Dana 30 Axle Seal Replacement Advice

Hey guys, my driver side axle has been leaking fluid into the knuckle, so I figured my axle seals where going bad. I called the shop and was quoted 500+ to change the seals, so I decided that I am probably capable enough to do this all myself, and should have every tool I need anyways.

I have never been in a differential before, so I was wondering if anyone would have any advice going into this process.

I have a Danna 30 front, with an ARB installed, 4.56 gears.
Its a 99 TJ, and Im not sure what axles are in it, Im going to call the shop that originally did the work to see if they can help me out, (the truck was set up when I bought it.)

Am I correct in saying that the type of axle seal needed is specific to what kind of axle is in there?

and my last question is what should I use to reseal the differential when Im all done, a gasket, or some sort of calking?

thank you all so much for any help, tips, recommendations or advice.

The seal will be the stock one no matter what axles are in there. I use Silicone gasket maker for the diff cover. To install the new seal use a socket that fits into the seal and a couple of long extensions to drive it in from the opposite side the seal is going into. Notice the way the seal comes out and install it the same way. Do both while you are in there. Cost the sealing surface with grease after installing the seal so when the axle goes in it slides over the seal and does not damage it.

Here is an example of a walk through: http://jeep-xj.info/HowtoD30AxlesSeals.htm. Seal shouldn't matter whether different axle shafts or not. RTV works fine to seal the diff back up, although Lube Locker gaskets are nice and save the mess.
