Thought I fixed coolant leak last week - I didn't, still leaking, replaced both suspension arms - still hear some banging when driving over small bumps, full geometry setup done - still doesn't corner well, front HID sensor keeps sending warning after arms change, cam sensor on it's way, cam gasket needs replacement.....aaarrggghhhh
Damn.... 
Checked drop links?
Steering idler ok?
Cam sensors lasts well, make sure you get genuine if you can. Same for gasket, cheap enough for 2.2/2.0 on trade here at least 
Genuine gasket around 40/50e, cam sensor around 100

, the wheel has no play, drop links fine, ....really don't know what else could it be.
Imagine an omega parked all night, you put into reverse, after a few yards press the brake and hear the muffled bang from the front, it's not the brake itself, like something moved where the suspension arm is, really can't figure it out
