There comes a time in every Jeep life, when a u joint goes. In this case, mine was on my upper steering shaft. In Jeep engineer wisdom, the joint is not a serviceable/replaceable part. I had to replace the entire shaft. That in itself proved to be a difficult pIart to find. I was finally able to source it via Amazon.ca in the form of a Crown Automotive 5102531AA Steering Shaft. It's a simple two bolt process to replace it, and aside from bending in ways that I didn't think my body could bend, and a buggered thread that needed tapping, it was an easy swap
|Engine compartment bolt|
|Potato quality short under the dash|
Slide the shaft off in the engine compartment, and off the splined shaft under the dash. Pull the shaft into the cab and it'll pop through easily.
|Old vs New shaft|
Get your new shaft, repeat the process and tighten your bolts down. Just remember, when the shaft is disconnected, do not let the steering wheel spin, as you'll break your clock spring and mess up signals and air bag. I used a bungee cord to hold the wheel from turning.
