I find it hard to believe some 'iffy' condition would be required for a
mass-producted childs toy. (so you hope)
I have two suggestions.
1) Limit the rotation of the turntable to 180 degrees. (or 180 each
direction) That should keep it from getting stuck when it gets in 'bad air'
2) Somewhere I saw a post where they made a limited slip differential. It
was something like this:
Take a piece of Technic Ribbed Hose ( http://www.peeron.com/inv/parts/78 )
cut it to one stud long (I cringe saying 'cut') and slip it in the
differential before sliding the axles in place.
I'm not sure if it will fit, but that would make it harder for the wheels to
turn in different directions, than to go straight.
