A) Check tire wear and tire pressure.
b) Check wheel runout.
- Wheel runout is 1.2mm or less.
V) Check front wheel bearings for looseness.
G) Check up reliability of fastening of a forward suspension bracket.
d) Check up reliability of fastening of a steering drive.
e) Check for excessive play in the ball joint.
and) Check the correct operation of the shock absorbers by performing a rebound test according to the standard method.
2. Measure the vehicle clearance.
If the height of the clearances of the car does not meet the established standards, then you should try to adjust this height by pushing the body down or lifting the body up. If the height of the gaps after this still remains incorrect, then a control check should be carried out in order to identify defective springs or other suspension parts.
3. Install the front wheel alignment hardware according to the manufacturer's instructions.
4. Adjust the angles of the front wheels.
If the camber or caster angle of the front wheel axle is out of specification, then adjustment should be made by turning the adjusting cam or turning the strut nut.
Warning: The adjusting cam should not be rotated more than 4.5 notches from its neutral position.
Warning: Do not turn the nut on the strut more than three threads from its original position.
Note: The front camber angle changes by approximately 13' per cam rotation by one notch.
Note: The caster angle changes to approximately 29'33" turning the nut one turn.
Torque:
- Adjusting cam - 216 Nm
- Strut nut - 121 Nm
If the steering axle angle is not within specifications after adjusting the camber and caster, recheck the front steering knuckle for deformation or looseness.
5. Check the toe-in of the front wheels using a special device for measuring the toe-in of the front wheels in the following sequence:
A) Make sure that the position of the front wheels of the car corresponds to the straight direction of movement, on a level surface.
b) Mark the center of the tread of each tire at the rear and measure the distance between the marks on the right and left tires.
V) Advance the vehicle so that the marks on the rear of the tires move to a height corresponding to the height of the front toe gauge mounted on the front of the tires.
G) Measure the toe-in of the front wheels, using the same points on the right and left tires.
- Nominal inspection convergence: 0±2 mm
- Rated convergence during adjustment: 0±1 mm
d) Loosen the tie rod clamp.
e) Turning the tips of the left and right steering rods by the same number of revolutions, adjust the convergence of the front wheels.
Note: after taking appropriate measurements, make sure that the length of the left and right tie rod ends is equal.
- The difference in the lengths of the tips of the left and right rods is no more than 3 mm
G) Tighten the clamp.
- Tightening torque - 25 Nm
6. Check the angle of rotation of the front wheels.
Remove the caps from the restrictive bolts of the steering knuckle and check the angles of rotation of the wheels.
Wheel angle (tolerance +0°, -3°):
Note: When turning the wheels fully, make sure that the wheels do not touch the body or flexible brake hoses.
7. If the maximum value of the angle of rotation of the steered wheels differs from the norm indicated here, then the angle of rotation of the wheels should be adjusted with the restrictive bolts of the steering knuckle.
- Tightening torque - 44 Nm
8. If the angle of rotation of the wheel still cannot be adjusted within the established norm, then it is necessary to carry out a control inspection and replace damaged or worn steering parts.
9. Check side slip
- Side slip — 3.0 mm/m no more
If side slip is greater than standard slip then check toe or other front wheel adjustments.
