You know when it all boils down to it, its all about how you drive. and what you expect. my 05 has 110k on it, I've replaced the spider gears and one seal and bearing. All of those miles were HARD. Pulling easily couple grand every other trip. I would also downshift to slow the load down cuz the brakes can't handle it. (people in houston suck) I'm talking about round bails of hay (approx 800lbs) a 16x8 lowboy flatbed. twin seadoo trailer with them, 17 ft Boston whaler, misc crap. Long story short I'm have beat the stuff out of my jeep and she is still going strong ish. as strong as she can be. I do light trails like at the deer lease and stuff. But that's rock crawling with a trailer(corn, stand, feeder, supplies). Oh Also I replaced the spider gears at like 75k. I was trying to blow the tranny because they suck and it was screwed from the factory, but new spider gears and its running again. (Jeeps don't power slide well with a lift and bigger tires. 90% of my miles are highway.
