Christiaan, if it's rattling around maybe the bushings are worn out that are on the existing contact points/brackets. I can't exactly remember from the last trip in the Mojave when your shock folded if the front sway bar was connected or not but that's the first culprit I might look for. If it's disconnected and you are getting noise I wouldn't be too concerned about it unless it's able to work itself out and into something that might cause you some issues.
It's definitely not connected right now; you can see it's just chilling in mid air like " I'm pretty sure I'm supposed to be doing something...but, I'm not, so I'm gonna just chill right here"
Not overly worried about the rattle; it drove me nuts for a few months, but it's just a sound, goes away once I get her up to decent speed, and doesn't affect really anything else...cosmetic more than anything else
