Front suspension and steering
1. Raise the front of the car and place it on stands.
2. Inspect the boots and boots for cracks or signs of wear.
3. On models with a power steering system, inspect the hoses and tubes of the system, as well as their connections for leaks.
4. Grab the wheel from above and below and try to shake it. If the free play is too great, have an assistant depress the brake pedal and shake the wheel again. If the free play has decreased or disappeared, then the hub bearings must be replaced. If there is still free play, then the connections or suspension mounts are worn out.
5. Grab the side of the wheel and try to shake it. Too much free play can be caused by worn hub bearings or tie rod ball joints.
6. Check up a condition of plugs of fastenings of elements of a suspension bracket.
7. Lower the vehicle to the ground and turn the steering wheel 1/8 turn to either side. If the steering wheel play is too great, check the steering gear joints and connections.
Suspension struts / shock absorbers
1. Inspect shock absorbers for signs of fluid leakage. If a leak is present, the shock absorber must be replaced.
2. Test the effectiveness of the shock absorbers by rocking the car up and down.
Half shafts
1. Raise the front of the car and place it on stands. Turn the steering wheel all the way to the side and slowly turn the wheel. Check the condition of the CV joint anthers by pushing the folds apart. Also check the condition and tightness of the clamps.
2. Check the condition of the hinges themselves. To do this, while holding the axle shaft, try to rotate the wheel. Then, while holding the inner joint, try to rotate the axle shaft. Excessive free play indicates wear in the joints, worn axle shaft splines, or loose axle shaft mounting nut.
3. Inspect shock absorbers for signs of fluid leakage. If a leak is present, the shock absorber must be replaced.
Instruments and electrical equipment
1. Check the operation of all appliances and electrical equipment.
2. Check the accuracy of the sensors. Turn on all the elements of electrical equipment in turn to check their operation.
Steering and suspension
Check the operation of the steering and suspension. Check that there is no vibration or noise when driving.
Transmission
Check the operation of the engine, clutch, gearbox and axle shafts. Check that they do not make any unusual noise when moving.
Brake system
1. Check that the car does not pull to the side when braking, and that the wheels do not lock up too early.
2. Check that the steering wheel does not shake when braking.
3. Check the operation of the hand brake and brake booster. To do this, depress the brake pedal several times and start the engine. The pedal should go down a little. Let the engine run for a few minutes and shut it down. Press the brake pedal. You should hear the vacuum booster hiss. After a few clicks, it should stop, and the pedal should become much stiffer.
