A coworker of mine has a 2001 TJ 90,000 miles 4.0L auto. It’s been sitting in his yard for awhile and wants to get rid of it. He said I could have it for free as long as I bring a trailer to pick it up because the frame is rotted. 4Lo doesn’t engage and 4Hi will but slips out. I’m looking for a cheaper way to get into off roading. I’m capable with a welder and working on it myself. Is it worth saving this or should I find a Jeep with a better frame and just swap the motor? It won’t be a daily driver just a weekend off-roader that I would prefer to drive to the off-roading spots.
