I have read thru all the threads about power steering problems and tried all the tricks and it's still here.

The problem is there is a very loud whine when the car is running. The whine goes away when I took the serpentine belt off the car and started it. I replaced the power steering pump, the belt, tensioner, and the ac compressor. The noise is still there. I fluid the system with 2 quarts of power steering fluid. Refilled and bleed the system and the noise is still there. We thought maybe it's a bad pump so I took the pump off my car which I know is good and it's still there. Car steers fine. turn the wheel nice and easy.

I also took white lithium grease and sprayed all the pulleys minus the water pump and the alternator.

I took the belt off and made a belt out of zip ties (I know but it worked lol) I wriped it around the crank pulley and then all the pulleys one at a time to rule each one out and non of them made noise but as soon as I put the belt back on the noise is still there.


Anyone have any ideas?

 

You replaced the pump with what: a new one, a used one, a reman one, a junked one? Anyway, if replaced with a known good one then the only thing that remains is the rack.

BTW, don't put grease on pulleys unless you follow that by degreasing the pulleys and replacing the belt.

 

I have two possible solutions please look at the threads below:

If the belt is too tight it can cause a whine ... ask me how I know

I had a strange tension issue on the brkt.

 

it ended up being the idler pulley i took it off and then but it back on and the noise went away. thanks guys for the help!!
