Wheels and tires

Verification procedures

Perform diagnostics on the state of the tire (Fig. 4.1).

The corners of the front axle

When checking the alignment of the front wheels by means of a special device (wheel alignment tester) always set the vehicle on a flat surface so that the front wheels were in the straight-ahead position. Before testing, make sure that the front suspension, steering and wheel are in good technical condition. Also, check that the wheels are in the straight-ahead position, and the tire pressure is correct.

Toe (toe-in)

Toe (the difference in the size of A or the angles a + b) is adjusted by rotating the tips of steering drafts. To change the toe tips rotate the right and left steering rod at equal angles in opposite directions. The amount of convergence will be reduced by the rotation of the tip left tie rod toward the rear of the vehicle (and the steering rod tip right - toward the front of the car).

Toe-B-A

Standard value: 0 ?� 2 mm.

Adjusting the slip angles and steering wheel (side slip and steering angle)

Slipping is adjusted by turning the side tie rod.

The rotation angles of the wheels are governed by the nominal torque, turning right and left side tie rods in opposite directions to specific angles.

External wheel turning angle: 32 ?� 73 '?� 2.

Internal rotation angle of the wheels (the difference between the left and right should be no more than 2 ?�): 37 ?� 41 '?� 2.

The difference of the interior angles of rotation of the wheels of the means of torsion: 0,65 ?�.

Tightening torque lock nut steering rod side: 50-55 Nm.

Camber (camber)

The collapse of the front wheels is provided by the geometry of the front suspension (relative position knuckle and strut front suspension) ie adjusted at the factory and can not be adjusted during operation.

Camber 0 ?� ?� 30 '.

Longitudinal slope of the axis of rotation (caster)

Longitudinal slope of the axis of rotation is adjusted at the factory and can not be adjusted during operation. If the pitch axis of rotation is not the standard value, replace the deformed or damaged suspension components.

Longitudinal slope of the axis of rotation 2 ?� 30 '?� 30'.

For wheel alignment used a special tool (09529-21000) (Fig. 4.5).

The longitudinal inclination of the axis of rotation and camber are adjusted at the factory and can not be adjusted during operation.

If the pitch axis of rotation and camber is not within the standard value, replace the deformed or damaged suspension components.

The corners of the rear axle

Toe (toe-in): 0 ?� 2 mm.

The tip of the left arm: clockwise rotation increases the toe.

The tip of the right arm: clockwise rotation reduces toe.

When adjusting the convergence of the cam bolt (cam bolt) to be turned left or right, not more than 90 ?� from the central position.

Camber

Adjusting the upper arm rear suspension held cam bolt (Fig. 4.7).

Install the left and right of the spring according to the color markings.

When adjusting the convergence of the cam bolt (cam bolt) to be turned left or right, not more than 90 ?� from the central position.

Camber (camber): 0 ?� 30 '?� 30'.

Check tire wear

Measure the tire tread depth.

Tread depth (minimum allowable value): 1.6 mm

If the height of the tread is less than the minimum value, replace the tire (Fig. 4.8).

Check runout

The wheel is one of the axes of the car and set under the safety car rack.

Measure the runout with a dial indicator as shown in Figure 4.9.

Replace the tire if its runout exceeds the limit.

Runout (maximum permissible value, steel disc):

- Radial - 0.6 mm;

- Axial - 1.0 mm.

Alloy wheels:

- Radial - 0.3 mm;

- Axial - 0.3 mm.

Tightening the wheel nuts

Tightening torque of the wheel nuts: 90-110 Nm.

Tighten all the wheel nuts in the sequence shown in Figure 4.11.
