I have been working with Jeep Cherokees ever since I bought my first Jeep Cherokee XJ in 1986. It was a two-door with a 2.5L four-cylinder engine. I later upgraded to a 1990 Four-Door with the Renix 4.0 engine. I then traded that for the 1991 shown above. I have been driving that one ever since. The odometer stopped working at 444,444 miles. I have lost track of the actual mileage on this XJ due to having to swap the cluster a couple of times to get one that worked reliably.
I also built a Jeep Cherokee Rally Racer and raced in SCCA and NASA performance rallies. I later converted this Jeep to an off-road rock crawler.
Both of my sons drive Jeep XJs and my Dad has an XJ Wagoneer that we have restored and added a 4.7 stroker motor to. So we are an XJ family. I have also been helping other friends service theirs for years.
I hope I can share some of the things I have learned in a way that will help you keep your Jeep XJ running well for you.
I also have a few other hobbies such as low-budget endurance racing a Porsche 944 and mini bikes and go-carts. I will share these as well because sometimes the lessons learned overlap.
