Oil Pan Leak

I noticed something leaking from under my 09 WK, took it to a mechanic and we could see the oil pan has rusted and the oil is seaping through. Anyone else have their oil pan go bad? We looked up on how to remove it and it calls for 4-6 hours. You need to take off the intake manifold and everything on top of the motor in order to raise the whole motor to have clearance underneath to get the oil pan out because of a cross member and the front axle being in the way. Has anyone been able to get that oil pan out without jacking up the motor?

2009 Engine, 4.7L / Lubrication / PAN, Oil/Removal

You didn't specify an engine so I chose directions for the 4.7. (You still have to raise the engine some, and take off the axle.) This is from the service manual.

09 - Engine, 4.7L / Lubrication / PAN, Oil/Removal
REMOVAL

Special Tools:
8534B - Fixture, Driveline Support

SEE FIRST PICTURE
1. Disconnect the negative battery cable.
2. Install engine support fixture (1) special tool 8534B . Do not raise engine at this time.

SEE SECOND PICTURE
3. Loosen both left and right side engine mount through bolts (3). Do not remove bolts.

SEE THIRD PICTURE
4. Remove the structural dust cover.
5. Drain engine oil.

SEE FOURTH PICTURE
CAUTION: Only raise the engine enough to provide clearance for oil pan removal. Check for proper clearance at fan shroud to fan and cowl to intake manifold.

6. Raise engine using special tool (1) 8534B to provide clearance to remove oil pan.

SEE FIFTH PICTURE
7. Remove the front axle.
NOTE: Do not pry on oil pan or oil pan gasket. Gasket is integral to engine windage tray and does not come out with oil pan.
8. Remove the oil pan mounting bolts and oil pan.
9. Unbolt oil pump pickup tube and remove tube.
10. Inspect the integral windage tray and gasket and replace as needed.

you say 2009 3.6l, I assume you mean 3.7l

Is this the same process on a 2005 3.7 all time 4 wheel drive?

I service manual states that it should be the same, with no disassembly of the front suspension, but I have seen online where people state that it is wrong and you must drop the suspension on this model.

Can you verify that?
