* Low Power Steering Fluid: This is the most frequent reason. Low fluid level leads to air getting into the system, causing whining, groaning, or squealing noises. Check the fluid level immediately and top it off if necessary. If the level is consistently low, you have a leak somewhere in the system that needs to be addressed.
* Worn Power Steering Pump: A failing pump often produces a whine, especially when turning the steering wheel. The whine may increase with engine speed. A failing pump will eventually fail completely, leaving you without power steering.
* Worn Power Steering Belt: A slipping or worn belt can cause squealing or chirping, particularly at startup or when turning the wheel. Inspect the belt for cracks, glazing, or wear.
* Leaks in the Power Steering Hoses or Rack and Pinion: Leaks anywhere in the system can cause low fluid levels and associated noises. Inspect all hoses and the rack and pinion for visible leaks.
* Worn Power Steering Rack and Pinion: A worn rack and pinion can cause groaning, clicking, or knocking noises, especially during turning. This is a more serious issue requiring repair or replacement.
* Internal Power Steering Components: Worn bearings or seals inside the power steering pump or rack and pinion can also cause noise. This is usually more of a subtle groan or whine, which will likely get progressively worse over time.
To Diagnose:
1. Check the power steering fluid level: This is the first and easiest step.
2. Listen carefully to the noise: Is it a whine, squeal, groan, click, or knock? When does it occur (only when turning, at startup, all the time)? This helps narrow down the possibilities.
3. Inspect the power steering belt and hoses: Look for cracks, wear, or leaks.
4. Have a qualified mechanic inspect the system: If you can't pinpoint the problem, a professional mechanic will have the tools and expertise to diagnose and repair the issue.
The Prowler's unique design might present some challenges in accessing certain power steering components, making professional diagnosis and repair even more important. Don't delay addressing the noise, as continued operation with a failing power steering system can lead to more extensive and costly damage.
