drive an awd eclipse without a driveshaft

[etay89]

I don't think I've seen this question asked before and its purely hypothetical.

Is it possible to drive an awd dsm WITHOUT a driveshaft or would that mess up the front and rear ends?

With a welded center diff, you'd be just fine driving without a driveshaft. That's how AWD cars dyno on a 2wd dyno. You could also use a VCE, but I'm not sure if it's OK to drive on one for any extended period of time (I have zero experience using one).

you wont. at least on my fiance's gsx when I tried to get it in the garage. It wouldnt move at all. maybe it will after the VC heats up and locks up, but i didnt try that

^This is what I'd expect, a couple of minutes or less in gear spinning will sharply heat lock the VCD but it will cool and free-wheel again after a short period. With the stock viscous coupling type center diff, you run the risk of burning it up depending on how far you go with the car. If the center diff is welded or using a VCE, then you should be okay. Just remember the torque is going to find the easiest path out, whether it's through turning the front wheels or through destroying the weakened diff that has undergone several miles of continuously heating-locking and then cooling-releasing repeatedly.
