my evo is making some loud, high pitched drivetrain whine right now. it makes it while moving applying power, driving at the same speed, or driving with the clutch pressed in and the car in nuetral. the sound goes away if i take my foot off the gas and coast with the car in gear. it make the noise from any speed.

i just installed a buschur stage 3, dyno flash, exceedy clutch, coilovers, ect. i think it probably is the clutch, but is everyone elses exceedy clutch so loud? or is it something else.

 

ok does it get worse the faster you go.
if so my did the same and its the transerfer case and i recomend not beating or even driving thta much
my car is in the dealership as we speak geting fixed.
warrenty baby even with a act clutch and intake.
gotta love a good dealership

 

Transfer case, most likely. The dealer will blame the failure on the clutch

 

You just blew your ****ty mitsu transfercase, welcome to the club! And don't even think about them warrantying it either!

 

congrats...j/k...damn mitsu and the ****ty transfer case....

 

my dealership put it under warrenty.
dont know what you guys are talking about.
its a brand new car,and they told me a new one is 2300

 

You got lucky. Most people that have had the failing transfer cases usually are blamed by their aftermarket clutch which put more stress on the tcase.

 

what exactly goes wrong with the transfer case, do bearing die, does the case split, does it chew up the gears? instead of just saying it failed, lets discuss what actually happens to the cases. i will go search as well.

 

think my transfer case had bad bearings

 

if just the bearings go bad, that is hardly a reason to replace the whole case. who sells rebuild kits, or bearing kits? also, does anyone rebuild them with better parts, or sell aftermarket cases. i saw the turbo trix thread, but they didn't seem to be building them yet.

i think i would like to go the path of simply replacing the offending bearings.
