4.0 Oil Pan Removal

I need to replace my oil pan on my '03. A friend of mine who is a mechanic said after looking it up in a chilton's manual, the motor mounts need to be disconnected and the motor lifted up a few inches to allow for the right clearance. I looked under the thing, and I really don't see how theres not enough room if you take the exhaust off. If need be, could I drop the front axle a little bit to make room? that would be a LOT easier for me to do than jack the whole motor up.

The FSM says to lift the engine. All you are doing is getting enough clearance to be able to remove the pan. You could do it by lifting the engine or dropping the axle.

It is easier to just undo the four exhaust bolt from the mainifold and then you can get to all of the bolts. Remember to keep the bolts in the proper sequence as there are a few different type.

Yeah, I put my budget boost in and I have the feeling by disconnecting the sway bar and the shocks, I could drop the axle down at least a few inches to get to it. I was planning on disconnecting the exhaust at the downpipe and then sawzall-ing it off somewhere near the transmission skidplate and then just welding it back together after so its totally out of the way.

No need to loosen motor mounts, or remove the axle.
As stated above, simply remove the exhaust @ the bottom of the collector, and remove the pan.
It's usually a two-person job two slightly pry back the exhaust while the other person carefully
drops the pan.
Super simple. I've done it a number of times on my '98
And definitely keep track of which bolts go where. There's a number of smaller bolts, and (4) slightly bigger ones. Some of the smaller bolts have a longer shaft that is used to connect the transmission cooler lines.
Once you see it, it'll make sense.

Just a tip. You may allready do this. For those of you that don't... I get a peice of cardbord. Mark front on one side. As you take a bolt out punch it through the cardboard in its corisponding location to the oil pan. I found that if I get side tracked during the project or have to let it sit overnight. I have a hard time remembering where the bolts go. So this way I don't have to try to remember. Just a little tip to help out.

This can be a challenge is you have a RELA kit.
I've only been able to remove the exhaust from the collector, and that's it.
Little bit of strong-arm'n the exhaust and the pan will pop out.

To re-visit this question. I hit mine on a rock this weekend near the drain bolt, creased the metal near drain bolt and twisted it some. Not real deep dent, but something I want to replace in near future.

For a stock vehicle, removing the exhaust and possibly jacking up body (but leaving motor mounts alone), should give enough clearance between pan and front axle, correct?

What else needs to be removed back by the bell housing (manual transmission)?

I plan on replacing pan and getting the terraflex HD skid (similar to the Nth degree) - mounts to bell housing and up front to sides of motor.

i had the same thing happen, i put my jackstands next to the lca mount on the frame and took the front wheels off. the axle was at full droop and i just unbolted the exhaust at the collector. although on mine i had to disconnect the bracket on the transfer case to move the exhaust enough.

i went with the aev/nth skid and no complaints except the hardware wasnt included with my initial purchase from quadratec. a quick phone call to qtec's customer service and a hardware kit was on its way

one final bit of advice is maybe plan on doing a oil pump too, the pickup may have bent but you wont really know til you get in there

when i did mine i put jackstands on the frame and let the axle droop all the way down, unbolted the downpipe from the manifold and got the old pan off. it took a good bit of pulling on the exhaust to get it out, and it came out just barely. i couldn't see how i would get the new one in place without messing up the gasket and rtv. i ended up cutting the exhaust right by the t/c skid and the new one went on much easier without the downpipe in the way. my oil pump was fine, and i did a new rear main seal while i was in there, not because it was leaking but because i was going through all the trouble of replacing the pan anyways. i also got a pan from napa and was disappointed by the quality, and a mopar pan was only $40 more and was much nicer.
