If your car's steering has gone hard, there are several possible reasons:
1. Power Steering Fluid Issues:
* Low Fluid Level: Check the power steering fluid reservoir. If it's low, add the correct type of fluid.
* Contaminated Fluid: Dirty or old fluid can cause problems. Consider flushing and refilling the system.
* Leak: Inspect the hoses and seals for leaks.
2. Mechanical Issues:
* Power Steering Pump Failure: The pump is what creates the hydraulic pressure that assists steering. A faulty pump can cause hard steering.
* Steering Rack Problems: This is the mechanism that converts steering wheel movement to wheel movement. Wear or damage can cause stiffness.
* Steering Column Issues: Problems in the steering column itself can also affect steering feel.
3. Other Possibilities:
* Tire Pressure: Uneven tire pressure can make steering feel heavier.
* Alignment Issues: A misaligned car can cause steering to feel tight or pull to one side.
Important Note: It's best to have a qualified mechanic diagnose the problem.
What to do next:
1. Check the power steering fluid level. If it's low, add the correct type of fluid.
2. If the problem persists, take your car to a mechanic. They can diagnose the issue and recommend the appropriate repair.
