4wd not working

[Grizzdog]

So I guess I have the worst luck, My trip to texas was a blast but I found out what they called "Gumbo Mud" is.

After we had the 6 inches of rain i couldnt move anywhere and found out my 4wd isn't working.

Where do you start to figure out whats not working?

Turn the switch and the light comes on instantly.

My HVAC controlls all work so im assuming my vacuum is fine.

I didnt see any lines disconnected to the front hubs, and they both lock and unlock by hand.

I would check the solonoid on the t-case have some one get down their and listen to see if you can hear it engage.

Conections are fine. ive got a vacuum leak somewhere that i cant figure out. If ive got the vents on the floor and turn 4wd on it goes to defrost. i changed the lines in the wheel wells and it still doesnt work. ky one hub is hard to turn going to try servicing that next i guess.

I can hear the t-case shifting in and out.

If the vacuum has a leak, cant you still manually lock in the hubs and still have 4wd? I tried to put both in manual and still no 4wd.

Hubs shot is what im assuming.
