Squealing / Chirping Noise when driving and warmed up

I missed that it doesn't happen while idling.

 

Yeah, but now I have funny pictures in my head of a lady driving down the road with the hood open and a stethoscope on her head lol!

 

Ha. Yeah, not recommended while in motion!

 

Yes she needs to be moving to hear the noise

 

Sounds wind related.
Have you checked that single crossbar you have on the roof?

 

Brakes. Check all disks: raise the vehicle, spin fronts and look for drag, put gear selector in neutral, then spin rears. Don't forget to check parking brake drums, if dragging adjust using flat head screwdriver. I'm almost 100% certain based on your sound clips you have low thickness on rear caliper or drum shoe dragging (those will make such sound if glazed due to constant contact and heat). G.L.

 

Thank you so much for your suggestion, I will chat with my mechanic and see what he can do.

 

My climate control makes a similar noise, bugs the shit out of me

 

Oh my, how does that make that noise? It is driving me crazy. I am going to be selling it as my new one has arrived. But I really need to get rid of that noise. I have spent almost 6000 trying to find what the noise is.

 

@Ahilton1 new blower motor, Easy swap

 

Can she unplug to test/confirm?

 

yep you can unplug it to confirm. Or you can just turn the climate control fan off

 

Pull the blower motor out and spray it with some silicone lubricant where the squirel cage spins on its axle housing This might quiet the squeaking long enough to sell it.
My 2012 fan makes this noise on medium speed. Don't hear it on the high setting.

$6000?? I have to say on behalf of the group, sorry this happened to you. All of us hate to see this kind of wasted time and money. Stay active on the forums and let us know how your new 4Runner is treating you.

 

thank you I will let my mechanic know to try this. I have a list of stuff for him to look at. lol

 

Fingers Crossed today as my baby is in with the mechanic to find and replace a few more parts to try and find the noise. Lets hope we fix it this time. Have a wonderful day all.

 

Good morning all, I am a happy camper today. the noise is gone just gone. We found that it was the Transfer Case Companion and Output Flange Seal. NO more noise woohoo

 

So how did they fix it?

 

Congrats. Gives me hope for my similar noise that is driving me bonkers.

 

Kind of sounds like it was expensive. Wonder if the transfer case had to come out for this.

 

I agree. I hope he lets us know what hey changed and how much it cost. @Ahilton1

 

He already said companion flange and seal. So they either replaced just the seal, or they replaced the companion and the seal. Not that hard to figure out.

 

Like I asked, what did they do? Did they replace the seal or both. I also asked the cost involved. Since you are not the OP I am not sure why you are commenting.

I'll disregard your comment "not that hard to figure out" since it seems to be said in a derogatory way.

 

I'm more interested in how they found out that was the cause...

 

Put it on lift, drive it up to speed, listen for noise.
