Noise from driver side when brake is applied?

[msdz]

I checked the fluid but have not added any to it. Still the same fluid as when I bought it. When I checked the frotn I just had a little tiny bit touching my little finger and thought it was good enough and left it alone. I was looking at buying a new bearing kit and thought that was when I would go ahead and put the correct fluids back in.
I am just wondering though, if I replace the bearings in the differential has the grinding I been hearing caused damage to the transfer case since the 4WD switch is showing up as bad in the VIC? I imagine it goes in the transfer case. I can't find anything on where it is located at.

OK, as far as fluid I have not put any in yet. The differential looked good when I had checked it so never added any.
Seems like I am starting to have all kinds of bad luck with this Jeep all at once after a year of having it. In that year the only problem I had that I knew about when I bought the Jeep was the VIC showing the RLF and I tried chasing that problem down with no successs but anyway the transmission started slipping on me today. Checked the fluid in it and it was only half a quart low, that should not have been enough to make a tranny slip!! Never rebuilt a tranny before and I am not spending $1,000 or more on a rebuilt one or getting it rebuilt. It will go to a crusher first. I wouldn't even give it to somebody with all the crap happening to it now. Tranny, noise from the front end area, what can be happening to this Jeep??? Oh, the fluid that is in the tranny looked and smelled really good, no burnt smell or brown coloration at all.
I feel like if it wasn't for bad luck I would have no luck at all right now when it is coming to my vehicles. Never had a good vehicle since I got rid of my Chevy truck. I WANT IT BACK NOW, lol.

OK, after doing much searching and reading on the internet I came across a few articles that described my problem to a "T". It is apparently the viscous coupler that has gone bad in the transfer case and the whole transfer case would need replacing. This can also have effects on the transmission cause it makes it harder for the tranny and even the engine(gas consumption) for it makes the front end harder to push. Or at least this is what I had read and seems like it makes sense to me the way the person described it.
So, I guess I will be trying to get rid of the Jeep or maybe check to see how much a rebuild kit is. I have rebuilt transfer cases in the past on older model vehicles but I really have no idea if this would be about the same or not. I may try rebuilding and then get rid of it if I fail to do a good job, I am sure I can find some poor sap to buy/trade for it, lol.
Any hints or web site links that may help me research rebuilding of the transfer case before I get into deep?
