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?



that's odd. on a slush box, the parking PAWL is what stops your vehicle from rolling. (also, this is why you shouldnt winch while in PARK..., you can break this off -- per marlin of marlin crawler fame, suggestion).

so it doesnt matter if you have a transfer case. the output of the tranny will still be locked.

now, if you parked the vehicle and shifted out of 4wd, then the TRANSFER CASE has technically unlinked the front driveshaft to the entire driveline.

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?


actually it's because of an open diff. remember what a differential does and why it's there.
