All Evo transfer cases don't whine, if your Transfer is whining more than likely it is going out or low on fluid your transmission is the one that has a slight whine in lower gears 1st and 2nd mainly and is totally normal. I just got the whine again but this time it is not from my Transfer its my pressure plate that is loose. When I installed my clutch I did not have a torque wrench so just tightened till I thought was enough.

It is very common if you abuse the **** out of it, I.E. launching it all the time, using wrong fluid and obviously running it without fluid at all. MAP and Shep Transmission have pretty legit upgrade packages and rebuilds.

Out of curiosity, what are symptoms of bad wheel bearing? Does it makes similar whine noise?

Wrong thread!!!

Never had it happen to me but I believe it clicks when driving or turning, put your car on jack stands and turn your wheels manually see if you can here clicking coming from the wheel bearing.

My rear diff just got replaced and the noise is still there. So more than likely my transfer case is on its way out also? its a low whining noise and can hear a loud grinding noise every now and then.

a lot of whine is coming from the rear. I just got someone to replace my rear diff and is it possible for the whine noise to go to the rear from transfer case, down to driveshaft to rear?

Yes,

It's very hard to tell which is what when the rear diff and transfer case break. I got off the dyno last year and immediately noticed a grinding noise coming from the back of the car. I was more than sure that it was the rear diff so I bought a used one on here(oil looked ok from the TC). After replacing it the noise was still there at which point I realized it was the dreaded transfer case. Here is the noise that I had when it was blown. Does yours sound like this?

the noise is noticeable when driving at cruising speed and decel like yours. I was like you and thought it was my rear differential. mine had metal shavings in the fluid and low on oil due to a small leak.

Mine RA do a clutch sound when desacel and boost in short time, but just when the car is hot.
Can it be T-case too?

If I drive jsut for some minutes, don't make any sound, but when it's hot (Driving in a highway or running), got this clutch sound depressing fast, like in manual car.
