I'm building the Unimog right now. The chassis is done. When the pf motor runs everything is fine. However, when the power is set for the front, the axle that goes to the back still turns a bit. When I put a finger on the gear on the back, it easily stops turning, I don't feel much resistance. Is this normal? If not, how to improve this?

That should be due to vibrations. Since the axle for driving the front and rear function is the same and the clutch gear not sitting completely free on the axle. Once you have built the attachments, there will be enough resistance in the drive train of the functions so it doesn't turn anymore except if clutched in.

The idler gear/clutch gear for that function is probably just a little tight, so when it turns without being engaged, there is just a little friction so the axle spins. Same thing happened to me when I tried to build a Unimog.
