Front one usually can be done by itself because it takes more abuse, you know, with the turning and all. Really doesn't need to be done unless you are having problems with it.
Also, i haven't only replaced my water pump and radiator... Those are things i had to replace. I've done coil, cap, rotor, wires, cat, muffler, plugs, seals, oxy sensors, hitch lifts, seat frame, armrest, speakers, pass window and reg, windshield, a/c everything, t/c, trans filter, door latch, and im sure i dont need to talk about scheduled stuff. Holy f, never really listed it all, who keeps a car that needs all this work??? Someone that wouldn't let you tare his Jeep out of his cold dead fingers.
