Power Steering whine

I have a Job 1 08 PSD with 21,000 mi. I've had zero problems for two years. Just yesterday, I noticed a whining noise that got louder when I turn the steering wheel. Guessing power steering problem. Anyone else experience this?

I think it's a sign of air in the system or a squeeky belt. Check both, turn the wheel lock to lock (in the dirt would be good) to try to purge air out. Watch the fluid level.

A bad pump would be a random thing and could happen to anybody.

If it does it consistatly take it to the dealer. You are still under the bumper to bumper warranty.

x2 for checking the fluid level. Plus make sure it is full before you even take it in so that is eliminated in the dealers mind.

problem solved, Thanks

When I first checked the fluid, looked ok. After posting this, I rechecked, and the fluid was really foamy. I stirred it a bit, and it then was below the min. I added Merc ATF (as per owner's manual) and the whine went away. Thanks to all who replied.

Good question. There was no apparent leaks or seepage. I am on Ford's extended service plan for severe conditions, and I've assumed they check all vital fluids. My dealership has a good reputation, and so far I've been very satisfied. Any ideas?

Do yourself and your truck a favor and always double check your fluids after they have had your truck.
