1980 chevy k30 transfer case

[zlssefi]

I want to see if you guys might know what the problem is here. I have a 1980 chevy k30 4x4 with the cast iron transfer case. Recently the truck started coming out of 4x4 while going in reverse, it does it randomly...any ideas?

Busted tranny mount? Linkage sloppy/out of adjustment?

Cab mounts rotted, cab dropped, hitting shifter? Oh, and it is an NP205 transfer case.

i figured it out, went under the truck to take a look and grease everything and the nut that holds the output yoke was gone. The spline shaft and driveshaft are ok, but the nut was missing. i opened up the case to make sure the gears are in good shape, everything checked out ok, new nut, new washer some loctite and were up and running..thanks guys!
