Depends on what kind of work you are mentally prepared to do on the trail. I carry front wheel bearings and inner seal, locking hub assembly, whether manual or auto. 1 quart/liter of gear oil for diffs. Not a full volume. Just some to help make up for partial loss. I would recommend a rear wheel seal. Rear wheel Bearing might be a good idea, but that's a bit challenging to replace on the trail. One or more u-joints of each size needed. Brake hoses could be a good idea and/or something to pinch off a broken hose. Brake fluid for brakes and clutch. ATF - used in transmission, transfer case and power steering. Engine oil. Coolant. Fuses, extra relay, wire, crimp connectors, hose clamps, zip ties, bailing wire, short length of 1/4" rubber hose. At least one good spark plug. Bucket to catch fluids, funnel to replace fluids, all tools needed for any of the parts you carry. Cribbing to put under jack for stabilization or to add height. Shovel, recovery gear - ropes, tree savers, straps, shackles. Ratchet straps. Pruning saw. Matches. Good first aid kit that has serious stuff in it, not just band aids and burn cream.
Or, take your chances and just wing it with a pair of flipflops and pack of crackers. It's your choice.
