...which one do I have?

Seriously, I bought a 1992 Grand Caravan LE, 3.3 liter, and I have no idea if it's front wheel drive or all wheel drive, and I haven't been able to figure out how to tell. Probably because no one else in history has ever not known this from the beginning.

So, what should I be looking for?

Thanks!

Most common ones are the front wheel drive vehicles. Check under the vehicle and see if it has a drive shaft going to the back and connecting the rear wheels. There will be front axels, left and right going to your transmission.
