There is a loud hauling/whining noise that sounds like a fire truck siren. The noise starts when I hit about 20 mph and continues to get louder and higher in pitch the faster I go. It does not matter if the car is in gear or not; or if I hit my brakes. As I come to a stop the noise gets lower in pitch and I start to hear almost like a soft grinding noise. The sound level of the noise dies off a little at about 70 mph but then comes back very loud as I increase my speed. I have a 2004 evo 8 with about 70,000 miles on it. I talked to some techs and they think it my front transfer case is out. But I want to see if anyone here knows what is wrong or it happen to them. Thanks everyone.

 

No doubt it's the transfer case.. the techs aren't lying, whining noise = your transfercase going out.. either have it rebuilt by shep or get a stock one. It costs about 2k.

 

Sounds like the transfer case go to youtube they have some vids of tansfer cases with the whining sound posted up. Goodluck

 

I'm going to be optimistic and say it could be a wheel bearing???

 

What is happening inside the tcase that makes the whining noise?

 

tcase is fuct. better save up 3500 bucks for a new one.

 

something broke into 100 pieces and they are rubbing together.

 

I thought shep rebuilt them for 1000 bucks??

 

It will be 1200 just for the ring and pinion
Your TC is done.

 

Get the stage 2 from Shepracing.com and it will never break again. I think total is 1700 for stage 2. You just have to ship them yours they will send you a box that it will fit in perfectly to ship. Good Luck man.

 

So you could do the stage 2 and get that option off adding the ring and pinion, and then be set right?

 

Just like everyone else said its ur transfer case its history and just like everyone said cant be shep trannies or transfer cases lil pricey but totally worth it

 

call shep. they will give you prices and explain everything to you

 

Mine's on it's way back from Shep now, came out to 1600 (stage 2 + ring and pinion r/r) after I grinded my pinion until it was a smooth cone. lol.

the whine wasn't as loud as you are describing yours to be, but over time it may have turned out to be that loud.

 

i bought a totally new one stage two. it was like 3800 installed. then shipped him back my old one for a credit. install was like 600. i payed a little more for a new one to save on down time. mine was down for like 6 hours lol.
