Hey,how are you doing guys ?
I have acura TL 04, 158.000 miles. I had problem before couple of days,it's noise on power steering. I can heard in morning(cold weather), it's very loudly ! all MECHANIC I went them, they said you must change the pump ! it's take 300$ at least. Finally, I changed the O-ring, and it's work very good.
try to search about your problems before you fix it. Thanks for your time.

 

Was it difficult to fix?

Easy to fix. I get this done a year ago, if the noise its only when its cold you can be sure its the o ring at the pump inlet hose. I have a instructions on how to replace it.

Can the noise be controlled by your turning the steering wheel? If so, it's likely the o-ring that needs to be replaced because air has entered into your system.

 

Not when turning. Just after it's been sitting for a long while or overnight as it shifts into second gear. Like maybe the rpm change is making it happen? I'm not sure. I rhought it was air in the hose but its still doing it after 3 or 4 months. And it only started doing it immediately after the p.s. fluid flush. And it's coming from the passenger side like where all the accessories are located

 

I wonder if there is a way to bleed air from the system or if it is automatic. I know the pump itself is higher than the reservoir. So that could be a hindrance to getting the air out. My camaro had a little bleeder cable on the top of the thermostat cooling system so you could bleed the air out. But not sure if power steering is like that...

 

Sounds similar to a noise I hear on my car. Service Manual says its normal. I only noticed the sound this winter but that may be because I've recently been paying extra attention to every little noise to attack problems early. On warmer days, the sound seems to get lower so I'm thinking it may be some o-rings on the abs modulator getting old, but that is just a guess.

the 1st link you posted is very much like mine. But not the 2nd link. I heard no clicking noise.
I changed the O-ring on the PS pump. It had Zero effect on anything.

But the noise mine "was" making is going away. I can barely hear it now. I think I "might" have changed the transmission fluid too that day that I spoke about. I don't remember for sure. But I have been blending the fluid back to OEM DW1. And that fluid allows for more slipping, so I hear. And it might have taken a while for the torque converter / transmission to get used to it. Or I might have needed for the transmission fluid to wear in. I mean being brand new fluid , it might have caused too much slipping since my car is getting older. I don't know but the noise is going away, almost completely gone. Often I can't even hear it.. It might not even be doing it now at all. The last few times I drove the car, if forget about the noise, and I said to myself "did it make that noise"? And I have said that to myself like 4 times and I can't seem to hear it. But it use to never let me forget about it. It was much louder. So, I think it is gone or going away. And it might have been "new fluid". I dont know for sure because I cant remember if I changed the fluid or not. I do it so fast now. haha

 

I said "it might have taken a while for the torque converter / transmission to get used to it." Because I was thinking only the torque converter. But I didn't know for sure if fluid runs through the torque converter. But it does. So my thinking was right. I think the torque converter was making noise. And this video confirms that fluid runs through the Torque converter.

 

My noise also started going away in the spring and has now gone completely. Before the noise left, I narrowed it down to ABS modulator area using a sound recorder. I'm thinking some rubber seal on my abs modulator does not like Chicago winters (this was 1st winter car was not stored in heated garage). If noise comes back in December, I'm pretty sure that is the problem.

 

Well, mine would only make the noise when shifting from first into second. Like a soon as it begin the shift, I would hear this whirling sound. And it only made the noise for the duration of the shift. But while it was in either gear, there was never any noise. I just think putting oem fluid back in the transmission , blending out the redline racing fluid may have caused tge issue. And also due to the wear and age of the car. But I'm only hypothesizing. I have no solid evidence of the source of the noise. But It never made noise when pressing on the brake. And to be honest, I can't even remember if I swapped out the transmission fluid at the time that I flushed the power steering fluid. But that was when it started that "second gear shift whirling sound". And I don't see any connection with the abs and a 2nd gear shifting whirling sound. Either way, unless it gives me a bigger sign, I may not figure out what it was. I guess I'm ok with that as long as I have no trouble.
if a rubber o-ring or sealer is your problem, then it will likely come back. I'm surprised it even went away if it is related to abs

 

update: The noise is totally gone. I think it was the new transmission fluid I put in it causing weird behavior in the torque converter or transmission during 1st to 2nd shift... I dont drive much so it took a while to "re-adjust".
