Default Suspension troubleshooting

I've been having a very loud suspension crunch for about a week now. I've narrowed down a sure fire way to reproduce the noise by "bouncing" the front drivers side above the wheel. As I was trying to troubleshoot I put the car on ramps and had my sister (only person avail) bounce the front end. I could tell the noise was coming from the head shield area (not the heat shield).

So I take silicone spray and coat the lower shock mount... bounce the car, nothing changes, then I do the same to the tie rod end and lower ball joint. Nothing changes. So I give up and drive home... I decide to go to rite aid to buy batteries, so I can use my camera to make a video so I can get some help from the forum on the sound. When I come out I bounce the front end and guess what.... no sound...

So with the sound narrowed to LBJ, Tie rod ends or lower shock mount which would make a crunchy/squeaky sound when loading/unloading the suspension from directly above?

After checking prices at rockauto and finding out that advance auto price matches rockauto I went for both... I got LBJ's and outer tie rod ends for 210 or so... Beck/Arnley branded on all of it.
