I just bought the Ridgeline and it was screaming when I bought it so it is definitely not a situation where the pump was fine, then after flushing it I let air in it and it's now loud. I don't see any foaming in the reservoir. Starting to think the bearing is bad on the pump. As far as function it works perfectly fine, just loud as hell!

It is a second vehicle so I could have it down for days without issue. You have a link to the rebuild kit and any other guidance?

Thanks again for the help. Much appreciated!

Sorry for not getting back.

Honda for the rebuild parts if you wanted to do that route. Would be cool if you took yours apart if you were so inclined and post pictures. If there is any obvious failure.

If you wanted to just swap it in and out I would go to napa. In my 20 ish years of working on cars and my dads 50 ish....I havent had a napa part abnormally fail on me.


Here is a link to the breakdown

Thanks. I may just go the NAPA route. I'm afraid if I tried the rebuild, I would run into problems where I need a tool I don't have.

I've tried everything so I guess it needs a new pump although it works fine other than the very loud noise. I may go to the dealer to get something like an alignment done and see if they confirm it needs a new pump.

i did the lucas oil too. it took a few fill ups and driving,then add more. after about 5 trips it went silent. no problems or noises for 6 months now. this was on a oldsmobile(daughters). just wanted to give you another vote for lucas and maybe try it a little longer before punting. good luck

I am not impressed just because it's a Honda OEM part. Local Honda dealer replaced the PS pump on my 2003 Accord at a, as expected, premium price. 2000 miles and 13 months later (i.e. 1 month out of warranty), the pump failed, and the dealer refused to return three calls I made to them. Surely, a new Honda PS pump should last more then 2000 miles... well maybe not. I then had a trusted independent mechanic replace the PS pump at a significantly lower cost, and THAT pump has a lifetime warranty. Guess where I'm taking my Accord and Ridgeline in the future?

My 2014 Ridgeline P.S. pump started whining at 18,000 miles. Since then I've changed the P.S. pump twice, changed the P.S. fluid 4 times and completely filled it using Lucas P.S. fluid on the 4th flush, replaced the P.S. fluid reservoir bottle and cap, the inlet & outlet O-rings, the return hose, the idler pulley and the serpentine belt and it's still whining.
FYI, The O-ring fix that's out there is only for the 2006-2011 Ridgelines, I just checked and it seems Honda uses a different power steering pump on the 2012-2014 Ridgelines which explains the different O-rings size used on the power steering pump inlet joint. The power steering O-ring size for the 2012-2014 Ridgelines is (14.8X1.9) Part# 91345-R70-P01. The O-ring size for the 2005-2011 Ridgelines is (13.0X1.9) Part# 91345-RDA-A01 which is the same size O-ring & Part# on the 2005 Accord TBS#07-086. So the accord TBS does not pertain to the 2012-2014 Ridgelines. I also noticed the power steering pump diagram for the 2012-2014 Ridgelines shows that it has a lot more internal O-rings which could wear out causing more air leaking problems. I guess that's why it's not being used on the G2 Ridgelines.
Has anybody with a 2012-2014 Ridgeline been able to find a successful remedy for the whining power steering pump besides the ones I've already tried with no avail?
P.S. Besides the whining noise, the P.S. seems to be working fine.

I believe the G2 RL has electric power steering.

My question to you: was all this work done under warranty?

Can you be a bit more specific about your whining noise. Can you hear it inside the cabin? Is it only when turning? Maybe even a sound clip . . .

I have a 14 Sport with about 30k miles on it and it doesn't make any unusual power steering noise, at least to my ears.

How old was your truck when it started making the noise at 18k? Was the pump replacement done under warranty?

My 07 RT with 142k miles sounds very much like Katrina's Ridge. I've cleaned my PS reservoir, did a partial fluid change,replaced both o-rings, but I still get a whine.

In the cold mornings, my PS pump whines as well, but everything works fine. The whine is pretty loud, but I can't hear it from inside the car. By the time I get to work the whine quiets down.
If it's below 20*, then my PS growls within the first minute of driving. I don't plan on replacing my PS pump as long as it drives the way it's going.

FWIW, my PS whine and "growl" only happened recently in the cold weather.

I'll work on taking a video for anybody interested in hearing the whine.

The two P.S. pumps and idler arm pulley were the only items replaced under warranty. The other parts were replaced by me, because after the 4th time bringing it to Honda to try to fix it, the service manager said he didn't know what else he could to fix the problem and was not going to replace any more parts to try to remedy the problem. Nice how they stand behind their product........

It would still be good to get a clearer description of what, how loud, and when the whining noise occurs.

If it is related to the power steering then the remaining area of concern would be the rack itself. This is an expensive part that is time consuming to replace. If you have a record of the original issue occurring during warranty then you should have a good case for having the problem corrected under warranty.

If you are having issues with a particular dealer then perhaps you should take it to another? You should be able to get your previous service records if you don't have them on hand. You can also get Honda themselves involved if you haven't already. The dealership and Honda are two different things.

Good luck!

The whine get's louder when I turn the steering wheel and yes, it can be heard from inside the truck as well. I suggested to the Honda service manager if he would replace the two P.S. lines coming from the P.S. pump and or the rack and pinion and like I stated before, he said he was not going to replace anything else. Since then, my Ridgeline's warranty has expired (not that it did me any good having it) and I tried reaching out to American Honda and all they did was give me the run around for 6 weeks, to finally say to me, they couldn't do anything because all Honda Stealers are independently owned, REALLY!!!
I had the opportunity to talk to one of the Honda techs working on my Ridgeline who said to me, this is a common problem with the Ridgelines because the P.S. pumps used were poorly made, but I couldn't repeat that conversation to his service mananger in fear the tech would lose his job because he was the only honest person there. I tried taking it to other Honda Stealer's who did nothing and just said either they couldn't hear it, or that it was a normal characteristic of the vehicle, the same B.S. they all say when they don't want to fix something under warranty.
FYI, I tried to upload the video I took of the whining noise I'm referring to, but it didn't allow me to upload it, because it doesn't accept m4v video formats, so instead here's a youtube video link of someone else's P.S. pump making the same exact whining noise mine makes.

At the risk of making you repeat yourself, or taking a step backwards, have you confirmed that the whine is actually coming from the pump? I see mention of a tensioner pulley change, is it possible that another pulley, or the replacement, is the source of the noise?
After two pump replacements, you'd like to think (hope?) the pump would no longer be the issue.

I used a poor man's stethoscope (Long Screw Driver) and placed it against the P.S. pump and the screw driver handle, up against my ear and I can really hear the pump screaming away. Also, every time I replaced the P.S. fluid, it would be quite for the 1st few minutes when I would start up the truck before the whining would return, so that rules out the tensioner pulley, since the noise isn't instant after the fluid change. To me, the whine sounds like the P.S. pump is taking in air, but Honda nor I found were able to find any leaks. I looked at the P.S. diagram in the Honda shop manual and it shows the P.S. pump with multiple internal O-rings that could be leaking internally. But like I mentioned earlier, the pump has been changed twice by Honda. Could both P.S. pumps been faulty or is it just a manufacturing defect that made itself present after 18,000 miles?
The P.S. system diagram also shows the system runs to a P.S. cooler and the other end to the rack and pinion system. I don't think it's the lines coming from the P.S. since they're bone dry with no leaks as well as the rack and pinion. As mentioned earlier, this perticular pump was only used on the 2012-2014 Ridgeline's and then the geniuses at Honda did away with it and went with the electronic steering system on the G2's. I don't want to get rid of my Ridgeline as the solution to this problem, because I know there's a solution out there. And I know I'm not alone with this issue.
I had a 2006 Ridgeline before this one and it was plagued with issues, that I was able to resolve myself, which Honda was never able to fix, so I don't want to let this one go, without resolving it. Any solutions or logical suggestions will be greatly appreciated.

I'm not doubting you, but it would be preferred if you would take the time to upload the Video to Youtube and then embed the video in either your original post or a new post?

Additionally have you tried a Hydraulic shop or Independent shops locally? Starting with Talking to them (basically interviewing them) for quotes on a solution and warranty of the work for a solution.

Also it's really hard for anyone to recommend a shop we trust with your profile providing no "Location" information...

Below is the link to my Youtube video I took of my 2014 Honda Ridgeline P.S. whining noise.
Also regarding your question on where I'm located, I'm located in Bergen County, NJ. Any suggestions regarding a fix or recommendations on a reputable skilled Auto mechanic would be appreciated.

Your engine bay is very clean!

But that whine.... Was the rpm fluctuating? It sure sounded like it. That is also an anomaly and shouldn't be doing that.

One easy thing to try is spraying some water (spray bottle) on the accessory belt while the engine is running. If it is a belt / pulley then it should change / eliminate the noise briefly.

A bit more involved would be to remove the belt entirely and run the engine briefly to see if the noise is gone. It should be if its related to the power steering system (or alternator for that matter).

None of these tests should cost a DIY person anything and would be a way to confirm that it is related to the accessory belt system and its components (including the power steering system).

Honestly if the pump has already been replaced then that makes it very questionable that it is the source of the noise. . .

Is it air leaking into the system through one of the hose connections? If it is a high pressure line then it would be leaking fluid not sucking in air. That leaves the feed side of the pump; basically the line between the reservoir and the pump. This is an easy replacement although it probably isn't super cheap.

Has the reservoir been changed. That's an easy and inexpensive swap that can sometimes solve whining issues due to fluid flow impedement. The built in strainer can't really be cleaned properly.

Was the pulley swapped over to a new pump? Perhaps the pulley is bad? If the pulley is bad the sound might change during a water spray test.

Was the proper PS fluid used? Dealer's can be idiots too.

Is it the rack itself?

Is it the alternator? I know you say the sound changes when the wheel is turned so this is unlikely but . . .

BTW, my 14 is nice and quiet at 30k miles. I haven't seen an epidemic of 12-14 owners reporting power steering problems on this forum.

PS: I reread your posts and saw that you replaced the fluid, reservoir and return line already. That leaves the ? as to the pulley on the pump, and the serp belt system (including tensioner). Try the water test.
