Make sure the shifter is selected to FWD before pulling it up onto the dolly.

near impossible to take out of 4wd once the back front wheels are up and the back wheels not. yeah they bind up.....just was thinking back to when this happened to me...

I loaded a 'long been dead' 4wd loyale onto a dolly once, tried to drive away and the 4wd was engaged. Was dragging a rear wheel and obviously starting the engine to get some vacuum to dis engage wasn't a quick fix. I dropped the diff end of the driveline, ratchet strapped it to the exhaust and away I went.
