Transfer Case Replacement [MERGED]

My sources tell me the transfer case that is the US Evo is the same one that was in the Evo 5,6. Its a strong part...
but you guys seem to be having some manufacturing quality issues on a few driveline components indeed.

Anyone consider the lubricant used in the transfer cases as a possible catalyst to the failures? There isn't much in there to begin with, so the quality and quantity of oil in there may need to be considered? Are those that have failing cases still using the factory fill oil or have they changed out to something better that can take on the greater loads, that of sudden abrupt launches? The demands on the oil must surely be greater with high HP/Torque some have and subject the drivetrain to. Perhaps using a higher viscosity oil like 85W-140 in the transfer cases may help? The book calls for SAE90. Most are putting in 75W-90. 85W-140 would still cover the recommendation. Thoughts?

With more than double what it had stock, it's only a matter of time before tranny pieces start to break. Hopefully, by the time the need rises there will be a solution.

Your interest appears to be aftermarket changes to beef up the drivetrain to handle big HP numbers. I assumed the premise for the original post was stock or modest power increases.

Well, last I heard, Ferrarokid had put a front helical LSD in a US Evo VIII and it's been working great for that guy. I think that he's offering it as a rebuild possibility for those that have grenaded their transfer cases.

Thanks for bringing this up noodle, it has been a long known fact in the evolution world that the stock petroleum based Hypoid gear oil sucks...
thats why most evo owners that track or race their car in the UK & the Caribbean, use a high quality synthetic.

I think that nOOdle poses a great question. i know Buschur's response is to use the factory Hypoid GL5 90 fluid as he grenaded two of them. It just possibly may be the fluid that is being used. Very good point nOOdle...

I'm hoping that their failures were due to abuse or a manufacturing defect and nothing else.

Transfer case blown in under 200 miles
New transfer case installed by Mitsu blown in under 200 miles. Sweet. Mitsubishi claims to have some reported problems but has not reached epidemic level perportions YET. Anyone have info on the Lemon law?, as this is the 3rd one and I am not happy

Listen shepard does not build transfer cases end of story !!!!
I am on my 3rd one. The last breaking in under 200 miles . It is a known problem and Mitsu is waiting to see how many break before issuing a recall. This transfer case is for the USA only and was not tested before being put in our cars. We are the guinea pigs.

I'm wondering the bulid date on the cars with blown cases. I'm at 24k miles without replacing anything having to do with the clutch or tranny (knock on wood).
Did they make you pay for it?
