Preliminary work
1. Balance the wheels and check the air pressure in the tires.
2. Check wheel bearing runout.
3. Check up an inhaling of fastenings of spherical support and rotary fists.
4. Completely empty the trunk and disembark all passengers.
5. Shake the front of the car several times to check the operation of the shock absorbers.
Note: checking and adjustment must be carried out strictly in the following sequence: longitudinal inclination of the axis of rotation → camber → convergence.
Checking the caster axis
6. Measure the pitch value of the axis of rotation using special equipment. Rated value: 4°00'±30' (to the road surface); 4°30' (to the body). If the measured value is out of the specified range, check the front suspension parts and replace the damaged element if necessary.
Attention: the value of the longitudinal inclination of the axis of rotation is determined by the design of the vehicle and cannot be adjusted. Violation of this angle indicates a malfunction of the suspension or body elements.
Camber check and adjustment
Attention: The front suspension is designed so that no camber adjustment is required.
7. Measure the camber angle (A) using special equipment. Rated value: 0°± 30' (front wheel); -1 ± 30' (rear wheel).
A. Positive camber
B. Vertical line
C. Rack Centerline
Checking and adjusting the convergence
8. Using a ruler, measure the total convergence of the front wheels (B-A). Rated value: -2-2mm (front axle); 2-6mm (rear axle). If the measured value is outside the specified value range, adjust the wheel alignment.
9. Set the front wheels in a straight position and fix the steering wheel.
10. Loosen locknut (A) tip and collar boot tie rod. By turning the tie rod, adjust the wheel alignment.
11. After completing the adjustment, tighten the boot collar and tighten the locknut. Tightening torque: 50-55 Nm.
