Fluid level OK?   2. Open the cap on the PS reservoir while its running...foamy??? If so the system needs to be primed/bled...procedure:   -Fill reservoir to correct level -Start engine and run for 2 or 3 seconds and shut down. Check fluid level again...add if necessary. Repeat procedure till fluid level is constant -Raise the front of the vehicle until the wheels are off the ground -start the engine and give it a little gas & hold it there...turn the wheel all the way to the right and them all the way to the left (gently) Check fluid level and add if necessary. -Lower to the ground...with the engine still running, drive forward just enough to turn the wheel all the way to the right but don't force it against the stop, then drive forward again to get it all the way to the left stop but don't force it. -recheck the fluid and add if necessary   This should get the air out of the system & get rid of your noise. You may have to do it 2x...if the noise persists or if the fluid is persistently foamy, you might have a leak somewhere letting air in...good luck Replies to this message: cyberx1 (Mar 21, 2008 10:12 pm) cyberx1 (Mar 22, 2008 12:12 pm) 442dude (Mar 22, 2008 1:32 pm)

Replying to: 442dude (Mar 21, 2008 2:31 pm) Oh, onemore thing. I took my van to the Chevy dealer yesterday to have my PS system checked. Asa I suspected, the Mom and Pop auto shop who perfromed the repairs on my van really screwed up and ther're not fessing up to it so I'm now stuck. Turns out that Mom and Pop shop replaced my Power Steering pump and filled with TRANSMISSION FLUID! Does this present a problem now as they offered to drain and refill with Power Steering fluid? Also, will adding Lucas PS fluid improve anything, in your opinion? Lastly, Checy stated the the High Pressure PS Hose was inprorperly installed and slightly bent, but Mom and Pop shops states that that is impossible in that hose can only be installed on way - what do you think? Can improper installation cause any problesm with my Powersterering system? FYI that although the noise is extreley annpoying, the stewering appesars to work just fine, to inlkuce tight turns.   Thank you again.   Mark in Plano, TX Retired Marine Replies to this message: 442dude (Mar 22, 2008 1:32 pm)

Replying to: cyberx1 (Mar 22, 2008 12:12 pm) Hi Mark...Semper Fi !!   Let's break this down...   1. Trans fluid in PS pump - hard to say what issues this could cause, depends upon the compatibility of the 2 fluids...they're both theoretically "hydraulic fluid" and I know there were some Fords that used trans fluid in the PS system...I can't imagine that there's a good way to get all of the old fluid out for sure without dismantling the system...I think I would get rid of all I could and refill with the right fluid and cross my fingers...I'm not going to be shocked if just replacing the fluid gets rid of the noise.   2. High pressure hose - I think my biggest concern would be that there is a kink in it that is restricting the flow and possibly causing your noise...but you say that the steering is working fine...I think if it was kinked the steering wheel would be hard to turn...I've never had to replace ours so I can't say for sure if you can install it more than one way...like I said...I think a kink would be the issue here if you had one.   I'm not a mechanic unless there's a shade tree and some beer around but here's what I would do:   Replace the PS fluid with the correct fluid and do the air bleed procedure... Check the high pressure line from the pump (its the one that comes off of the bottom of the PS pump) for kinks or restrictions.   Then I would see what happens...Honestly, I think the correct fluid will cure the noise...and a little Lucas in there certainly wouldn't hurt either - they make good products.   Let me know how you make out and feel free to post question...good luck   John
