Thanks, this is great. Ill probably try that today. Since you obviously have a lot of expertise in this area, you ever hear anything like that sound in my first video?
Anyone recognize this not transfer case sound (FJ62)? (1 Viewer)

Not personally.
isolating the transmission from the engine is the first check i would do if this came in my shop.

Last question before I attempt, is it a bear getting the bolts back in or should it be straight forward since the converter wont be moving, I just need to realign the flywheel again for each one (the first one moving the converter after bolting)
thanks again.
Did you do any of the tests/checks I posted about?

Ok so, in park, and neutral, the sound stops. In drive moving and not moving the sound occurs (when it's hot, but not over heating). Transfer case in neutral in and gear, no noise.
I can't really test separating the torque converter because it cools down too fast and sitting in neutral doesn't heat it up.
i WILL take A HUGE @3_puppies WAG :
- You have a BAD FAN CLUTCH , it continues to rotate after engine is OFF stopped , because ALL the VISCUS Coupling Fluid is now Gone and smoked the main bearing inside .................
- i have seen this at the dealership many times on high mileage trucks and RWD car too TOYOTA ..........
Cressida
Supra
22R & 22RE
3VZ-FE
etc......
take another video of the engine coming to a stop and Engine FAN too same time
please
That first video you took, was the vehicle in park when it was making the nose?
Since the noise goes away with the transfer case in neutral but everything in the transmission (and several gears inside the transfer case) will still be spinning (if its drive), I think we can eliminate the transmission for now.
Does the frequency/pitch of the noise vary with engine speed? What happens if you rev the engine when it's making the noise? Does the noise go away, increase in pitch/frequency, or stay the same?

Yeah so, you are right, today it did not do that though, when I put it in park it did stop, but didn't when I filmed that. 100 percent did even make a peep when I had the T-case disengaged though (but cant put it in park with it disengaged). The pitch does not change when moving I listened for it as I moved and could hear it as I moved, exactly the same as when I'm stopped.
I may try ToyotaMatts theory, although whats the best method there? Run it till I get the noise then disconnect the serpentine belt? Or can I just stop the fan? @ToyotaMatt
It realllllllllllly sounds like its coming from the bottom. I know its reflective but yeah.

DO NOT remove belt
this is a 1 minute visual diagnosis and confirm and Verify step by step
don't over think it right now
just look for the Oblivious............

Lol. Love the help. Ill test this tomorrow, couple beers deep so I can't drive around. I 100000 percent hope you're right! that's best case scenario.DO NOT remove belt

Since the noise behavior seems to be pretty random, I really don't think it's the transmission. It seems like the only real connection so far is the engine being under a slight load (or maybe running at a certain speed).
The next test you need to do is see if the noise follows engine speed. Rev the engine a bit when its making the noise. Does the noise stay the same pitch, or does it change exactly with the engine?
Another good possibility as mentioned is the fan clutch. The fan clutch is about the only thing that will free-wheel for that long after the engine shuts down.

Its... heat related? So its cooling down, so it takes longer for it to happen, but after about 30 minutes of driving it starts squeakin'. Does not change speed/pitch. gonna test the fan clutch theory tomorrow. I know Iron Pig replaced it recently.
another radical Theory is simply one or more of your DRIVE belts belt broke some how and is NOT there anymore ?
old tired died ?
Lost Tension some how ?

Ok ToyataMatt, here we go:we are all dying here for a TECH update ..........
Narrating a bit, it seems like it 100 percent is related to the fan, but on the second clip, the fan stops well before the noise. What do you think? Also the "noise stop - CLICK" WHAT DOES IT MEAN!
