Elements of a suspension bracket of forward wheels

1 — the Bolt, 75 Nanometers 2 — the Washer 3 — the Bolt. Surely replace 4 — the suspension bracket Lever top back. Replace a support 5 — the Bolt, 7 Nanometers 6 — the Bolt 7 — the Self-stopped nut, 50 Nanometers, surely replace 8 — the Bolt 9 — the Self-stopped nut, 40 Nanometers, surely replace 10 — the suspension bracket Lever top forward. Can act only together with a support 11 — Amortizatsionaya is resistant 12 — the Bolt. Surely replace 13 — the Directing lever with a hydrosupport. If on a hydrosupport considerable leak of oil appears, the support needs to be replaced 14 — the Nut, 120 Nanometers which is self-stopped. Surely replace 15 — the wheel bearing Case 16 — the Bolt with a fillet, surely replace. Inhaling moment: M14 bolt: 115 And then tighten Nanometer on 180 °; M16 bolt: 190 And then tighten Nanometer on 180 °; 17 — the Bolt, 10 Nanometers 18 — the Cover 19 — the Nut, 90 Nanometers which is self-stopped. Surely replace 20 — the Bolt

21 — the Support of a beam of the power unit 22 — the Bolt, 55 Nanometers 23 — the Bolt, 110 Nanometers and then tighten on 90 °. Surely replace 24 — the Bolt, 40 Nanometers and then tighten on 90 °. Surely replace 25 — the Rod 26 — the Bolt, 40 Nanometers and then tighten on 90 °. Surely replace 27 — the Bearing lever lower 28 — the Bolt. Surely replace 29 — the Bolt, 75 Nanometers. Surely replace 30 — the Beam of the power unit. Attention: Do not lift the car for a beam of the power unit 31 — the Nut, and then tighten 70 Nanometers on 180 °. Surely replace 32 — the Nut, and then tighten 70 Nanometers on 180 °. Surely replace 33 — the Screw with an internal polyhedron. Previously tighten the moment 15 Nanometers, then the next moment: M8 screw = 40 Nanometers M10 screw = 70 Nanometers 34 — Podkladnaya a plate 35 — the Power shaft 36 — the Bolt. Surely replace 37 — the Nut, and then tighten 50 Nanometers on 90 °. Surely replace 38 — the Nut with a fillet, 50 Nanometers. Surely replace

The four-lever, independent suspension bracket of forward wheels has depreciation racks of McPherson and the torsion stabilizer of cross stability.

Depreciation racks consist of cylindrical screw springs, shock-absorbers in the form of a double pipe and the top support of the big size. The stabilizer does not participate in the direction of wheels, and through connecting bars is connected with depreciation racks.

The depreciation rack is fixed by bolts to a support of the top lever and to the forward cross lever.

Optimum running characteristics and the minimum wear of tires it is reached only in that case when wheels hold the correct position. At the wrong wear of tires, and also at insufficient stability on the road it is necessary to perform optical measurements and, if necessary, to adjust the angles of installation of wheels.

Torque transmission of the power unit on wheels is carried out through two power shafts, each of which, via two hinges of equal angular speeds, is connected with wheels and the main transfer.
