Cause | Remedy |
recoil (back thrusts) on the steering wheel | |
Loose or worn pump drive belt | Replace the belt or adjust its tension. |
The steering wheel turns with great effort | |
Loose or worn pump drive belt | Adjust belt tension. |
Low liquid level in the filling tank | Add liquid. |
Low engine idle speed | Adjust idle speed. |
Dirty fuel tank filter | Replace filter. |
Low pressure power steering pump | Repair or replace the pump. |
There is air in the hydraulic booster | Check the tightness of the seals and bleed the air. |
Turning the steering wheel in the middle position requires a lot of effort | |
Power steering pump failure | Check the pump and repair or replace it. |
Mechanical failure | Check the steering system. |
Turning the steering wheel to one side requires a lot of effort | |
Pump failure | Check pump and repair or replace seals. |
Turning the steering wheel quickly requires a lot of effort | |
Loose pump drive belt | Adjust belt tension. |
Idle speed too low | Adjust the engine. |
There is air in the hydraulic system | Locate the air leak and remove the air. |
Power steering pump failure | Repair or replace the pump. |
Mechanical failure | Check steering system mechanisms. |
Fuzzy steering | |
Low liquid level in the filling tank, liquid leak | Add fluid and stop leak. |
There is air in the hydraulic booster | Check seals for leaks and bleed air. |
Wear of steering parts. The geometry of the steering gear is broken. | Check the condition of the nodes and eliminate the detected malfunctions. |
Tire failure | Check and replace tires if necessary. |
Noise at work | |
Low liquid level in the filling tank | Add fluid, check for leaks. |
Discharge of liquid through the safety valve (whistling sound when the steering wheel is in the extreme position) | Determine cause and bleed air. Check and repair or replace the pump. Check pump operating pressure. |
Vibration | |
There is air in the hydraulic booster | Determine cause and bleed air. |
Mechanical damage or poor condition of the rubber | Identify unusable tires and replace. |
Additional checks for microprocessor steering
