Just wanted to say a big thanks to all bought a 2003 4.0 4X4 with 149,000 miles on it about a month ago. The truck belonged to an elderly man who has Alzheimer's and his daughter was selling it. Had been sitting for awhile. At first I thought I had gotten into a mess. But with the help from you guys I have it almost all straightened out. I replaced the plastic thermostat housing which cracked almost immediately. Then. Blend door actuator , shocks,cab stoplight leak, blown bulbs in instrument cluster, differential grease replaced,plug wires and plugs. The biggesrt difference however was learning about the slip yoke needing grease. Made ALL the difference in the world. All of these things I was able to repair myself with the help of you guys. Thanks again!!
