Description
Attention:
- The camber, longitudinal and transverse inclination angles of the turning axis cannot be adjusted.
- If the camber, pitch and roll angles of the steering axis are different from the norm, check the front suspension components. Replace damaged or worn parts as necessary.
- The lateral inclination angle of the rotation axis is a reference value and is not required to be checked.
Measure the alignment angles of the front wheels when unloaded.
Note. The unloaded state implies a full charge of fuel, coolant and engine oil. Spare tire, jack, tools and floor mats are in their original places.
Pre-check
Check the following:
- Is the tire pressure normal and is there any wear?
- runout of road wheels;
- axial play in wheel bearings; see above;
- axial play in the ball joint of the transverse arm; see above;
- rack operation;
- is there any play or deformation in the places where the axle and suspension are attached;
- are there any cracks, deformations and other damage on the suspension beam and wishbone;
- height of the unloaded vehicle.
Checking camber angles, longitudinal and lateral inclination angles of the wheel rotation axis
- The camber angles of the longitudinal and transverse inclination of the turning axis cannot be adjusted.
- Before checking, roll the car's front wheels onto a gauge to measure the steering angle. Place a stand of the same height under the rear wheels so that the car is in a horizontal position.
Check using a caliper to measure camber, pitch and roll angles of the steering axis (CCK)
Attach the SSK caliber (special tool: KV991040S0) on the wheel as follows and take measurements:
1. Unscrew the three wheel nuts and screw the guide bolts onto the hub studs.
2. Screw the adapter into the plate until it is pressed tightly against it.
3. Screw the center plate into the plate.
4. Insert the plate assembly onto the guide bolt. Install the spring then tighten the nuts evenly on the three guide bolts. When tightening the nuts, do not compress the spring completely.
5. Place the concave part of the gauge for measuring wheel alignment angles against the convex part of the central plate, press firmly and take the measurement.
Camber, pitch and roll angles of the turning axis: See paragraph below. «Technical data and specifications».
Attention:
- If the camber, pitch and roll angles of the steering axis are different from the norm, check the front suspension components. Replace damaged or worn blades as necessary.
- The lateral inclination angle of the rotation axis is a reference value and is not required to be checked.
Checking wheel alignment
Measure wheel toe as follows:
Attention:
- Always take measurements on level ground.
- Before rolling your vehicle, make sure that no one is in front of it.
1. Rock the front of the car to stabilize the suspension.
2. Roll the vehicle straight forward approximately 5 m.
3. Apply a mark (A) at the base line of the tread (behind) both wheels at the height of the center of the hub. These marks will be the measurement points.
4. Measure the distance «A» (from the back).
5. Slowly roll the car forward so that the wheels rotate 180° (1/2 turn).
Note. If the wheels have turned more than 180° (1/2 turn) take the measurement first. Do not roll the car backwards.
6. Measure the distance «IN» (from the front).
General toe A - B. General toe: See paragraph below. «Technical data and specifications».
If the toe-in differs from the norm, make adjustments by changing the length of the outer and inner tie rods.
