Intermittent clicking/loose bolt noise in front passenger wheel well.
I just recently had to put a new air shock on my front drivers side of the car and about a week into it I notice the most jarring noise coming out the passenger side front wheel well when I brake. It sounds like a clicking noise between two metal surfaces or the sound something would make if the bolts weren't secure and stripping. The noise is pretty much intermittent but it usually comes on strong after a full day of driving when I brake or when going down hill and braking. It is also typically associated with right turning although it rarely makes this noise while accelerating or reversing.
I thought it may be the suspension but it does not make this noise if i drive in a straight line without stopping, even if I do hit some bumps in the road no noise. It is primarily associated with braking. If this was the suspension wouldn't this noise be constant?
I took it to two mechanics one says its a control arm bushing the other is saying it is the air shock itself. The airshock seems fine it does not lose air and I didn't even think it had many moving parts to make such a noise. And if it was a control arm bushing wouldn't the noise be constant or atleast present itself when driving straight over a bump.
I live on a hill so I get to hear this noise every morning on the way down and it pretty much disappears once I reach level ground and try to show it to a local mechanic. Sorry for the essay wanted to make sure I was clear.

It could be this piece also: the one that keeps the spring in place. It`s a very cheap one, DYI job.
