My IX does that as well, from ~2k-3k RPM in 1st gear, more noticeable at partial throttle. If you give it a lot of throttle it goes away, but "cruising" from 2k-3k will produce the whine in first.

It's done that since it was new though, so I assume it's "normal".

 

Is the transfer case going out on an 03 Evolution inevitable. As someone in the market for an 03 this is a very eye opening thread. I don't own an Evo yet but this makes me nervous. Did you guys just get hit with bad luck or is this normal?

 

most ring and pinion TC failures(which causes the famous whine)are from not enough fluid or the wrong fluid being used. just use the stock diaqueen, change every 10K or so, and it should be fine. most of the time drag launches will bust the diff in the TC, not the ring/pinion. shep does have the ability to rebuild bad ring/pinion TC's now though so you no longer have to buy a whole new case.

 

so why can't i open the files? I have QT installed and extracted all files.

 

 

I have Quicktime, then unzipped the file i Dl'ed from the link and the files still won't open.

 

 

Files don't work for me either, and I usually can figure any file out.

BTW my 05 with ~55k miles got a small fluid leak on the transfer case and started making tons of noise. In a very short period of time (50 miles?) it pretty much toasted itself.

 

oh crap. sounds like my car...just got a new exedy twin plate installed a few days ago and now this sound just started.....aaaaa!

edit - what usually causes this? I only launch my car at autoX events, that's it...is it hard launches or hard/bad shifting or...????

 

 

My car makes a noise but it sounds like the serpentine belt. It is a whistle and only comes on under WOT. At part throttle or "cruising" it doesn't make a sound.
I would like to take it to a Mitsu dealership but the closest one is about 80 miles away. I will try to get a sound clip of it to post it and compare. Since you were the one doing this I figured I would ask you if it sounded like a belt before it started the death whine. Since sound always loses something through camera phones.
Where did the noise sound like it is coming from? The noise on my car is coming from the right front. I don't think the tcase is there but like you said the noise can travel through the drive shaft. Thanks for your input

 

At times it sounded like it was coming from everywhere and a mechanics stethescope was needed to see exactly where it was coming from. I would try to listen carefully and think it was on the right side one day but the left side the next. If it is your serpentine belt check to see if it is damaged in any way. You can also spray some WD40 on the belt and see if it goes away for a little while. If it does , its your belt.

 

Can someone else host this file? I can't seem to get to it to download or listen to it.

 

Hmmm...did a little experimenting with my whine last night and it only seems to happen at high speed, 3rd gear and up, and under high load. At 220+ km/h it does scream like the OP's vid but during normal driving, nothing and its much quieteer under decellerartion.

Not sure if it is transfer case Death Whine per say but it's definitely something to do with gears so getting the fluids all changed ASAP in any case and we'll see.

BTW, saved one of the OP's vids in MP4 format, hosting it on my photobucket account. To view it just download VLC player (which opens *everything* except WMV files - veryuseful little app) , takes 2 minutes.

linky - death whine vid

edit: sorry, it encoded away the visuals but you still have the sound

 

That sounds like my whine when it first started and now it is in every gear at high load. And under decel there is the normally tranny noise. If it gets worse I will let everyone know. I will have some clips soon. Thanks for your help
