Whats up folks,

So, the infamous "Death Whine" started yesterday AM on the way to work. I took the day off today and drained the xfer case. No chunks in the fluid, but lots fine metal on the drain plug (groove was filled and about a 1/8 inch mound on top of that, refilled with diaqueen, drove around the block and drained the fluid again, no chunks but more fillings, not as much as the first drain but the groove was filled, but I only drove about two miles. Re filled again with diaqueen.

Now the question, has anyone else thought they had the death whine, that turned out to be something else? and if so what was it?

It seems to be at it's worse between 60 and 80 light load or off throttle, does not go away if I put the car in neutral and coast, in fact it seems louder (propably cause the other drive train and engine noise dies off).

 

Usually the death whine is speed based so if it gets louder from 60-80 then I am afraid that is what you have.
Had you been launching the car lately or go a long time without a fluid change in the transfer case?

 

damn. yea i defanilty have that. any ways to fix it or quiet it?

 

It's commonly caused by damage to the ring gear..such as hairline cracks. The only way to fix it is to replace the damaged part(s). For some reason nobody makes just the ring gear yet. Someone needs to try to get something going with Richmond or another gear company

 

I know everyone says this but, no I don't launch the car. Never been to a drag strip and I have a stock clutch in the car with 30,000 miles on it.... I think I went too long on the fluid and was running the wrong stuff, I know I was running shockproof, but I don't recall if it was light, medium, or heavy.

 

This might have slowly killed the ring and pinion. The transfer case is pretty fickle about the fluid and the top rebuilders will tell you only to use Diaqueen.


Unfortunately, like broeli said, the only fix is a rebuild. I have a feeling we will be waiting forever for a gear company to hook up the import crowd.

 

You got the death whine.................sorry to say.

 

Well thanks for the feedback, I already planned on ordering a new tc with helical lsd in the AM, but just wanted to see if anyone else had thought they had it when it turned out to be something else....

 

so evo x-fer cases cant run redline shockproof? why not? even the light shockproof? thats just too bad, redline is good stuff

 

sounds like tcase is done, call up shepherd racing...mines there right now getting beefed up...

 

Well, some people think Redline Heavy Shockproof is just fine for the TC.

 

Screw the transfer case in our cars seriuosly. I am about to be on my uh,
lets see, stock (went out at 30k),replacement out 1k later (bad shim),replacment - then rebuilt (tre w/lsd) - 70k its on its way out now.

This will be the second one I have had to purchase - my wallet hurts.

There's a little more to the story but I don't want to turn this thread into a ***** fest about mitsubishi service techs.

 

im scared outta my mind when this day comes! i hope it never does.

 

The only thing you can do is buy another transfer case, and have the new ring and pinion cryogenically treated before usage (to strengthen the metal). Also have the transfer case shimmed properly, the OEM tolerances are the best for high horsepower use.

 

On a side note, I have a strong feeling an aftermarket ring and pinion is about to come out =)
