* Power Steering Pump: This is a common cause. A failing power steering pump can create squealing, especially when the pump is under load (like when turning the wheel). Low power steering fluid is a major contributor here. Check your fluid level and condition. If it's low, top it off (with the correct fluid type – consult your owner's manual), but be aware that a low fluid level is a *symptom* of a failing pump, not necessarily the cause.
* Power Steering Belt: A worn, loose, or glazed power steering belt can squeal, especially when turning. Inspect the belt for cracks, fraying, or glazing. It should be taut; if it's loose, it needs adjustment or replacement.
* Power Steering Fluid: Old, dirty, or low power steering fluid can cause squeaking. Flush and replace the fluid if it's dark, smells burnt, or is low.
* Power Steering Rack and Pinion: The rack and pinion is the mechanism that converts the turning of the steering wheel into movement of the wheels. Worn seals or bushings within the rack and pinion can cause squeaking, especially when turning. This is a more serious and expensive repair.
* Steering Column: Worn bearings or bushings in the steering column itself can cause noise, though this is less common than power steering issues.
* Idler Pulley or Tensioner Pulley: These pulleys guide the serpentine belt (which drives the power steering pump and other accessories). Worn bearings in these pulleys can cause squealing.
Troubleshooting Steps:
1. Check Power Steering Fluid: This is the easiest and cheapest thing to check first. Top it off if low, but don't ignore it if it's consistently low.
2. Inspect the Power Steering Belt: Check for wear, cracks, and looseness. If damaged or loose, replace it.
3. Listen Carefully: Try turning the steering wheel slowly and then quickly. Note if the squeak changes in pitch or intensity – this can help pinpoint the source.
4. Professional Inspection: If you can't identify the source, take your car to a mechanic. They have the tools and expertise to diagnose the problem accurately.
A 1996 car is older, so it's possible multiple components are contributing to the squeak. Addressing the power steering system first is usually a good starting point due to its frequent involvement in this type of issue. Don't delay addressing the problem, as ignoring power steering issues can lead to more expensive damage.
