2000 Ford Windstar Power Steering Noise
Is the fluid low?, is the fluid dirty? Fords can have a whiny sound to them that is not abnormal to develop. The reservior surrounds the pump, so if the pump leaks, it leaks back into the system.
Low fluid will cause cavitation and cause damage.
I have had some luck with additive made by lucas products that has helped. You may want to put an inline filer into the system (and change the fluid if the fluid is dirty) as well, they are cheap.
Tie rod end Squeak can be remedied by pircing the boots of the tie rod ends and lubricating. This isn't a permanent fix but can extend the life considerably.
Suggested Repair
Check power steering fluid level and condition. Low or dirty fluid can cavitate and damage the pump; change the fluid if dirty, add an inline filter, and try a Lucas additive. Dry tie-rod ends can also squeak—lubricating the boots may quiet them temporarily but is not a permanent fix. Consider a replacement pump if the noise continues.
Conversation Summary
The owner of a 2000 Ford Windstar reports constant front-end squealing and a whine that gets louder when turning, even while parked, and suspects the power steering pump. The expert advises checking fluid level and cleanliness, noting that low fluid can cause cavitation and damage, and suggests a Lucas additive, an inline filter, and a fluid change if the fluid is dirty. A reply also mentions dry tie-rod ends; the expert says piercing and greasing the boots can quiet them temporarily.
