Truck: 2005 chevy silverado 1500 (not HD) 5.3L V8 - automatic trans - manual 4WD

 

Now first I already have the greaseless intermediate steering shaft.

I got GM to put it on 6 months or so after I bought the truck new when I heard about it. They fought me since I hadn't even had to grease it yet. But I said to hell with it.

 

I know I have found 50 thousand posts on all forums with all kinds of propable solutions for this problem but I thought I'd try anyway.

I can turn the wheel when stopped left or right without issue when in park. But when going left it just whines and whines so damn annoying.

When parking and holding down the brake pedal alot of times it won't move but somebody somewhere said this was normal so I'll skip over that one.

If I put any pressure at all to the left even if I'm not even turning the wheel it just continually yells at me lol

 

I've tried going back and forth to work out any possible air, honestly that's about it. I was reading yesterday about a heavy duty valve but nobody that ever bothered using it or thought it would help lol.

 

Any help would be appreciated.

 

Thanks,

 

Kenny

I also have a similar issue that I'm still working on. In my case I think it's just the pump slowly giving way. Have you checked the fluid level/condition. Awhile back mine was giving me issues and found the fluid level low and pretty dark. After changing fluid and topping it off it improved performance quite a bit.

I haven't checked it lately, but I did pull out most of it last year and put in some new stuff. But I made sure not to go too low and let air in.

Somebody was talking about additives that can quiet it down but idono sounds like BS, it's only a temporary cover up even if it did work.

 

It's these damn NY roads I sware....my truck ran fine for 8 years in GA lol

Generally the noise is caused by aeration or when the pump is at max pressure. Try to get a good look at the oil in the reservoir and see if you can see any "foam". If you see any at all, then you need to remove it.

 

Are you using ATF or Power Steering Oil?

 

Is the steering effort the same in either direction?

 

I have no idea what you are trying to say in the part about holding brake pedal down.

 

There are parts in the steering box(or chuck, depending on your age) that will dictate the pressure from the pump. Since the noise happens even on light pressure on the wheel, and stops as soon as steering wheel is returned to centered, it sounds like the steering box needs to be repaired.

Yeah brakes have no bearing whatsoever on steering when your stopped - on or off, doesn't really matter.

 

Usually when the pump gets noisy, it's time for a new one.

 

Just went through this with my buddy. Bought an '02 Dodge 1500 that made all kinds of noise turning, but the previous owner told him they put in a new pump .... so it CAN'T be that ... :lol:

 

I told him to replace the pump. Said no way, it's new. I said ok, do as you will! So he replaced the steering rack for about $300 .... still made the sound.

 

He finally replaced the pump. Whaddya know? It's quiet again! :D

That kind of noise is usually the ps pump, or air (as said above). If air, it has to come from the suction side.

Funny how reading something can trigger something. He must have been referring to hydra-boost. Pumping brake pedal puts load on power steering pump(not sure but maybe name changes to hydra-boost pump) and can cause noise. Doubt this is the case here.

So I'm only 90% crazy now ;) lol

Well I'm only driving a 1500 so definitely don't think I have one of those units in there.

Rolled through a parking lot yesterday just idling almost with the window opened, driver side pads are definitely rubbing, touch the brake pedal at all and it's gone.

And I heard some very mild intermittent clunking from that passenger CV (another thread)

 

Maybe I need a mute button for that magnaflow I could troubleshoot these things alot easier lol :)

 

So I'll switch out that axle and caliper this weekend. I have a spare set up calipers and pads down in the basement anyway so if the wear is excessive I'll take care of both sides.

I need an oil change too so I'll take care of all this saturday and save the PS pump for next weekend.

 

I will drop some conditioner or something into the PS reservoir though I think and see what happens over the next week.

Noise is just something that is vibrating the air. If touching the brake pedal stops a noise it almost always means the brake pads are not installed with all the necessary anti noise parts. Make sure you are not missing any anti-rattle clips, special backing plate shims, sliders are greased, and if all else fails, smurf shit on the back of the brake pads will quiet them down.

You may want to verify that the run-out on the rotors is under 6 thousands of an inch as well.

That setup is found on diesels. They don't create enough vacuum to safely operate a traditional vacuum operated booster.

Well these pads came with shims but after about 100 miles they kept falling down and grinding the center of the rotor. I pulled threw 'em in the garbage and put on some "smurf sh*t" lol

I got pissed and I'm sure I pulled them off both sides but maybe I left one side on.....

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
