Trail spares?
 

We'll be relocating permanently to N AZ soon and doing more trail driving so I'm assembling a kit of H3 vital parts that fail most commonly on the trail. So far I only can come up with is a serp belt, tie rod ends and a half shaft (both sides same?). Suggestions for other items based on real life breakdowns would be appreciated.

Depending on how hard or far out you wheel I might add a steering rack.

You are going to love northern Arizona, especially Sedona.

PS- The best spare is going with a second H3. We used to go into some really wild , remote places my ourselves but will not do that again.

Left & right are the same.

Assuming you already have UCP, I would have some fluids along. I put mine in the back door under/behind the jack.
