unit. The beam of the unit is connected by boltovy connections with the car bottom.
Torque transfer from the engine on wheels is carried out through two power shafts which are connected by means of two hinges of equal angular speeds with wheels and the main transfer.
The correct installation of wheels is necessary for achievement of optimum road qualities and the minimum wear of tires. At excessive wear of tires, and also bad stability on the road should address on HUNDRED where optical control of installation of wheels can be made. Measurement of a running gear without application of the corresponding optical methods is impossible.
ATTENTION Performance of welding and leveling works on bearing and directing car wheels elements of a design is not allowed. Being self-stopped nuts and the bolts/nuts having corrosion, in case of repair are replaced with the new.
