holy crap, what don't I bring. oh wait, that's right, a water pump. :shake: The one thing that truly let me down. At least it was on the way home from the 3 week trip.
I generally bring everything I can think of. U-joints, pair of axle shafts for the front, one for the rear, spare hub, tie-rod, various light bulbs, fuses and engine sensors, lug nuts, wire/hose, nuts/bolts/screws, engine belt, 3 gal of drinkable water, full oil change, alternator, and I'm sure I'm missing stuff. Yeah, I'm that guy. :D If it fits, it goes with me.
But since I have Ford axles and a lot of custom parts, I also bring spares for Jeeps too. tie rod, front axle shafts, unit bearing, Dana 35 C-clip rear axle shafts, HO sensors, etc. Just stuff I had left over. But I don't necessarily carry all that heavy stuff with me on the trail. I'll leave it behind at camp.
