[JackG]

Count me in as well, it's on the driver's side, behind my left shoulder, but it's hard to tell how far up/down. I had my alignment guy look at it, and he couldn't find anything.

It will pop when it's being jacked up off the ground, and will pop either when it's let back down, or when you sit in it after it's back off the jack. When driving, it will occasionally pop when cornering hard right (and loading up the suspension on that side), and will especially do it if there's a bump in the corner that loads and unloads the suspension.

My noise sounds like someone lightly tapped a solid part of the frame/suspension with a ball pein hammer. Like maybe a bolt is loose, and whatever it's holding can slide around under it's head? But the weight of the car normally keeps it from sliding.

A bad strut (shock) is a good idea. I've looked over the bottom, I'll have to take a closer look at the top of the strut and it's mounting area. I guess it could be internal as well. It's not leaking on mine.
