Lack of fluid?

So a while back I noticed that my rear output shaft deal was looking pretty moist. Never noticed any puddles ( granted I don't always park in the same spot) found out the hard way, I cannot engage into 4wd. I can pull the lever, but it stops just before engaging into 4 hi. (And I cannot go into 4 hi, neutral, or 4 low.)

have you checked the fluid in the transfer case? i was having issues shifting the yj i just picked up but it was because i was missing bolts on the transfer case shifter and it was throwing everything out of adjustment. but definitely check fluid in transfer case

No I haven't checked the fluid yet, suppose to be like -20 with wind chill today... And I don't think mine is the shifter, it use to work, but I haven't used it in months.

little different situation but i used to have a mustang with a t5 and someone had used 80 90 in it and it shifted like crap i switched to redline synthetic atf and the thing was like brand new super smooth. also being that 4 hi is synchronized the lack of use and possible low fluid is most likely whats going on. supposed to be 10 to 15 below here tonight without the wind chill i feel your pain. can't wait for spring no mud everything is frozen

I checked the fluid, fluid was bone dry. I put in 2qts of ATF fluid. I can shift into each gear fine. Neutral works, 4low acts like it's working, low rpms. Can't go past 10mph, etc. but still, no 4wd.

You check your front axle disconnect?

Sounds like either a vacuum line issue to the CAD or the CAD itself. There is a vac line "plug" (so to speak) on top of the t-case you can easily see from the drivers side. Follow them all and look for cracks or leaks. Behind the front passenger tire on the axle, you'll see two vac lines that plug into the Central Axle Disconnect. I'm currently having the same problem with mine, need to get into it, like you, when the weather gets a few degrees warmer... There are several posts and threads on here regarding this issue. If the CAD is the issue, probably very simple fix. Like gunked up with crap and can be cleaned and soaked with PB Blaster, so I've read. Good luck!!
