Rattling sound on front left of the car

So I keep hearing this rattling sound under the front left of the car whenever I go over a dip or bump. Also when I go over 80 car starts to wobble and gets worse as I accelerate. So I figure it has to be something suspension related.

I popped a tire Saturday on a pothole and had to get the car towed and replaced the tire and do an alignment. When I did my alignment the front right was off -.01 on both Camber and Toe which I thought it was funny since I was barely off the specified range

The rest of the car was fine except the front left Toe was .43 and the range is .02 to .19. Had the car aligned, it was straight again, but I still hear the rattling sound when I hit a bump or dip and it seems sensitive to going out of whack the moment I hit something so I figure something is loose or needs to be replaced.

Anyone have any suggestions on where I should look? I had bushing replaced 10k miles ago but I don't think its that since the cambers weren't out of whack. Maybe I need to tighten somewhere where the control arm meets or replace it entirely?

Unload suspension, get your favorite pry bar and start checking things.

It is most likely your radius arm, but it could be other things.
