Did a Launch in my 4wd Evo 3, and then BOOM Instant Rear Wheel Drive
So i did a search on the forum, did a google search with the tags evolutionm blown drive train rear wheel drive... and did a general google search - No luck.
Anyways... Lined up for the quarter mile at the drag strip, launched at 6500rpm and once i slipped the clutch to blast down the quarter mile, what was expected to be a grippy 4wd launch off the line ended up with all 420Kw of 4G63 fury transferred only to the rear wheels.
Obviously I've blown something in the drive train, what is it? Didn't hear anything go bang or snap either.
Definitely not the axles or front diff, otherwise my car would be behaving like it had a slipping clutch. So might it be the center diff or something else? Can someone confirm?
Car drives normally, but when traction is broken, rear wheels spin up.
Any help is much appreciated.

problem is twofold.
only way to have rwd only is with centerdiff locked and no fwd . if you have no power to front axles then you either have a broke axle or broke front diff.
if you dont have a broke front axle then both problems exist in the trans. so trying to determine problem is mute. you need a tranny rebuild.

When you break stuff in a awd its usually the input shaft, and or the drive shaft one way or another. In all my years of driving awd cars I have never seen anyone break the car so bad its only rwd. Most of the time if you blow up the t case or whatever it just allows the car to be fwd. As 94AWDcoupe was saying you may have killed the axles causeing the t case to lock up some way at the front diff. I would pull the t case and have it inspected to see if anything broke. Starting there if its all good then move to the axles. Somehing broke if your not getting any front wheel movement.

I did this on my 1995 TSI AWD. Get it fixed pronto as the car isn't designed to handle 100% RWD. Mine was amazingly fixed for free by Mitsu as it was a TSB way past warranty too.
