So I'm leaving in august to go away to Penn College of Technology for the diesel program. Any I have a 2000 cherokee with 159,000 miles on it. This week im rebuilding the front diff (pinion bearing went) and adding a trans cooler, and doing my 4.5 in rough country lift. I was wondering what I should do to the jeep before I go away so I don't run into problems since I wont be working in a shop to fix them anymore. I plan on doing all my fluids (tranny diff etc), sparkplugs again, clean the k&n, new belt, and a coolant flush. Any other suggestions? I have already done my water pump, thermostat, radiator, upper coolant hose, cam sensor, crank sensor, throttle position sensor, and coilpacks (all parts that went bad). So i just want to know if there's more common problems that I may run into and take care of before I go.
