Steering help needed

[Damian]

Issue: While turning the steering wheel while moving, I get a loud schreaching noise from the engine bay. Does NOT make the noise stationary or moving at street or freeway speeds. Only makes the noise when Im say parking in a parking stall or making a U turn.

Replaced: Belt (x2), steering pump, steering box, steering fluid (x?), and now the belt tensioner. All of the steering parts are now new or fairly new, steering does move smooth in both directions, no binding or anything like that.

Noise temporarily goes away when I spray the ribbed part of the belt with WD-40, tried it on my last belt. Ive taken the belt completely off, took a wire brush to ALL of the pulleys and cleaned them with soapy water before installing brand new belt. All of the power steering lines are not kinked, the lines do get hot when engine is run for awhile, so I doubt there are any lines plugged. Im seriously at my wits end with this one. Im so close to locking it up in the garage and throwing away the keys.

So, any ideas on what the problem is? Anything Im doing wrong? Or is a book of matches my solution?

[Damian]

Anyone have any ideas?

My truck is the same way, ALL of the pullies are partially to blame. I just ignore it, when it gets really bad i just lube up the bearings

[Damian]

But this is ungodly loud. People a block away can hear me. Just imagine the worst belt squealing you've ever heard, and at least double that.

I'm going to get a new idler pulley today. I'll get a video if the problem persists.

Does it make the same sound when the AC compressor kicks in?

[Damian]

Not sure, I don't have any R12 in the system, so I don't even turn it on.

I changed out the idler pulley and the power steering pulley with no luck. I'm trying to find out if it has a filter, if so, where is it? I'm wondering if it's creating a lot of back pressure.

First part of the first video is while goin about 5mph, second part I'm not moving at all. 2nd video is while pulling into my garage which is a right hand turn.

Replaced so far:
ZQ8 steering box
steering pump
3 different belts (only have 2 now, Dayco and Goodyear, sounds much better with Dayco)
belt tenioner
idler pulley
power steering pulley
power steering lines, from box to cooler then cooler to pump
reinstalled alt bracket
ball joints
Jeep steering shaft
pitman arm
idler arm
electric fan conversion

Everything is straight with each other, checked with a straight edge. The alt, power steering pump and crank pulley were checked.

New thing I just found out. If Im turning and it squeaks (which it will), if I give it just a hair of gas, the noise goes away. Should I change out the power steering line from pump to box or should I just take this POS in and have someone else try and figure it out?

[Damian]

Thanks Paul for your help today. He came to the conclusion that it was my wheel bearing and not a belt issue. He even said it sounded like a belt squealing. So I need to buy a new hub and get it put in. Another $85 to put into it.

[Shaolin Crane]

Call ed's, they can get timkin hubs. I paid $100 for the pair on the mustangs.

[Damian]

I'll try and call them tomorrow. Hopefully I remember to call them after class. I'm only going to replace one for now and replace the other side in a 2 weeks. I want to ask them about half axles too.

[Damian]

Well, it's not the bearing hub. Next thought was front diff going south, oil looked good. Next in line was the xfer case. Then I found something:

The bolt right above the prop shaft that holds the access cover into the trans came loose and was rubbing. Going to eat now then fix the problem. Fuck me, a couple hundred bucks spent and it's a stupid fucking bolt!!

Thanks again for your help over the phone Paul.

That was it, god awful squealing noise is gone.
