13.9. Angles of installation of forward wheels

An inspection of angles of installation of forward wheels needs to be carried out at the stand, at the same time the car has to be in horizontal position with the forward wheels established for the rectilinear movement. Previously be convinced that the suspension bracket and steering are in the normal state, tires and wheels have no defects.

Convergence

The convergence is defined as a difference of distances (V-and) between forward and back boards of rims of wheels. The positive convergence means that wheels are in front located more closely to each other, than behind, at measurement at height of an average point of a wheel.

If the convergence does not correspond to the required value, weaken the left and right lock-nuts of tips of steering drafts, then, rotating drafts, establish the required corners. Tighten lock-nuts. Convergence (B–A): 0±2 mm.

  • Adjustment of a convergence has to be carried out by rotation of the left and right tip of steering draft on an identical corner.
  • At adjustment of a convergence weaken an external collar of fastening of a protective cover to prevent its twisting.
  • After adjustment tighten lock-nuts of tips of steering drafts and collars of fastening of covers.
  • Adjust a convergence so that the difference between the left and right side did not differ more than on ±1 mm.

Moment of an inhaling of a lock-nut of a tip of steering draft: 50–60 N • m

Disorder

Disorder is a tilt angle of a wheel in relation to a paving in the vertical plane. It can be positive if wheels are inclined outside, or negative if wheels are inclined inside. The corner of disorder is established at production of the car and cannot be regulated. Disorder: 0 ° ± 30'.

Corner of a longitudinal inclination шкворня

The corner of a longitudinal inclination шкворня is established at production of the car and cannot be regulated. If the corner of a longitudinal inclination шкворня does not correspond to the required values, replace the bent or damaged details. Corner of a longitudinal inclination шкворня: 2 °49 '±30.


  1. Before check and adjustment of angles of installation of wheels the forward suspension bracket has to be free from the worn-out, free or damaged details.
  2. Adjustment of angles of installation of wheels needs to be carried out, using the special tool 09529-21000.
  3. Disorder and corner of a longitudinal inclination шкворня are established at production of the car and cannot be regulated.
  4. If disorder and a corner of a longitudinal inclination шкворня do not correspond to the required values, replace the bent or damaged details.
  5. The difference of a deviation of a corner of a longitudinal inclination шкворня between the left and right side of the car has to be no more than ±30'.

Adjustment of a convergence of back wheels

Convergence of back wheels: 4 (3/–1) mm.

Adjustment of a convergence of a back wheel is carried out by turn of connecting draft of the cross lever of a back suspension bracket.

Left side: rotation clockwise –> a positive convergence.
Right side: rotation clockwise –> a negative convergence.
Change of a convergence at turn of connecting draft on one turn: 0,6 mm (0,6 °).

After adjustment of a convergence tighten both nuts the required moment.

Inhaling moment: 50–60 N • m.
