2002 Ford Windstar Repair Question
Ford Windstar Transmission Problem
It's impossible to know without looking at it, but Ford has always had way more steering and suspension parts fail leading to crashes than any other manufacturer and ball joints in particular are nothing to ignore. If you're told they're worn, replacing them immediately is more important than eating. It's a choice between being hungry and alive vs, . . . well, you get the idea.
The wheels are supposed to spin in neutral. If you have both front tires jacked up off the ground they will always spin but in "park" one will spin in the opposite direction as the one you're turning. Based on your description it sounds like one of the half shafts pulled out of the transmission but that usually results in some fluid loss onto the ground. I suppose there could be a transmission problem but that would be quite the coincidence.
