You can have 2wd with a 203, but the diff will still turn the driveshaft.
yes, I always wondered why they called the ones like mine an all time 4x4, when you put the indenticator in neutral when you don't need 4x4. and yep the front driveshaft does turn on these. I kinda like tht mine has auto hubs, as it sucks to be out turning hubs when its freezing out or if theyre iced over lol. but by turning the driveshaft, it would get less milage and lil less power, so i geuss theres pros and cons to both.
