Vehicle deviation from straight-line motion (on a straight section of road without a slope)
1. Different tire pressure on the front wheels. Check and adjust the tire pressure to the correct level (see "Checking tire pressure").
2. Different degrees of wear on the front tires. Check the condition of the tires (see "Checking the technical condition of disks, tires and hubs"). Replace worn tires. If necessary, rearrange the wheels so that the tires on one axle have the same degree of wear.
3. Different stiffness or breakage of the front suspension springs. Check the technical condition of the front suspension (see "Checking the technical condition of the front suspension") and fix the problem.
4. Different stiffness or breakage of one of the rear suspension springs. Check the technical condition of the rear suspension (see "Checking the technical condition of the rear suspension"), replace the springs as a set.
5. Wheel alignment is out of adjustment. Have your wheel alignment checked and adjusted at a specialist workshop.
6. Braking of one of the car's wheels. Check the technical condition of the brake system (see "Brake system - checking technical condition"). Replace faulty parts.
Vehicle drifts away from straight-line motion when braking
1. Different tire pressure on the front wheels. Check the tire pressure (see "Checking tire pressure"), if necessary, bring the pressure back to normal.
2. Puncture or malfunction of the valve stem of one of the front wheels. Replace the valve or replace the wheel. Check and adjust the tire pressure to the correct level (see "Checking tire pressure"),
3. One of the brake mechanisms is faulty. Check the technical condition of the brake system (see "Brake system - checking technical condition"). Replace faulty parts.
4. The hose or line of one of the brake mechanisms is pinched. Check the technical condition of the brake system (see "Brake system - checking technical condition"). Replace faulty parts.
5. Different degrees of wear of the brake mechanism parts of one of the vehicle axles. Check the technical condition of the brake system (see "Brake system - checking technical condition"). Replace unevenly worn brake discs and brake pads.
6. The anti-lock braking system (ABS) is faulty. Determine the system condition by reading the ABS fault codes using special diagnostic equipment (see "Engine management system"). Eliminate the detected malfunction.
7. The vehicle is overloaded or loaded unevenly. When transporting cargo, do not exceed the permissible axle load of the vehicle, as indicated on the identification plate (see "Identification numbers of vehicles and units"), Distribute the load evenly.
Deterioration of vehicle controllability
1. The steering rod joints are worn out. Check the technical condition of the steering (see "Steering - checking technical condition"). Replace faulty and worn parts.
2. The steering shaft joints are worn out. Check the technical condition of the steering (see "Steering - checking technical condition"). Replace faulty and worn parts.
3. The front wheel hub bearings are worn out. Check the technical condition of the wheel hubs (see "Checking the technical condition of disks, tires and hubs"). Replace faulty parts.
4. Play in the steering mechanism. Check the technical condition of the steering (see "Steering - checking technical condition"). Replace faulty and worn parts.

5. The front suspension shock absorbers are faulty. Check the condition of the front suspension (see "Checking the technical condition of the front suspension").
6. The rear suspension shock absorbers are faulty (see "Checking the technical condition of the rear suspension"). Check the condition of the rear suspension. Replace faulty shock absorbers as a set (see "Rear shock absorbers - replacement"),
