Noise that irritates and frustrates!!!!!

[s13feen]

I have a set of stage 3 tein adjustable coilovers and tein pillowball mounts and Ive had them for a little over a year now. I recently took my tires off to roll my fenders and clean up the wheel well a bit. After I did so I pulled onto the street and I started hearing a hard knock over every little bump and crack coming from my driver side front wheel well. I check to look to tire rub or rim rash against the well and, nothing. I tightened all the bolts on the control arms and sways ext. But I still have yet to find anything and its been driving me nuts for 2 weeks. Could it be I need to get that coilover re-valved, or adjust the pillowball mount? Idk and I thought I'd see what you guys had to say before I put too many eggs in one basket. I'd really appreciate any tips or thoughts.
Thank you.
