Sorry for the luck Jeeps. I am betting it will be alright. Jeeps can take alot of abuse. Drain the diffs as suggested by another. Don't forget the axle vents when you do the snorkel install. This is also a good excuse to apply a bedliner (Herculiner) to the inside of the Jeep. The carpet and seats will probably be a little bit funky.
Next add should be a locker and a winch.
