I'm planning on changing out my rear shocks and when I crawled under the truck to see what was involved it seemed like the rear tire may have to be removed in order to get the sockets on the bolts. I've never had a flat on this truck, so I've never even had the spare tire off or even lowered. Can I do the shocks without removing the tire, and if not, can I just lower it? Come to think of it, I might replace the front shocks one day to. What's involved in changing the front? It' almost looks like the batteries will have to come out.
