Ha, has anyone replaced a oil pan?!?!? are you serious man?

it should take 30-45 minutes if you haven't done it before. Go to wholesalemopar.com for oem stuff, 4wd.com for aftermarket/oem stuff. They both have decent prices.

Go buy a Haynes manual, it will save you a lot of time and you will learn quite a bit.

Parts books suck for newer Jeeps. I had to replace the pan on my '03 and couldn't find one that said it would fit. So, I asked a guy at the dealer parts counter to run some numbers for me and found out that they are the same at least back to 2001 (maybe older).

Replacing the pan is simple, but becomes a PITA because of the exhaust manifold bolts that will be pretty frozen in place. Don't follow the directions in the FSM as they add a ton of steps that are unnecessary.

Unbolt the exhaust from the manifold. Then unbolt it from anywhere you can under the Jeep so you can drop it out of the way.

Then just unbolt the old pan, making sure to keep the bolts in order. Just make sure you drain the oil before you do this or you will be looking at a big mess.

Then just bolt up the new pan and gasket using a dab of silicone in all four corners. I have no clue what the torque specs are for it, but mine works fine just taking the bolts a little past snug.

Reconnect the exhaust, fill the oil, and check for leaks.

Mine took me all day, mostly due to the exhaust manifold bolts and the amount I had been drinking.

the above is a pretty good summary :D
On mine the exhaust caused the least problems, but getting one of those darn bolts in on the backside of the pan ... now that was a major PITA and working upside down sucks ass too and bending the little siderail on the pan also helps in being able to get a ratchet on the bolts.
Make sure you apply that silicone on the gasket where it makes the roundings (on both sides and top and bottom) to avoid leakage :)
