Removal

 PERFORMANCE ORDER

  1. Hang out the car above the ground.
  2. Remove forward wheels.
  3. Release a nut of fastening of a bar of the stabilizer of cross resistance to the corresponding lower lever of a suspension bracket (see the Section Removal, check of a condition of components and installation of the stabilizer of cross stability).
  1. Release a nut (1) of an axial bolt of fastening of a fork of rack-mount assembly to the lower lever of a suspension bracket.
  1. Take an axial bolt of a fork.
  1. Release coupling bolts and remove a fork (1) of the lower support of rack-mount assembly.
  1. Open a cowl and through an aperture in a mudguard of a wheel arch release three nuts of fastening of rack-mount assembly to the basic block on a frame.
  1. Take rack-mount assembly from a wheel arch.

Dismantling

Design of rack-mount assembly of a forward suspension bracket

1 — the Nut
2 — the Top holder
3 — the Top insulator
4 — the Aligning washer
5 — the Top cup of a spring
6 — the Screw spring

7 — Nizhny Novgorod the insulator
8 — Nizhny Novgorod the holder
9 — the Boot
10 — the Lower saddle of a spring
11 — the Shock-absorber
12 — the compression course Buffer


 PERFORMANCE ORDER

  1. Clamp a rack in a vice with soft sponges and on several turns release a nut of a piston rod of the shock-absorber, - do not remove a nut finally.
  1. Clamp the lower basis of rack-mount assembly in a vice with soft sponges and by means of special adaptation squeeze a screw spring.
  1. Turn off a nut of a piston rod and make dismantling of a rack.

Check

 PERFORMANCE ORDER

  1. Clamp the lower part of the shock-absorber in a vice with soft sponges and manually check smoothness and uniformity of a piston stroke of the shock-absorber in both directions.
  1. Having rocked a piston rod not less than three times, make sure of lack of signs of development of leaks.
  2. Visually estimate a condition of a screw spring.
  3. Check the top cup and the lower saddle of a spring for existence of damages, also estimate a condition of the top and lower rubber insulators.

Assembly

 PERFORMANCE ORDER

  1. Working as it should be, the return to a dismantle order, install into place components of rack-mount assembly, - track correctness of landing and - where it is required - input in gearing of all elements.
  2. Squeeze a screw spring and freely screw a nut of a piston rod.
  3. Clamp rack-mount assembly in a vice with soft sponges and tighten a nut of a piston rod with the required effort (37 ÷ 46 Nanometers).

Installation

 PERFORMANCE ORDER

  1. Installation is made as it should be, the return to an order of dismantle of components, - track observance of requirements of Specifications of the Head Podvesk and steering to efforts of tightening of carving fixture.

Final tightening of fixture of a rack is made after lowering of the car on the earth.

  1. In conclusion drive away the car in a workshop of car service for check and adjustment of angles of installation of forward wheels (see the Section Check and adjustment of angles of installation of forward wheels).
