I've been thinking about what the minimum is that I need to put together for trail spares. So far I'm thinking.... 1. Fluids. One bottle of brake fluid and ps fluid, two or three quarts of gear oil, motor oil. 2. Assortment of wiring, connectors, zip ties, fuses, etc. 3. Assortment of tools. Only carry sizes that are on the truck. 4. Front axle shafts 5. Extra set of locking hubs 6. U-joints and/or D-shafts 7. Wheel bearings 8. Pair of brake calipers. Same front and rear, so I'd be covered either way. 9. Rear axle shafts. I don't how often guys break 14ff axles but.... 10. Tie rod ends I could go more with say an extra alternator, starter if I was auto, etc. Stuff like the tie rod ends are $ to just carry around. Stuff like calipers starts to take up space and add weight. At what point is it too much? This is stuff that I plan on having in the truck at all times, not just when on the trail, and I'm going to incorporate it all into the truck somehow so that it takes up the least amount of space as possible. This is on my rig in my sig. Anything I'm not thinking of or can do without? I don't plan on rebuilding my truck on the side of the trail, but want to have what I would need in most cases.
