03 Liberty Oil Pan Removal Procedure

Hello all, this is my first posting...and thanks in advance for any assistance you can provide. I bought my 03 Liberty at an auction last year and it recently started leaking oil from the oil pan which has rusted out badly - layers of the metal are flaking off. The maintenance manual says to remove the engine in order to remove the oil pan. Is there a "less involved" procedure to remove/replace the oil pan without having to remove the engine?

If so, please share the procedure and advise of any precautions / safety steps I should use...thanks.
