I've seen the repo man just yank on a 4wd vehicle. Pulled the thing down the street, rear in the air, front wheels just dragging down the street till' he was in a "safe" place to get it in a better configuration. I used to thow the jeep into 4lo when I would park illegally (err... my friend would, I would never do something like that of corse), but now I realize that the effort was futile.
