there is a winning sound comming from the laft side were the power stearing pump is and we replaced it but still making noise even louder.

 

Did you check the fluid type. I think it's supposed to use MERCON 1 ATF. You need to bleed it by turning the steering wheel to the stops in both directions until it's quiet and smooth.

 

It's not that I don't have confidence in aftermarket parts, but there are so many problems with power steering pumps, PCM s, MAF sensors and many after market parts that we get a little "gun shy" after a while. Most of the time entrapped air in the power steering system will give whining noises , but a good portion of the time the only way to get rid of the noise was to purchase an OEM pump.
