I change my PSP out and it's still making this whiney noise everytime I turn the steering the wheel. I've bleed the pump several time already. Any info you can give is appreciated. TIA

 

I changed out the power steering pump but it is still making a whiney noise whenever I turn the steering wheel. I have bleed the system and made sure there is enought fluid. The only thing I can think of is when I put the vaccum switching valve back, I could have swicth the two hose somehow. Could this be making causing the noise coming from the pump. I'm lost. any info you can share is appreciated. TIA

 

On your SC400, check the screen inside the PS reseroir. Most of the time it's clogged up and won't let the fluid pass through.

 

I checked the screen. It definitely not clogged. Thanks

 

I checked the screen. It definitely not clogged. When I start up the engine and let it idle, it runs fine. It also run fine when the car is moving. It only make noise when the car is completely stop and I'm turning the wheel back and forth. I'm at a lost. Thanks

 

Do you mean the screen inside the resovoir by the radiator?

 

Where did you get your PS pump from????

 

I got the psp from AutoZone
