Wheels and tires

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 a normal condition, and the tire pressure is correct.

Toe

Toe (the difference in the sizes - A, or the angles a + b) is adjusted by rotating the tips of steering drafts (Fig. 4.1).

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).

Convergence in A: nominal value - 0 ?� 2 mm.

When adjusting the toe-clamps to loosen the protective covers of steering rods to prevent twisting of covers.

After adjustment, tighten the locknut tips of steering drafts and securely clamps set of protective covers.

Adjust the toe so that the result is consistent with the range of +1 mm.

Tightening torque rod end lock nut: 50-55 Nm.

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 ?� + 301.

Longitudinal slope of the axis of rotation

Longitudinal slope of the axis of rotation is adjusted at the factory and can not be adjusted during operation (Fig. 4.3).

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: 49 ?� 2 '30'.

For wheel alignment used a special tool (09529-21000) (Fig. 4.4).

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 difference in angle setting (pitch axis of rotation and camber) between left and right wheels must be in the range of 0 ?� ?� 30 '.

The corners of the rear axle

The rotation of the tip of the left arm in a clockwise direction increases the toe (Fig. 4.5).

The rotation of the tip of the right arm clockwise reduces toe (see. Fig. 4.5).

Standard value: 3-7 mm.

Tyre wear

Measure the tread depth (Fig. 4.6).

Tread depth (minimum allowable value): 1.6 mm.

If the height of the tread is less than the minimum value, replace the tire.

Measure 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 4.7.

Replace the tire if its runout exceeds the limit.

Runout (maximum permissible value of the radial runout of the steel disc): 0.6 mm.

Alloy wheels:

Axial ..... 1.0 mm

Radial ...... 0.3 mm

Axial ...... 0.3 mm

Tightening the wheel nuts

Tightening torque of the wheel nuts to the wheel with steel disc wheels with aluminum disks of the same.

Tightening torque: 90-110 Nm.

Tightening the wheel nuts (Fig. 4.9).

Check the tightening torque of the wheel nuts after tightening to the specified torque in a diagonal sequence.

Shift of wheels

When moving the wheels, use the circuit shown in Figure 4.10.

Checking Stability

If the vehicle is in motion leads to the side, then change Fitting in accordance with the following procedure.

Swap the front right and front left wheel, then run tests to dorzhnye ESP (Fig. 4.11).

If the car leads in the opposite direction, then reverse the front and rear wheels, then follow dorzhnye test (Fig. 4.12).

If the car leads to the side, then again, swap the front right and front left wheel, then follow dorzhnye test (Fig. 4.13).

If the car leads in the opposite direction, then replace with new front-wheel drive (Fig. 4.14).
