Question Ok, 2nd 'new' PSteering pump is in and...

I installed the new power steering pump (the second one...) and those fittings were perfect (see other thread, https://www.dodgeintrepid.net/forums/...d.php?t=110981no runs, no drips, no errors!

BUT the second 'new' pump also whines like a banshee...it definitely is the pump as the old ear to a big screw driver right on the part will attest to...

I let it run a bit to warm up the PS fluid while bleeding the system, the fluid is now much less milky than before (I guess all the air is outta the system now) and the wheels turn very smoothly...it's just that the pump is noisy as hell.

Could it be that AutoZone got a bad batch of rebuilds? Or is it something else? I thought maybe the belt was too tight but after easing off on the tensioner some, it didn't make any difference.

Any other pearls of wisdom y'all can impart here will be much appreciated

Very possible. Their rebuilt alternators and starters are notorious for being DOA. When I worked in auto parts (not Autozone) I saw plenty of rebuilt stuff come back as defective even when the company was considered a respectable rebuilder.

That's what I'm thinkin'...

Looks like I'm headed to the stealership for an OEM pump...and returning this one to AutoZone...AGAIN

Thanks for confirming my suspicions :icon_cool

How did you bleed it? It can take some time for all the air to get out of a totally dry new pump and drained system.

To bleed, turn the steering wheel lock to lock with the engine running several times (and put some pressure on the steering wheel when you hit the locks to load the pump), and then leave the cap off of the pump with the engine off for at least an hour, or until the fluid is no longer milky, then repeat turning the steering wheel as described and check the fluid again. Repeat as many times as needed. As long as you dont have any leaks or problems in the rack, the pump should be fine.

The other issue is how the pulley gets installed, if the pulley is beat on with a hammer and not pressed on with a press or pulley installer tool, you will make dents in the vanes and pump walls inside the pump everytime you hit it with the hammer, and that will cause it to whine.

Autozone doesnt have the greatest parts, 2 bad pumps in a row is rare. It does happen though, I got 2 bad starters from them a few years back.

I recently went through this same thing w/Autozone rebuilt parts and my pump whines to this day. It works fine just noisy as I-10 at rush hour.

I did what you said about bleeding...except for removing the cap, but the fluid wasn't milky anymore. I did install the pulley with a pulley installer tool, and even had a depth gauge to make sure it would align with the rest of the system.

I really think it's the pump itself. I'm getting to be an expert at this LOL...

Then get an OEM pump, and your money back at vato-zone.

Well...ordered an OEM pump (the parts guy gave me a 20% discount because...thanks 32Intrepid...I gave him a tip about the adapter) and to avoid another 2-3 hours of wrenching, I also got a new pressure tube and adapter for about $220 total.

I'll pick 'em up Friday and about an hour and a half later on Saturday, they'll be installed. Hopefully, no whinin' like a banshee...
