ok, you didnt hear this from me. you wont get warranty, but, for all you JK owners. keep an eye on your front axle u joints. we've had 2 in our shop allreayd where the front axle u-joint cap has come right out without warning. whe nthis happens it kinda tears the shaft apart and then it goes downhill from there. the first one we saw was in for an oil change, and we noticed a ujoint cap missing. thought it was weird. we changed the ujoint and all was well. second was much worse. they were driving down the highway when they switched to 4wd and heard a bang about 20 minutes later. the shaft came right apart and needed some serious work. we did warranty it for them as they were just driving along and they are good customers. we also noticed that they both had a lot of up-and-down play in the ball joints, but, apparently they were in spec. changed em anyways, warranty work is better then no work i say.
so, keep an eye on these things. both jeeps i saw with this problem were un-modified stockers.
