Steering noise tsb

Hello. This is the thread I started for my car. http://www.impalaforums.com/autocare...ing-noise.html another person said there is a tsb for other models that includes replacing the rack and ps fluid for a "zip" type noise when the wheel is turned at slow speeds. Does anyone know that tsb number or the details of it? Thanks

Here is a thread I started about this issue:

http://www.impalaforums.com/showthread.php?t=1202466

It contains links to another forum that talks about the TSB in detail...

Thanks.. Can't believe I missed that in the other thread.. My cars been doing it all day yesterday and today, where as it used to only do it when it was cold like everyone else's, hope it's not getting worse. i know you said it's just an annoying sound but have you heard anything about possible damage caused by it? And did yours ever come back after adding the conditioner?

From what I read, it does not cause any "mechanical issues" - it's just an annoying noise. I can't be 100% sure that is true though.

And surprisingly, I have not once heard the noise since removing all of the fluid from the power steering reservoir and replacing it with that Lucas Power Steering Fluid w/Conditioners. I drove the car for over 3 hours yesterday and never heard the noise once (and did quite a few "parking maneuvers", which is when I mostly heard the noise). But, again, I can't be 100% certain it wouldn't come back if it went down to 30F degrees though.

Ok so you replaced ALL the fluid with this? Not just mixed it with regular OEM? Was one 16oz enough or did you need 2?
I'm assuming you sucked all the fluid out then turned whe wheels (with the car jacked up and turned off) to get more out? I think I may try this which is why I'm asking, I asked my friend who's a tech at a gmc dealership and he said no go on the power train warranty covering it, so I'm on my own to fix it.

I simply sucked out all of the fluid that was in the reservoir and replaced it with the Lucas stuff - I used one of those little "syringes" used to administer liquid medication to infants to suck it out. I didn't turn the wheels or anything like that. Obviously, the method I used does NOT replace all of the fluid since there is still a substantial amount of fluid in the rest of the power steering system, but I think that it replaces enough to make a difference (the Lucas stuff does say that it's safe to mix with any power steering fluid though, so no issues mixing it).

You could always do this procedure twice (or even three times) over a few days in order to replace almost all of the fluid. Or, you could just take it to a shop that has the right equipment and let them replace ALL of the fluid. But, since we're not 100% sure that replacing the fluid actually solves the problem (at least temporarily), you may not want to spend the $$ to have a shop do it - at least not yet. I just figured for the cost of the Lucas fluid and the time it takes, it was worth a shot...

I only bought (1) 16oz bottle and probably only used about half of it, if that (i'd have to check the bottle to be sure though).

Ok thanks. I have a electric pump I use to change it and I'll do what you did so there's some OEM left in there... I know it says its compatible with anything but I still like a little of the factory fluid to be I there, and if it fixed your car (so far) then it very well may work for mine.

Make sure to post back with your results! Since my car didn't make the noise all of the time, it's hard to truly gauge the results. I think the issue is more severe for you, so you'll be able to know right away whether it works or not...

So I sucked all the fluid I could out, jacked up the front wheels and had someone turn them lock to lock (engine off) while I sucked more fluid out. When all the fluid I could get was drained I poured the exact amount of Lucas with conditioners back in, started the engine and bled the air..

At first the noise was just as is has been and after a short drive it started to subside but was still there. I parked in my driveway and turned the wheels lock to lock several times. Later I went into town and the noise was present when I went down my driveway but that was the only time I noticed it, even parallel parking I didn't hear anything.. My feelings are, doing a proper flush and fill with this Lucas might be the ticket. I'm also curious about replacing the hose with a larger one and flushing and changing to transmission fluid as the tsb states, just not replacing the rack. Would this be possible without hurting anything? Would it make a difference?

Give it a day or two before doing anything more - maybe it just needs to "work itself in". It sounds like you haven't heard the noise since you left for town, so maybe it won't come back at all anymore....

Regarding your questions - I really don't know the answers - sorry!

Still making the noise! Mostly when the engines "cold" not necessarily the weather is cold, just the engine. Tomorrow I plan on sucking all the fluid I can out of the ps reservoir and replacing it with the Lucas with conditioners again. I'm hoping that more will get mixed in with the oe fluid that's not easy to get out and make a difference. To do a proper "flush" with this stuff would be rather $$, which if I knew it would work I would do. I will report back in a couple days.

How about you? Any changes?

Damn - that really sucks - I was hoping that it worked for you...

I still haven't heard the noise since putting the Lucas stuff in... But, it's much colder out now, so I'll see what happens during my next drive and report back.

Still haven't heard the noise since I replaced the reservoir fluid with the Lucas stuff. Just took a drive while its' 36F out and still no noise. Maybe I caught the issue before it became "permanent" on my car? Or maybe it will come back soon too - time will tell.

Good, glad things seem better for you! I'm a bit under the weather so I haven't hat time to do the complete flush with it, but in the next few days I will and report back.
