Whining noise on 2022

I just got a 22 Tacoma sr with the 2.7 has 100 miles on it, every time I accelerate I hear a loud high pitch whining noise does anyone know what it could be?

 

Is it your wife?

 

windows open?

 

rear diff whine

 

Can you tell where it is coming from (left/right side)? Does it change pitch/tone when accelerating? AT or MT?

You'll need to provide a little more details.

 

Only ATs for the 2022 2.7l.

 

It sounds like it comes from the front it always the same high pitch when accelerating

 

Invisible SC perhaps...

 

With careful consideration and analysist of your trucks symptoms I'm willing to say it'll be a complete write off, best you can do is start parting out now and hope you can make back a bit of what you paid for

 

Other than radio static, there is nothing that would maintain the same pitch / frequency while changing speeds.

Some vibes can change with engine speed while other can change with tire speed. Whistles and such would change with winds speed.

 

Does it "whine" at a steady increase with odometer speed...or does it match with gear speed steps?

 

asking the good questions here

 

Match’s with the gear steps

 

+1 on radio static.

 

Have you ever driven a vehicle with a mechanical fan before. My bet is you are hearing that and are not used to it...

Maybe get a video with the sound. Us keen eared interwebcanics will have you all solved up in no time...

 

That makes me think the rad fan even more...

 

The fan should quiet down pretty quickly with a bit of heat in the fluid, unless it is a bad unit.

For whine matching engine speed, it could be the accessory belt, alternator, or power steering.

 

We need more information...

How are you accelerating, like Gramma Moses or like Meat Loaf, a bat out of hell?

Does it make the sound in park and you rev the engine?

Is there anything that you do that changes the sound?

 

That was just me telling you that I've never looked at the 2.7s without telling you that I've never looked at the 2.7s....

 

From my particular experience with my Taco when it was new going through break-in miles, I noticed a similar whine matching gear steps. I figured it was the serpentine belt and the various pulleys and whatever they were connected to just doing their "normal" break-in wear and also possible tranny whine. Over a few thousand miles it subsided by a lot-to-barely even noticeable.

But back to my initial post...when I first heard the sound...I pretended it was a secret SuperCharger Toyota treated me with...hahaha.
