* Type of Noise: Is it a grinding noise, clicking, popping, creaking, whining, groaning, or something else? Be as descriptive as possible.
* When it Occurs: Does it happen only when turning the wheel sharply? Does it occur at low speeds or high speeds? Does it happen only when turning in one direction? Does it happen when the vehicle is stationary or only when moving?
* Conditions: Does the noise change with temperature (worse when cold/hot)? Does it get louder or softer depending on how much you turn the wheel?
* Other Symptoms: Are there any other problems, such as difficulty steering, pulling to one side, or vibrations?
Possible causes, depending on the type of noise:
* Power Steering Pump: A whining noise, especially when turning at low speeds, often indicates a failing power steering pump. Low power steering fluid can also contribute to this.
* Power Steering Fluid Leaks: Leaks can lead to low fluid levels and noises from the pump. Check the power steering fluid reservoir.
* Power Steering Rack and Pinion: Grinding or knocking noises might suggest issues with the rack and pinion, which converts rotational steering wheel movement into linear motion for the wheels. Worn components or low fluid can cause this.
* Tie Rod Ends: Clicking or popping noises, especially when turning, often point to worn tie rod ends.
* Sway Bar Links: Similar to tie rod ends, worn sway bar links can produce clicking or knocking sounds.
* Ball Joints: Knocking or clunking noises, usually more pronounced when hitting bumps while turning, could indicate worn ball joints.
* CV Joints (Constant Velocity Joints): Clicking or popping noises, particularly when turning at low speeds, may come from worn CV joints in the axles.
What you should do:
1. Check the power steering fluid level: This is the easiest thing to check. The reservoir is usually located near the engine and is clearly marked. If it's low, add fluid (the correct type for your Windstar), but don't overfill. A low level could indicate a leak.
2. Listen carefully: Try to pinpoint the location of the noise. This can help you narrow down the potential problem.
3. Inspect visually: Look for leaks around the power steering pump, hoses, and rack and pinion.
4. Have a professional inspect it: If you can't identify the source of the noise, take your Windstar to a qualified mechanic for diagnosis and repair. Ignoring steering noises can lead to more serious and expensive problems.
Providing more details about the noise will allow for a more accurate assessment.
