Just bought my first 5.9, busted rear axle?

So, just bought my first niner last week with just a little over 100.000 miles on it, in nice overall condition, but with a few worn out parts.

First off all, the niner was born with the lsd right?

From what i can see on the buildsheet it has it. Now the problem is, it sounds like on of the bearings are blown somewhere in the rear axle, so i ordered a master overhaul bearing kit, but which bearing is the most likely to have worn out?

Also, when i turn slowly the whole driveline slowly locks up, when i don't apply gas. Is that the VC that needs to be replaced or could it also be the lsd in the rear?

Here's the buildsheet:

From what I know all niners had lsd's

Common problem with the rear ends is the pinion bearing going, which will require a full rebuild (well, not technically, but if your tearing it apart it'd be stupid to reuse the old ring and pinion with that many miles on it, plus new are only like $150)

And it sounds like the vc in the transfer case to me

Ok, could you advice me what exactly would be good to replace in one rebuilt?

Maybe the parts needed to fix the most common problem of the rear axle with help from the parts list?

As I wrote, I've just ordered a master overhaul bearing kit from crown automotive, but it sounds like that there is more to a complete fix, than just the bearings for the rear axle??

A working viscous coupler will naturally slow the Jeep down when you turn the wheel far.. Thats just the nature of the fulltime 4WD. If the front end starts to hop or skip tho when you turn in the front then the viscous coupler i bad.

My viscous coupler is brand new and when i turn the wheel far and say back up outa a parking spot if im not on the gas the Jeep will not move. Our 4.0 in 2WD will move effortlessly tho. This doesnt mean the vc is bad, its just the viscous coupler working as intended, its just the hoping/jumping in the front you need to watch out for.. that can wear your tires out quickly.

a complete rebuild would be

axle bearings and seals, carrier and pinion bearings and seals, R/P, and spider/side gears...possibly axle shafts, and you should at least truss the D44 from what I read

edit:
oh yea, and the rebuild kit for the LSD too
