There are two sounds I've experienced from this area under the car, one is a distinct crack or loud pop. For that, doing what Jason has illustrated will solve that one. Next, is a dull rattle from the right rear of the car at slow speeds and when traveling over uneven surfaces like expansion joints and the like. I believe I've found what might be causing this rattle but not sure on how to rid my car of it. In the link below is a short video of me under the car with a handfull of brake caliper. Listen to the sound and see if that's the same noise some of you might have.

The calipers are a floating design to allow them to move in and out when the piston expands. The amount of play you seem to have would indicate that
#1 - The grease on the guide rods is all dried up which is why it makes that clunk sound and
#2 - the caliper has been moving without grease and worn the guide rods down allowing them to move around more than they should.
I would recommend getting new guide rods and then lubing them with high temp caliper lube.

it sounds like your caliper bracket isnt bolted in tightly, but that would be too easy of an answer

Lol, sorry, i do understand how they can wear down due to friction, it just seems that unless someone slams on their brakes, the friction would be almost nonexistent, those guide pins don't move much under braking

In the time since my last post I went to the parts store, picked up a bolt/slider pins set and swapped out the factory hardware on both calipers. The slop shown in the video has been completely eliminated. I won't be able to drive the car to see if the sound is gone for an hour or so. I'll post what I find.

Im having a clunking noise on my car only its coming from the front end (very prominent on the passenger side). Everytime I go over cracks or sharp potholes in the road its so noticable and it pisses me off. Im just wondering if my passenger side coilover is loose because Ive had it off so much (had to get my QA1s revalved and now its making a squeeking noise because i think its leaking.) that I may have not tightened something up to specs.
About a year ago I had a clunking noise from the rear everytime i went over long cracks in the road (no speed bumps or of that nature). I just tightened up my panhard bar because it was loose and now, no more noise from the rear. Just typical vibration from the rear everytime i go over the same cracks in the road.

Everything else can usually be checked pretty easily.
