Chattering sound from accessory belt area - Power Steering Pump?
I’m a little stumped on this one. I’ve heard a whining power steering pump before, but I have more of a whining coming from the left side of the engine bay. I can’t see anything or tell specifically where it’s coming from. SOUNDS like the top, which is why I suspect the PS pump, that and I see signs of a small leak, which is why my mind goes there. But again I’m getting almost more of a chatter and not a whine. And I don’t want to go tearing into a pump that doesn’t need it (besides the rings that may need replaced for the leak).
Any help would be appreciated! I could try to post a video but half the time I post pics/videos people have troubles seeing them on mobile devices.

Check YouTube for videos of the sound and compare.
Tensioner pulley seems to be a common cause but compare the ticking
Let us know what you find and good luck.

So I looked a bit closer today. Wanted some input if anyone has any
it does look like the tensioner is fluttering a bit, although the majority of the chattering is coming from higher up. I’m assuming the PS pump like I thought before.
If you look you can see what looks like a washer moving along the shaft that the pulley is attached to that goes into the pump. I’m assuming this isn’t normal.
I’m not familiar with the make up of any power steering pump. Do I need a new one? Do I need a seal or something replaced? Or IS this normal?
Also does the tensioner pulley look like it’s causing anything? Doesn’t look terrible moving but does look like it’s movinf more than it should.
Washer from rom power steering pump at about :10.
Tensioner at :52 seconds
Thanks in advanced to anyone who can chime in!

I have a few pictures around the pump too but I think you can see the same stuff in the video, plus I think my pictures make it to where not everyone can view the page.
But it you can see some fluid “sweating” out from the line near where the pulley is bolted, and where that waster is spinning around

Hi,
As another poster mentioned, get a stethoscope. Place it only on non-moving parts. By alternating where you place the tip (tip is almost foot long so you can place it lots of hard to reach areas), you can see where the noise is strongest. That will lead you to the problem area. IMHO, this is a must-have for debugging car problems. And at 15 dollars, there is really no reason not to have one.
That said, you tensioner does seem to be moving too much. But maybe it is moving to compensate for a problem with the pump. That is why its best to get the scope and figure out the source of the noise.

The sound is coming from the power steering pump. I don’t need a stethoscope for that.
Looking into it a little more I’ll be rebuilding the pump WITH the bearing. I believe that’s the issue is the bearing For the shaft

Hey Ossman and others - I thought I'd share this video I just took after the TL had been sitting a few days while I modded the headlights. I don't think this is the noise Ossman mentions, but in case anyone can identify it, please enlighten me, lol. https://photos.app.goo.gl/Bs5Rf4wZtjWcdxVb9

Just thought I’d give an update in case anyone ever has a similiar issue.
I replaces the belt tensioner, and the issue was NOT fixed. I didn’t think is was the issue, as that’s not where the sound was from. But it looks like it needed replaced so I did it anyways. I ran the car for a few minutes, and the sound was still there, so I went ahead and ordered all the seals and bearing needed to rebuild the pump. The will be here Tuesday.
Then I go to leave to meet my wife’s family for dinner, and as the car is warming up, I hear the noise get worse and then notice some other sound. I pop the hood and take a look under the engine cover. First thing I notice is the sound appears to come from the power steering pump, then under the cover I see the power steering resouvier overflowing with foamy fluid. I figure the pump has finally gave out.
Im assuming the extra tension from the new tensioner did its job and put the stress on the pump, and it couldn’t hold up.
So yeah just wanted to share my experience. Figure the pump needs rebuilt now without a doubt. So will update a little later when that’s done

So I pulled the PS pump off to get it ready for rebuild as I got all my seals, rings, and bearings in today.
I would say my original thought was right judging by the pics. This is right after I took it off. I did not move or break off anything.
Looks like the outer bearing housing separated, and the bearing wore out and the pump failed.
A new bearing is supposed to look like this, the orange piece seemed to have separated off of the old one.
So I have all the new seals and what not. But it looks as if the pump has already been replaced with a remanufactured one, yet it has already failed so I'm assuming it isn't an OEM one. The current pump also is coated black and has a REMFG stamped on it.
I'm pretty hesitant to attempt to rebuild this pump with the OEM seals if I'm correct in assuming this is NOT and OEM pump.
1) I'm concerned other parts on the inside will wear prematurely, the car only has 70,XXX miles on it, I wouldn't imagine this pump has more than half the miles on it.
2) I'm not sure if the OEM seals will be a good fit for a non-OEM pump, if that makes sense?
Wondering if anyone has any suggestions on this? I'm leaning at dropping the money on a new pump at this point

Typically re-manufactured units are OEM units, they just have been rebuilt with aftermarket seals, bearings, etc...Of course aftermarket new units can end up mixed in the re-manufactured parts as well if they end up failing and are used as a core. Regardless the OEM seals should fit without an issue, however that is up too you whether you want to buy new or overhaul this one. If it were me and I already had the stuff I would attempt to fix this one and see how it goes. I previously rebuilt my OEM unit earlier this year and it was really easy.
I am not sure of any markings that would be cast into or etched into the housing that would be an indicator of OEM or not.

Yeah I wasn’t afraid to rebuild the pump, but I decided to go ahead and replace with a new OEM one. Time will tell if it was worth it but hey, I plan on keeping the car for 5ish more years so we will see
That being said the new pump is in, and the car is super quiet. Even more so than before I noticed the chattering sound.new pump was pricey but I’m happy I can drive the car again
