I know we already have several threads discussing this very common issue and known TSB.
Figured it would have been in the DIY write-ups by now or something but I don't see it.
I have the classic thudding/leaking differential fluid on the rim issue.
I want to fix it myself but not without some detailed instructions.
Anyone know where I can find a good write-up or make one for me real quick? :)

Sounds like your axle bearings are shot.
The TSB should have detailed instructions.

" ACTION:
To service, install Rear Axle Bearing Service Kit, Part Number 3W1Z-4A109-AA. Refer to the instruction sheet included with the service kit. "
I'd like to have some instruction before I have the kit, and unless I can get a deal on the kit itself I will not be doing the entire thing, I just need to address the issue at hand or at least stop the leak for right now. I am a poor college student :/ lol

It's mostly an easy job but you will need a socket big enough to put the new bearing and seal in or a bearing/seal installer kit. You will have to remove the rear brakes. Remove the rear ABS wheel speed sensors. Remove the diff cover, and remove the differential pinnion shaft from the diff. Push both axles in one at a time and remove the c-clips. Pull the axles out. Use a slide hammer with a bearing puller attatchment to pull the bearings and seals out together. Clean out the diff and install the new bearings and seals. Then reassemble. If you have mechanical abilities and the tools its cake.

Okay this helps for the most part...I do not have a bearing kit but I am willing to pick that up. Any more detail on the process would help. If I go through with it I will make a step-by-step instructional with pictures on how to do it for the rest of the community. Personally I am a visual learner so reading things only does so much for me...I have to see it. Thank you for the input.

Chances are good that you also have at least one bad axle. Recommend you buy the axle TSB kit as it will have everything you need minus the tools. Either that or pull things apart and assess the damage then wait until you obtain the needed parts before you can reassemble. It really isn't a job you want to do twice if you need more parts. If you only need one axle, or you really luck out and don't need either, you can sell them either here or on CVN pretty easily.
Most FLAPS have some sort of loan-a-tool program for the bearing puller, installer, and the slide hammer if you don't already have them. Although the job is pretty straight-forward, I would recommend you do NOT try it without the correct tools or you may do more damage.
