I just got a Kubota l2250 4x4 in good shape but the front axle was messed up. I just put all new bearnings, seals,gears,ring and pinion. I have put it all together the problem it there is one is when you lock the 4x4 in the drive shaft locks in like it should but both wheels turn instead of locking it like the driveshaft. I didn't crank it up and the front end is jack up.When I spin it by hand it make some clicking noise like gears.Should it be on the ground and running to work right? I'm new to this so I don't know all the right words or if I am making since.
