I'm getting ready to take this 99 Limited AW4/242 from Portland, Oregon to Austin, Texas. This will be the 4th vehicle with over 200K miles that I've driven across the country.

In the last 2 months, I've gone through this Jeep and replaced/fixed a lot of things.

• All new(Up Country)shocks, leafs, coils, LCAs, track bar and sway bushings
• 235x15 Cooper AT3 tires
• Full Tune-up
• 4 Hole 784 Injectors
• All new exhaust including Manifold, o2 sensors and muffler
• New U-Joints up front with new Timken Wheel Bearings.
• Valve Cover, Distributor, Rear Main, Oil Filter Adapter and oil pan gasket
• Cooling system flushed + New Thermostat. I didn't replace water pump because I am lazy.
• Brake flush, transfer case fluid change and power steering fluid change

I thought about installing a trans cooler, but mine came with the external one and I don't feel like replacing it since it's not leaking

I plan to carry coolant, oil, trans fluid, brake cleaner and a big tool bag of all common Jeep tools. I'm also carrying a lower radiator hose, water pump, thermostat and a tire patch kit.

If anyone has other suggestions for what to bring specifically for the Jeep, please let me know. I'm hoping to get 17MPG highway at minimum

 

I’m gearing up for something similar. 1500 miles to Moab, 1500 home on a 250k machine. Your list looks solid and similar to where I am. I think you’ll make it just fine.
