Difficulty or inability to turn your car's steering wheel often points to issues within the power steering system. When you say your "car wheel stopped turning," it usually means the steering wheel is very hard or impossible to move, making it difficult to steer the road wheels.
Key Reasons for Difficulty Turning Your Steering Wheel
Modern cars use a power steering system to make turning the wheels effortless. This system uses hydraulic or electric assistance to multiply the force you apply to the steering wheel, making low-speed maneuvers, like parking, much easier. When this system malfunctions, you lose that assistance, and turning the wheel requires significant effort.
Power Steering System Problems
Problems within the power steering system are common culprits behind a steering wheel that is difficult to turn.
Stuck or Jammed Power Steering Pump
The power steering pump is a vital component that circulates hydraulic fluid under pressure. According to reference information, the power steering pump can sometimes get stuck or jammed if debris finds its way in. This prevents the pump from generating or circulating the necessary pressure, resulting in a complete loss of power steering assistance. Think of it like a blocked artery – the fluid can't flow correctly.
Power Steering Fluid Leaks
Another significant issue is the loss of power steering fluid. The power steering system could spring a leak, leading to a loss in vital power steering fluid. Leaks can occur in the hoses, pump seals, or the steering rack itself. Without sufficient fluid, the system cannot create hydraulic pressure to assist your steering, making the wheel feel extremely heavy and hard to turn.
Other Potential Causes
While power steering issues are primary suspects, other mechanical failures can also make steering difficult:
Steering Rack or Column Issues
The steering rack (or gearbox) translates the steering wheel's rotation into movement for the road wheels. Issues like internal wear, damage, or seizing can cause significant resistance. Similarly, problems in the steering column connecting the wheel to the rack can impede movement.
What To Look For (Symptoms)
If you're experiencing difficulty turning your steering wheel, look out for these signs:
- Groaning or Whining Noise: Often heard when turning the wheel, indicating low fluid or a failing pump.
- Stiff Steering: The most obvious symptom, especially at low speeds.
- Fluid Puddles: Pinkish, reddish, or amber fluid under the front of your car can indicate a power steering fluid leak.
- Steering Wheel Vibration: Sometimes accompanies pump issues.
If your steering wheel becomes difficult or impossible to turn, it's crucial to have your vehicle inspected by a qualified mechanic promptly.
