Power steering
| malfunction | Its reason | Troubleshooting |
| A. Steering noise. | 1. ATF level too low. 2. The V-belt tension is too low. 3. The V-belt is worn or damaged. | Fill the tank according to the instructions. Find the location of the leak. Tighten the V-belt. Check if the tension roller moves easily, replace if necessary. Install a new belt. Replace. |
| B. The servo drive is out of order. | 1. See A. 1 and 2. 2. The hoses are clogged. 3. Too low pressure in the system. 4. Air in the system. | Clean the hoses or replace them. Check the pressure in the system. Remove air and find the reason for its entry into the system. |
| C. As the turning angle increases, the steering wheel becomes heavier. | 1. See B. 3. 2. The steering valve is faulty or clogged. | Replace the pump. |
| D. The steering wheel turns on its own constantly in one direction or another. | 1. Large difference in tire pressure. 2. The geometry of the wheels is damaged or deformed. 3. Hydraulic lines are damaged or there is insufficient ATF. | Check your tire pressure and pay attention to uneven tire wear. Check steering and suspension, adjust steering and replace faulty parts. Replace the pipes. |
| E.The steering wheel does not return to the straight position well or does not return at all. | 1. The steering shaft or suspension joints have a hard movement. 2. The fluid drain hose or wire is narrowed or kinked. 3. The toothed rack has a heavy stroke, which may be due to damage to the toothed rack piston or sealing rings. | Replace worn or damaged parts. Install new parts. Check and replace if necessary. |
| F. Servo drive leakage. | 1. ATF leaking through hose or pipe connections. 2. Defective rack seals. | Tighten the connections or install new O-rings. Remove the steering gear, disassemble it and install new seals. |
Note. Recommendation: if noises appear in the power steering gear, remember that the operation of the power steering pump is accompanied by noises. These noises can be heard when the car is stationary with the engine running, especially when the steering wheel is fully turned. When the speed increases, the noises may increase. To diagnose the malfunction, it is necessary to localize the noises of nearby units, due to which the noises can be confused (for example, the noise of the V-belt tension roller).
