The howling noise wasn't there when you test drove it prior to purchase?
I would not go with those axles unless I am actually putting my hands on them to verify r/p condition and ratio, plus if they are similarly shot! The front is a 95% bolt in. Control arm bolts are smaller, which are not really an issue until you try to take yours out. Typically you have to cut them off b/c of being seized. 00-01 control arm bolts are larger. Brakes should plug right in even though yours are double piston and those older ones are single.
I concur that there is a higher probability that the issue is the LSD. These Chrysler 9.25s didn't really have any pinion issue, at least not that I have seen as common. Other new axles do. As far as I know, the Chrysler 9.25 is not by AAM. 03+ get AAM axles.
Here are pictures of my LSD showing worn clutch plates and the retainer clips that broke. Rebuilt by the dealership for < $700 Spring 2009.
The howling could also be a bearing rolling over a pit(s) in a race. Also high probability.
Go on your current path with your friend to pull the cover and inspect.

The main one I am worried about is the howling noises the rear end is making. So with research and the mechanic I had take a look at it , im assuming it is the pinion gear issue i have been reading up so much on. Seems to be pretty common with these trucks. I called the dealer to see how much it would cost to just look at the truck they said $140, then i just mentioned the word pinion gear they said ohh your looking at around $1800-1900 right off the bat!!!!!!! That was kind of discouraging and not the answer i was looking for so needless to say i am trying to find another route.
Anyways enough back story , what do i do? Find a used complete axle assembly, do i just need a new rear diff, take it to a mechanic shop?
Or buy everything i need myself and have my mechanic friend and I fix it.
Right now i dont even want to drive it until its fixed. All help is appreciated :/
Update: Here is another option as they are close to where i live would this be possible and would they fit right in just unbolt the old ones and put these right in? http://www.ebay.com/itm/261318975029...84.m1423.l2649

I just got done rebuilding my 9.25 trac lok rear axle. If your trac lok blew a dealer will tell you that you need a whole new assembly which is around $800 or so plus $400-$500 for a ring and pinion plus another $200 for bearings, and around $600-$800 for labor so yea...not cheap.
I got lucky with my rear axle, my ring and pinion were good so I replaced my trac lok clutchs, all the bearings, and some random parts for $200 no labor. An aftermarket ring and pinion shop will probably rebuild the trac lok if yours exploded. Either way your looking to spend over $1000
A way to check if your limited slip is broken in the second gen truck is to put the trans in neutral, lift up the rear axle, turn one tire, if the other tire spins the same way your trac lok is most likely good. If your tire turns the opposite way then the trac lok is broken.
I'm about 99% sure that all off road second gen ram's came with a limited slip...I could be wrong though.
