Before replacing any parts, the source of the whining needs to be isolated. You can use a car stethescope or a long screwdriver and carefully place the end on various areas at the front of the engine and listen for where the noise is the loudest. Another method is to remove the serpentine belt and rotate each pulley that is driven by the belt, listen for noise and feel for rough movement.

Try removing the belt and see if the pulley pulls out of the pump housing. I've seen the pump shafts break, especially in sub-zero temperatures

if you have not replaced the tension pulley and the idler pulley it might be them. but i too just had my power steering pump replaced and i took it back. the garage said that ford states that a manufactured pump has a 500 mile break in time. if after that then you have a bad pump and should be replaced again.

While you had the serpentine belt off, did you turn the different pulleys to see if any of them were wobbily or hard to turn? If not, that would be something that you go do to localize the sound.

Also watch the belt as it is turning! Normal operation should be a smooth rotation without wobble. If there seems to be unnatural movement in a certain area, that is an area you should concentrate on.

Sounds like the pump. Here is a way to test it. Take a pair of pliers and pinch off the return line to the pump when the engine is running. (only do this for about 5 sec.) If the pump is running, it will whine and howl when you do this. If it doesn't make any noise when you pinch the line, the pump is bad.

Whining when i press gas


normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.
