What time points should we be listing at to hear it?

 

I gotta be honest, most of this video is trash. :ROFL: I'm actually going away for a week, and of course I'm not taking my car with me... If this is still relevent when I come back, I'll try a little harder!

 

Try the bar of soap test it will help you find out if belt and tensioner are on way out

 

Definitely something I’ll test out when I’m back!

 

Number of years ago I had a whine in the power steering when the car was at operating temps/warm. Initially thought it was trans noise. Sounded very similar to a SC whine. Eventually nissan/inf came out with a tsb which replaces the power steering reservoir. No more noise!

 

Just dont ever use belt dressing it will make it worst

 

Well, I'm back... This video basically proves my power steering pump is on its way out, making tons of noise all the time... And I thought I was hearing things!! Have a listen, it's audible basically whenever the car is running. (I added some captions with my thoughts at certain points, turn them on!)

 

Finally got around to video of this.
You can hear the squeaking when the wheel turns very slightly. If I go all the way in either direction, it only squeaks when the wheel passes through the 11-1 o'clock range.


The noise only happens when under load, totally silent when its up on jackstands. Also of note, the U-joint where the steering column connects to the rack is rusty but doesn't make noise.
PS system looks great, not losing any fluid or making loud noises.
All boots are intact, no fluid leaks, afaik. And swaybar bushings are covered in thick silicone grease.

Any thoughts?

 

What you are listening to is the the frequency of throttle bodies, those high pitched noises are minimal throttle adjustments as they're adjusting to new load forced by the PS pump straining.

For further diag, try without the AC or with all accs on. Once thing you can do is clean them however after that there is very little you can do.

 

Interesting diagnosis, surprised TBs can make so much noise!. It squeaks throughout whole turns after it sits overnight. Once it's warm, less to-no squeaking. AC on, still squeaks. AC off, still squeaks. Acc, or engine off (no-power steering), no squeaks.
TB cleaning goes on the list! I've been having weird idles anyway. I'll update aafter.

 

Funny enough my wheel squeaks in the first few degrees. The PS whine hasn't improved, and another whine has showed up. Pretty sure its something completely unrelated, so I'm working on that in the background. I haven't inspected my steering gear in a while, most likely once I flip the winters on I'll have a look at my rack and joints.

 

Did you ever figure out what this was for sure? I have the same thing but for the most part its only in the 1 to 2 oclock range. Mine only seems to do it when I'm in motion and turning right though. Can't mimic the sound sitting in park
