Click / snap from front suspension while braking
 

I installed coilovers and replaced all of the control arms and I have a snap / click that comes from the left front suspension when it cycles down. For example, when I'm approaching a stop sign and apply the brakes I get a single click from the suspension. If I turn the wheel hard left/right while going slowly I will also get the click when turning right causing the suspension to load the left front. Same thing if I go over a speed bump at any speed, once the suspension sycles I get the click. I cannot reproduce the click while sitting still. The car is about 1.5" lower than stock and I was just under the car and can't find anything that's loose. Nothing looks to be moving. The CV axles are both brand new, replaced at the same time as the suspension work.

Any ideas of where to look next? I'm planning to go back over every bolt in the front end and pull the coilover and make sure that the spring is oriented / seated correctly in the upper mount. Other than that I'm stumped.
