Hey all, I had some questions about replacing the oil pan (which is rusted through) on my 2005 Grand Cherokee 3.7L.
I see most people lift the engine, but has anyone tried removal of the front diff assembly to drop the pan? I do have access to a lift and air tools, so that seems like an easier option for me.
Also, does the sump tube come out with the pan?
Any input or advice would be greatly appreciated. Thanks!

Drop the axle. Much less work to do that than lifting the engine which at least one member here found was in sufficient to get the pan off of his 4.7.

If you're lucky, you might not even need to disconnect the CV shafts to gain enough room for the pan.

A word to the wise though, get a new bushing for the diff mount above the pinion. They go bad often and will cause noise and premature wear on the front driveshaft.

I did the oil pan on a '07 wk with a 4.7. a couple of weeks ago. I did it on the ground, so completely removing the front diff, gave me some extra room to work. If you're doing it on a lift, maybe just lowering the diff will give you enough room. Didn't have to raise the engine. Not sure how similar the 3.7 and 4.7 are. but when pulling the pan, the gasket is part of the windage tray, and stays with the engine, when you remove the oil pan. Then there are some bolts to remove the windage tray(and gasket) and oil pick up tube. Pan was VERY stuck to gasket, needed a wide flat pry bar, started in one place and worked around pan. Also on mine there was support bracket between engine and trans. unbolted it but not enough room to remove it, but you can move it back and forth and work around it to get rear pan bolts. So get a new oil pan gasket and "O" ring for oil pick up tube. Good Luck!

Just finished her up about an hour ago; Not as bad as I thought it would be. I ended up dropping the front diff down and let it hang with the axles still attached, then I removed the RF engine mount bolt and jacked the right side of the engine up so I could remove that pesky plate that bolts to the trans at the back of the pan.
The hardest part was separating the pan from the gasket of all things. Luckily all the mount bolts came out without issue and everything went back together clean.
Not a bad job, would I want to do it again...No. Haha.
Thanks for all the input!

If your putting a new oil pan and gasket on,than all you have to do is take a dremel with metal cutter and cut a 2x2inch square towards back(big belly part w/plug) than cut another 2 by 1inch give or take towards front of oil pan (carefully, very carefully) and than when your done you will see the bolts holding the oil return pipe (13mm), undo those 13mm bolts and the pan and all should drop down if you stick your hand in the first box you cut and wiggle on the return pipe, than bring the pan towards the back and down while turning it counter clockwise and out and it should be free so you can reinstall everything. You will see what im talking about when you do it.. but you definitely dont need to drop any differential or axles or anything, just undo the 10mm oil pan bolts and make the cuts undo those bolts and your good to go. Be more complicated if you may but this is how we did it in my 2008 jeep grand Cherokee laredo 3.7

Hello,,I’m in the midst of doing mine. I have the 2008 3.7 Laredo.? I noticed the pick up tube is in the way of me shimmying out the oil pan on an angle. I will be cutting holes to access pick up tube bolt also. My question is, after reassembling the pick up tube; does the new oil pan go on easily and did you have to use gasket sealant or just torque to specification ? I’m a 54’ retired nurse learning to repair my own car 😂🤷🏾‍♀️. Please and thank you.
