Yes, I had it happen on a 2002 Wrangler. I had four new tires installed for the trip. The steering wheel locked up in Canada and scrubbed the tread off of the front right tire after they didn't straighten out. Since the other three tires were still new I wanted to find another. They were BF Goodrich 10X15 All Terrains that were hard to find until I got to Kelowna in southern Canada. Everyone was willing to order them, but I didn't have a week to wait for one.
The locking pin can be pulled out of the steering column. You need a "security" Torex bit that has a hole drilled in the middle of it. You can go to HD and buy a set of them. On You Tube you'll find videos on how to remover the pin. I didn't find a video exactly for a Jeep, but other videos were close enough.
I found that if you wrap something white around the top of the steering wheel when it's straight (the tires are pointed straight ahead) you can see it in your rear camera. Watch the white spot and make sure it comes back to the top after going around a sharp corner. I found that white "sheet" off of a lint roller worked well as it stayed in place and could be removed easily.
