* Power Steering Pump: A failing power steering pump is a common cause. If it's struggling, you'll notice stiffer steering, especially under load (like turning). Low power steering fluid levels will exacerbate this. Check the fluid level; if it's low, you need to find and fix the leak *before* adding more fluid.
* Power Steering Fluid: As mentioned above, low fluid level will cause stiff steering. But also consider *contaminated* fluid. Old, dark, or milky fluid indicates problems that need addressing.
* Power Steering Rack and Pinion: Wear and tear, or damage to the rack and pinion (the mechanism that converts steering wheel rotation into wheel movement), can cause stiffness, especially if the problem is worse on one side. This is a more serious and expensive repair.
* Power Steering Hoses: Cracks or leaks in the power steering hoses will reduce fluid pressure, leading to stiff steering. Inspect the hoses carefully for any signs of damage.
* Tie Rod Ends/Ball Joints: While these affect steering, stiffening specifically on *one* side and *only* when turning right usually points to a more direct power steering problem. However, *worn* tie rod ends or ball joints could contribute to increased effort in turning, particularly if already weakened power steering is present. A mechanic would need to inspect for play in these components.
* Steering Box: Less common, but possible, is a problem within the steering box itself. This requires professional diagnosis.
* Belt Tensioner/Serpentine Belt: If the power steering pump is belt-driven (most are), a worn belt or tensioner pulley could cause the pump to not receive enough power to work properly.
Troubleshooting Steps:
1. Check the power steering fluid level: This is the easiest and first step.
2. Inspect the power steering fluid: Is it clean and the correct color?
3. Inspect the power steering hoses: Look for cracks, leaks, or bulges.
4. Listen for unusual noises: Grinding, whining, or squealing from the power steering system while turning can pinpoint a failing component.
Important: If you're not comfortable working on your car's power steering system, take it to a qualified mechanic for diagnosis and repair. Ignoring power steering problems can lead to more significant damage and potentially dangerous driving conditions. Do *not* drive the vehicle extensively with severely stiff steering.
