If you still have the OE steering linkage you might want to bring a spare idler arm and tie rods. If you have an idler arm brace from one of the after market outfits then you can probably do without the spare idler arm. I've seen both these items break or bend on the trail and it's no fun if you don't have a spare. Also, though I've never seen it happen, some folks break their auto locking hubs.
