That should about sum it up. I went with the shep 3 case build because I was refered to them by TRE when they were out of t-cases, so make sure you give em' a call first.

Every time you lift off the throttle above 3k rpm in any gear above 2nd, it will sound like marbles rolling around in a can. It will be loudest in 3rd and 4th gear. Coincidentally, a normal TC will make the same noise during downshifts or just lifting off the throttle but isn't as loud and doesn't carry on while the engine revs down.
My 03 Evo never had a good transfer case. The last one I had in the car I babied it and got ~18k miles and the entire 18k miles it sounded like ***.

when theres a problem with the transfercase its gets a really loud whine. It starts quite and only around 60mph. then it becomes throttle dependent and REALLY loud. When you apply throttle the pitch will change. The sound is like what 1st gear sounds like but at highway speeds.
Thats how you know you transfercase is going bad. Marbles rolling around in a can is what detonation sounds like. I've had a extra Transfercase for a long time now and still havent changed it cause the noise isn't that loud yet.

In 03 people weren't breaking these things yet. It wasn't untill people started changing fluids and junk when the transfercases started goins south.
Just because the dealership did it doesn't mean its right. I watched a mechanic at a dealership put sparkplugs in with a 1000lb impact. yeah.
Evos have decel noise. But your rocks in a coffee can isn't your transfercase. I don't see how it would make that noise.

When I talked to shep about my blown T-case I was told that the ACD operation was more than likely the cause for the failure. (broken input to carrier) When the system see's excess wheel spin it applies the clutches to compinsate, on a hard launch where you get good wheel spin it locks the clutches quickly and puts a ton of strain on the carrier. That extra shock is what took out mine that's why I'm going to a quaife!
I don't know if I buy that.. There a lot of factors that come into play causing you to break the T-case. IMO a Quaife will lock just as hard as the ACD would.. The only different is the ACD may lock after the E-brake goes down vs Quaife locking right away.. You could always pull the fuse at the track or pull the switch so that ACD is active at the launch. That may help
Wheel hop (different variable can causes that), Not preloading the drive train at the launch, too aggressive clutch and just not respecting that.
When I was launching the car at Norwalk.. I saw some videos of my car spinning the hell out of the front tire way past the 60 ft.. I was on slicks. Slick with big sidewalls will give a little and help prevent some of the wheel hop. The worse thing you can do is slap on a low profile tire or even a very stiff sidewall tire and go drag race. That will break everything.

the TC whine is different then the clutch chatter correct? I believe it's my clutch chatter/flywheel that makes noise occasionally under load going up hills and stuff. And the noise comes from the front of the car.
