dude once i was stuck in the mud with my f150 on 33" street tires. haha i done worse stuff to it than you could think of. like hammering on the gas , hitting the rev limit(a little past red line) and i still kept it to the floor for about 5 minutes. but i had vibrations(more like the front end would start bucking like a bull in a rodeo) in the front end...guess what... i power washed the ifs and ...no more vibrations. and it still drove fine. thats a ford for ya. i know its not a jeep but still.

 

that's how you get out stucky situations I do that ALL the time and my jeep is fine. Don't worry about it. It wouldn't hurt to climb under there just to make sure everything is....still there.
