Here we go again, Getting ready to start my next project
I will post a follow up video in the next few minutes (once youtube finishes uploading) with the jeep up on jacks (cinderblocks because someone stole my jacks ) and its funny, the jeep seems to sound fine when its running and even if i give it a little gas. but as soon as i hit the brakes it starts jumping, however as you can see in the first video this is not the case when i am driving normally.
Sounds like shocks or maybe Track bar

What was the diff. oil like when you pulled the cover? If the diff. is the problem the oil should have had at least very fine metal fillings in it making the oil sparkle or it could have chunks of metal in it. My guess is that you either have a trashed diff. (spider gears) or possibly a broken axle shaft. The reason that applying the brakes makes the noise could be because one brake either left or right will contact first or harder than the other making the spider gears turn as if you are cornering slightly. I don't know if you understand how a diff. works, but my bet is the diff. is bad, but that is major work so be sure to check everything else that is easy to fix first.

I took it to the jeep dealership around my way yesterday, I was going to try to do it all myself but I don't have the time to work on it, thanks for all the help and I'll let you guys know everything that happened.
When my rear went, it made a buzzing/rubbing sound like loud tires (too bad I thought it was my tires so I disregarded it for months), and when it finally went it was LOUD, I barely made it 10 blocks home. I mean embarrasing loud, like you'd go to the window too see what the racket was. That last block I had to run in 4wd to make it, the rear was completely gone.

You should have just pulled the cover to begin with. You didnt know the last time the fluid was changed so should change it anyways. You could have checked the diff and did maintenance at the same time
Hey what ended up being the issue? My 02 has started making the exact same sound. I have replaced sway bar links and bushings, lower control arms and bushings, rear shocks and rear drive shaft u-joints. Mine isn't as loud as yours but still the same sound. Before I take it somewhere I want an idea if it is something that I can do.
