Help identifying noise

Hey there! First post, been surfing for a while and just got myself a 2000 4runner limited in late December.
I have heard a noise and it really only happens at idle. Would anyone be able to identify the noise?

At idle (and in park) try turning the steering wheel left and right more than 1/4 turn. Does the sound change pitch or volume?

 

No it doesn't make any extra noise when I turn the wheel, I was also thinking power steering

 

Belt, pulley, fan clutch? You may be able to use a stethoscope to pin down the source

 

I was thinking possible idler pulley. Just never heard this specific noise. I was a bit worried it could be oil pump as I've never heard one that's going bad.
Can anyone eliminate that? Everything runs well, no over heating etc. Only symptom is the noise I guess I just worry as it's a new to me vehicle

 

I had a not so similar sound coming from under the hood that seemed to come from the P.S. area. Would always quiet down though once the engine warmed up. Had a lead tech at the dealership I go to (and trust) checked the fluid flow for signs of cavitation, brought out a stethoscope but didn't use it. Said it's most likely the Idler as they've seen a good number of these cases come through their facility. Had them replace it (30 mins) and I was on my way, no chatter squeal thereafter.

 

Looks like I'll have to remove the belt and spin them by hand to see which it is !
Thank you for the input !!

 

It's the shriek of aliens who turned your neighbor's house upside down.

 

Bahahha I knew UFOS were real

 

UPDATE*** this noise seems to only happen when I have 4wd engage!

 

Also it creates a burnt smell kind of rubbery

 

Can anyone confirm it's the transfer case bearing?
Can I keep using 4wd till I repair it or should I only use 2wd

 

Clutch or automatic?

 

Auto !

 

Dang. So much for the smelly clutch theory.

 

The smell are my front brakes

 

Your brakes wouldn't smell at idle.

 

No haha I figured out the smell is not associated with the noise. My rotors are warped and shake when I brake. After driving they smell. The noise and smell are unrelated

 

But my clutch, on the other hand, DID smell at idle once it started going bad. But that won't help you.

 

Agreed and nonetheless I appreciate any input given! Best community out there
