if you shift the t case in neutral it will isolate the rear from the trans. if it still does it then i would think its in the rear or a bearing

Alright, i did what you guys recommended (again) by trying to put the transfer case into neutral while moving, stopping, slow roll, etc.. and nothing except for more noise. It seemed that every time i tried to put it in neutral, it would amplify the sound even more.. i have no clue where to go from here.

my thinking would be either rear or t case. if you can hook the front shaft up and remove the rear and try it again and see what it does.

Have you check / inspected the fluid in all the drive train?
I would check for correct level. (Top off any that are low with the correct oil). Then get some of the oil between your fingers, see if there is metal shavings, or if it looks like metallic paint.
If you find metal you can isolate the component thats having the issue.
I would also inspect the front axle joints for dryness, or binding.

Ok, Ill do that this week. Probably tues since im working all weekend. But I don't think ill be able to test it that way because when I went to go get the rear end and front end diagnosed the lead mechanic told me that when the front end was rebuilt whoever did it didn't assemble the locker correctly which is why it grinds to a stop after a few feet. smh..this truck is turning into a bunch of hiccups..i paid a decent amount getting the front end rebuilt by a 'reputable' mechanic in clovis, nm.

Tuesday after I attempt to follow the directions from Irish_Alley i'm going to be changing the rear gear oil. Hopefully I do find something so I can fix something!! So far I cant find anything to fix but things are broken.

My wife is already pissed (I know, welcome to the club right?) With my newborn son my wife gave me the ultimatum to sell the truck because I have too many projects..so I just need to get it close to perfect, or at least know everything that needs fixin so I can price it fairly, and the new owner will be confident with the purchase. But If I get everything tip top hopefully she'll just let me keep it.

luckly my wife understands i need something to keep me happy besides the family. i love our trucks and she is getting to like the crew cab cause of the space it has and being able to fit the family in one vehicle and still have room for other stuff. but i have a 79 k20, 84 k30, 86 k20, 91 v3500 and a 94 c1500 (her first vehicle) along with my 04 impala ss. only one of my fleet can't see the road but she doesnt mind cause if she ever looses me she knows ill be somewhere working on one of my trucks. and it will give me and my kids something to work on. the only part she doesnt understand is why the 91 has to have a cummins in it lol

You might have your pinion set a little bit too deep.......

Thats what i was thinking and have no clue how to fix it.  But is that whats causing all of my other issues? When draining the oil i didnt find any chunks of metal, only shavings.

Uh that is definitely what is causing your noise if it never goes away until you stop...
You can't "fix" that.  I would replace that gearset and diff, or get a new rearend with gears that match your front axle.

I went and got the tranny, front/rear end and transfer case checked out at aamco transmissions. The mechanic told me:
1. The entire rear end needs to be rebuilt because of the misplaced pinion causing a lot of damage.
2. They found metal in the tcase and someone put gear oil in the tcase and transmission instead of transmission fluid.
3. The chain is slipping inside of the tcase which may causing the "pop" when I stop and not allowing me to put it in 4H or N when slowly moving
4. So far nothing is wrong with the front except for a leaking diff cover/pinion seal.
