Best way to remove 4.0L oil pan?

I have a small leak from my oil pan so I'm thinking about changing the gasket. Is the FSM procedure (below) the only way to go, or is there a better way?

I'm not sure, but I would like to know, for the near future.
I have heard it both ways, you need to take off exhaust, and you don't, so which is it ?

i was able to do mine by just jacking up the motor from the transmission and slipping the oil pan out that way. i didnt have to remove the exhaust. i did have my starter out though.

Be careful jacking on the damper pulley. Most are rubber mounted.

if you get to yours first let me know, im hopefully pulling mine son for a leaky front main and replacing front and rear and checking out the bottom end and im the type of person that will drain the oil then unbolt the pan and see what it hits.

Exact same FSM oil pan removal directions as the 96. Not sure if it was easier but I dropped the axle down instead of jacking up the engine. Didn't like the idea of maybe damaging the seal on the damper pulley and seemed like too many close things on the top rear of the engine/trans near the firewall.

Probably a whole lot more info in this thread than you want to read. Huh, HD?

The short version for dropping the axle is you undo the tops the shocks and take the axle end track bar bolt out. I only unbolted the sway bar links since they seemed to be on a bind. And since you're pulling the pan back towards the drivers side the exhaust shouldn't have to come off if you can get to the pan bolts.

That sounds like a better way, I don't like the idea of jacking the engine up on the crankshaft pulley. Hopefully I'm getting the Ingersoll Rand W7150 for Christmas, which will help me break that track bar bolt loose - couldn't manage it even with a long cheater pipe when I did my coil spring isolators earlier this year.

I had to drop the exhaust on my 5.2 and was still a pain to get the pan out. The 4.0 I did, did not need the exhaust removed. Both kinda a pita but definately manageable.

4.0 was easy, I just jacked the body straight up, and pulled the pan out. No problem. No disconnecting shocks, or the trackbar, etc... Now on the V8s it's a different story.
