Yeah, the directions in the 96 FSM sure make removing the oil pan on the 5.2 seem easy. I noticed they said you have to "remove the exhaust pipe", rather than saying disconnect it, but not sure if that's necessary if you can get it out of the way.
Heck, on the 4.0 oil pan removal instructions they say you need to remove the engine flywheel, remove the transmission toque converter housing cover, remove the engine mount through bolts, disconnect the exhaust pipe, and jack the engine up on the vibration damper. I didn't do any of that and since had the pan stuck had to drop the whole front axle down. Did this by unbolting the shock tops, sway bar link bottoms, and finally the axle track bar bolt. I had trouble getting the track bar bolt out/in only because I didn't know the trick. Once the axle was dropped I had enough room to get the pan out/back in.
You may not need to do all of what I had to and best to let someone who has taken the pan out on the 5.2 around your year to explain the easy way, if there is one. Good luck.
