Description
Measure the front wheel alignment in the unloaded condition, which means full fuel, coolant, and engine oil. However, the spare wheel, jack and tools should be removed.
Preliminary check
1. Check if the tire pressure is normal and there is no wear.
2. Check the runout of the road wheels.
3. Check the end play in the wheel bearings.
4. Check the end play in the lower ball joint.
5. Check rack operation.
6. Check whether the axle and suspension mounting elements are tightly tightened and not deformed.
7. Check up, whether there are no cracks, deformations and other damages on drafts and levers.
8. Check the height of the unladen vehicle.
Checking the camber angles, the angles of longitudinal and transverse inclination of the axis of rotation of the wheels.
The collapse, the angles of the longitudinal and transverse inclination of the axis of rotation are not subject to adjustment.
Before checking, roll the car with the front wheels on a gauge to measure the angle of rotation. Place a stand of the same height under the rear wheels so that the vehicle is in a horizontal position.
1. Measure the camber, caster, and caster angles of the left and right wheels with a suitable gauge.
Camber: -0°48' to 0°42'
Pitch Angle: 3°45' to 5°15'
Pivot roll angle: 9°00' to 10°30'
2. If the camber, caster and roll angles are abnormal, check the front suspension components. Replace damaged or worn parts as necessary.
Wheel alignment check
Measure wheel alignment as follows:
Attention:
- Always measure on a level surface.
- Before rolling the vehicle, make sure there is no one in front of it.
1. Rock the front of the car to stabilize the suspension.
2. Roll the vehicle straight forward about 5 m.
3. Mark at the baseline of the tread (behind) both wheels at the height of the center of the hub. These labels will be the measurement points.
4. Slowly roll the vehicle forward so that the wheels turn 180° (1/2 turn).
If the wheels have turned more than 180° (1/2 turn), perform the above procedure again from the beginning. Do not roll the vehicle backwards.
5. Measure the distance «IN» (from the front).
General convergence: 2-0 mm
Checking the angle of rotation
1. Set the front wheels to straight ahead. Roll the car with the front wheels on a gauge to measure the steering angle.
2. Fully turn the steering wheel to the right and left and measure the angle of rotation.
