PLEASE HELP! Simple LCA question

[TommySmalls]

Hi all,
I'm inheriting an Expedition through my fiancé, and I went to swap out the rear shocks today as they were in bad shape, and I've come across a possible issue. When putting it all back together, the nut that goes on the bottom/outside LCA bolt wasn't going on, and I noticed the entire bolt was spinning. Did a bunch of internet searching and can't figure it out. I removed the LCA and took a quick video of it and put it on Vimeo here:
Can ya'll please tell me if this is normal? Or if I need a new LCA?
With the way the bottom of the bolt is a hex shape, I'm wondering if that's where I'm supposed to hold it still while I crank the nut up? The drivers side went smoothly and I didn't need to do this, but with the rubber boot around the bolt I'm wondering if this is just fine and by design. we're going on a long road trip starting tomorrow and I want to make sure we're safe.

THANK YOU so much in advance.
-Tommy

That's the lower ball joint. You gotta force it down into the taper that it goes into until you get the nut tight.

Oh good! Thanks for the info that was what I was hoping. MUCH appreciated!
How do you force it down?

Figured it out with a long screwdriver under a bolt head. Thanks again. she's ready to drive now
