Since I had the rear driveshaft out anyway to resolve a noise (still unresolved), I figured I'd play w/ driving in front wheel drive.
2 things surprise me, hoping someone can shed some light...
Aparently Park (auto tranny) doos not clamp down the front driveshaft? Why not? Is the transfer case engagement not "after" the transmission?

When driving on the front axle only, if I hit the gas from a step, it will pull hard to the left and spin the tire. Differential is open. Why? A buddy suggests it's b/c of the different axle shaft lengths, by default more resistance on one side that other, so the power does not shift evenly. I find it hard to believe such a small difference would do this. Thoughts?
