 I bought this 4 door 4.0L 4x4 with 105k miles 3 years ago. After 170k I have had to replace the O2 sensors, alternator, steering column wiring, AC/Heat controls, power window switch, transfer case motor. The automatic hubs went out around 150k. The truck has never held an alignment. I have pulled more than 5,000 lbs with it and have put it through three years of heavy off road and on road abuse. It has been more reliable than I could have ever hoped it would be, I just wish I would have sold it at 150k. The rear doors are great for throwing small things in the back but the rear seats are not suitable for anyone over 8 years old. I would definitely buy another.
