Steering Shaft - Up/Down

[JKBowman]

Here's a pic of my steering shaft passing through the firewall.


Here's a quick video of what I found today.

There is nothing noticeable about this up and down movement from the steering wheel. I don't have a rattle or shake. Potholes, annoying as they are, don't produce anything unusual. Also, the steering column is solid as can be moving left to right.

My plan is to drop her off at a shop tomorrow. I'm on my way home to Florida now. Dropping her off and making it home will mean about 600 more miles and I feel safe with that, but I thought I'd ask here first.

What ya think? Entire assembly or could it be that all I need is a new boot?
