Hi, my JX8 2000 dropped this while driving this past weekend. Looks like a sway bar u-bracket but it looks a little different than what I’ve found available online. Car’s in immaculate condition, no visible rust, with only 65K miles on it. No dash alerts and no noise when driving it. Taking it to the garage but need to get the part. Thanks for any help!

 

It appears to be a bracket for some part of the suspension that holds a rubber sound insulator in place. I would start with the sway bars, but they can be used in a few other places too.

 

Technically it is a Stabilizer Bar or Anti-roll Bar.(nothing to do with SWAY)
The bar is to control body roll along a longitudinal axis
A PANHARD ROD is a 'sway bar'.(side-to-side' motion along a lateral axis)
