driving the evo8 2003 I can hear a slight whining sound that fluctuate a bit its pretty mild really but when ur going low rpm 4th 5th gear u hear it most , the weird thing is I believe i also here it in neutral at times and sometimes it wont make the sound and sometimes it does I'v heard the major death whine can be transfer case but this isnt loud enough to hurt ears but it is loud enough to be annoying at times when its worst not sure and if it is transfer case how much could i expect to spend to have it rebuilt ? appreciate all the help here this is a great website ! was thinking possible wheel bearing or differential i want to say it sounds like its coming from the rear end but i can't tell for sure , recently had the car dyno tested and he never heard a problem but ofcourse it was so loud in there i dont think we would have known

 

Sounds like the T-Case whine of death. Does it only whine when you're on the gas? Is it a high pitch whine?

 

here is your TC rebuild prices buddy

it could be your belts,mine have a slight whine at neutral and through the gears. go in your engine bay when car is running and fluctuate the throttle while near the belt area.

 

thanks guys its way more mild then in that video so not sure but I'm going to have it checked out if it was the transfer case would it still do it in neutral ? cause mine does at times in neutral

 

These cars have a lot of whine. Gear whine from the trans is sometimes audible. I've had t-case death whine. It whines no matter what, on or off the throttle, and is loud. That being said, I recently replaced my broken OEM trans with another OEM unit, and each had its respective "whine" in different rpm's and speeds. If it is not as loud as the video shown I would not be too concerned.

Edit: It also gets louder as you increase load/speed. In other words, if you floor it in 3rd or 4th from around 3000 rpm till redline, does is get progressively louder? If not I doubt it is your t-case. People on here are so quick to say "its your t-case", but how many of you guys have experienced this first hand?

 

mine does the same thing, It has something to do with my powersteering pump i'm pretty sure, its a very faint whine, I can here it if I roll on the throttle, or when I rev it, when I cruise I can here it whine on low throttle from about 2.8k to 3.4k after that, it goes away. It also doesnt make the noise when i'm off the gas. I thought it was the TC too but now I have no clue, I just turn my music up so I cant hear it

 

I've had t-case whine...and it continuously whines not in any certain gear, rpm, on/off throttle...just anytime the car is in motion...so if it's just in certain gears or on the throttle it's probably trans related....not t-case
