1. Low Power Steering Fluid:
* Cause: The power steering system uses fluid to transfer hydraulic pressure, and low fluid levels can lead to air bubbles forming, causing squeaking or whining noises.
* Solution: Check the power steering fluid level and add fluid if necessary. Make sure to use the correct type of fluid for your car (refer to your owner's manual).
2. Worn Power Steering Pump:
* Cause: The power steering pump is responsible for generating the pressure needed to assist steering. Over time, the pump can wear out, leading to noisy operation.
* Solution: If the fluid level is adequate and the noise persists, the power steering pump may need to be replaced.
3. Leaking Power Steering Hoses:
* Cause: Hoses connecting the pump to the steering rack can leak, resulting in low fluid levels and air bubbles.
* Solution: Inspect the hoses for leaks and replace them if necessary.
4. Worn Steering Rack:
* Cause: The steering rack converts the hydraulic pressure into steering wheel movement. Wear and tear can cause components within the rack to become noisy.
* Solution: If the problem is within the steering rack, it may need to be rebuilt or replaced.
5. Belt Issues:
* Cause: The power steering pump is driven by a belt. If the belt is loose, worn, or slipping, it can create a squeaking noise.
* Solution: Check the condition of the belt and tighten it if necessary. Replace the belt if it's cracked or worn.
6. Dirty Fluid:
* Cause: Over time, power steering fluid can become contaminated with debris and lose its effectiveness. This can lead to increased friction and noise.
* Solution: Flushing the power steering system and replacing the fluid can help reduce noise.
Before attempting any repairs, it's always a good idea to consult your owner's manual and consider taking your Cavalier to a qualified mechanic for diagnosis and repair.
