4x4 NOT WORKING

[4tsparrow]

I have a L4200, and the front wheels no longer engage into 4x4. I have replaced the couplers on the prop shaft and made certain the axle fluid was full, but it didn't fix the issue. While I had the prop shaft off, I did notice that the gear bevel assembly connected to the front axle spun freely. Is this normal? I also noticed axle fluid leaking from that area. Any information is appreciated. Thanks

Plan on a major teardown, rebuild project.

With the front tires off the ground, can you turn the propeller shaft with the shifter in the 4x4 position?
