Rear end acted up after manuallel putting car into 4 wheel drive.

Look in the eaglepedia.

I checked the eaglepedia and only seemed to find information about the transfer case, nothing about the front axle using vac hoses.

Somewhere there is an explanation about locking in the front axle with a hose clamp.  It's a simple job but can be messy because you have to pull the cover off a small box and let the gear oil run out - sometimes down your arm.
The shift motor on the transfer case can be tied into place with wire.  I ran my 83 that way all last winter and just cut the wire and put it into 2 wheel drive in the spring.  It had jumped into false neutral the winter before and almost stranded me a few miles from home.
It does not hurt an Eagle to run in 4 wheel drive all the time.

Thanks, I will have to let my mechanic know as I believe right now he is just trying to find a way of having the switch on the motor for the front axle stay in place, though this seems easier.

what does the shift motor look like and how did you tie it in place. Sorry about all the question just want to be as detailed as possible for when I tell my mechanic.

Thanks for all the responses. Well my mechanic work on it and it seems the lever on the transfer case had simple come loose. Might still have my mechanic lock the front axle in the way you guys have shown though he seems confident in the way he did it and I do not want to offend him. Something about him working 30 years on cars and knowing what he is doing, or so my parents say.

Not discounting your mechanic's actions, there are a few ways you can lock front axle but my dad got thrown out of an auto repair shop years ago because the mechanic said, "I've been doing this 30 years!" My dad said, "Just because you've been doing something for 30 years, doesn't mean you've been doing right for 30 years."

since it failed once he sounds like a vet mechanic that needs all the help he can get.

If he is not so arrogant than he would accept it.

I do not think my mechanic would be the problem it would be my dad. He seems to think he is right about everything and hates it when people doubt his vehicle knowledge, plus my parents are helping with the repair bills.

Also just wondering but what would happen if I replaced my Transfer case with a 119 which only has 4 wheel drive? Can it be done on a 1984 Eagle.

I recently did this swap in my 1983.  you have to make sure that the front axle is locked in 4wd or the car will not move at all and just spin the front drive shaft.

You have to make sure that you get the correct speedo gear for the 119 cause it is bigger (physically) than the one in your current unit.
Your speedo will be in accurate after the swap.  mine says it's doing 20 when the car is actually going 25 and says i am going 57 when the car is actually going 65.

Could it be because the car the 119 came out of had a different axle ratio than yours?

Were did you find one. Around where I live even ones in Junk yards are a rare site. Drove 6 hours just to get mine. Do they come up for sale on this site often? Looks like I will not be able to get the Eagle back in to lock the front axle the way shown here until thanksgiving. Then again he said he has done it before and so far it is working well.

What is your reason for wanting a 119? Changing out a transfer case is a lot more work than getting the transfer case shifter mechanism working. If you really want one, I may know of one in the Denver, CO area from my old 81 Eagle that had 85k miles on it.

I would just repair the vacuum system but can't seem to find a diagram for my model year. Will have to see what the gas millage will be like but I kind of like the idea of having it in 4 wheel drive all time, plus with a 119 one less then to worry about going out of 4 wheel drive, then all I have to worry about is the front axle. I thought having the 2 wheel drive option sounded nice but is the game millage really that much worse with 4 wheel drive? I guess you could say I live the better safe then sorry motto. Worry about small things and what could happen.

The diagram I gave my buddy should still be up on http://oljeep.com The Jeep diagrams for the GW are almost identical for your setup. Jeep made it way more complicated than it needed to be. By '86 they fixed that by doing away with the vacuum front axle (like they were originally in '80/81 except 2wd was still possible)

Best setup: Vacuum from motor to reservoir. From reservoir to switch. 2 lines on switch (2wd and 4x4) Flip switch and vacuum goes to tcase vacuum motor, pulling it into 4x4. (this is with a locked or non-vacuum front diff) Flipping switch other way moves tcase vacuum motor to 2wd position. Best part? It is now shift on the fly!
