I have been experiencing some rattle noise when driving over bumps  or broken asphalt. Its like a metal that rattles. (Driver side, i can hear it only when my windows are open  Cant hear it inside the car)

already replaced my suspension parts and all are brand new and genuine. 

tie rod inner outer, upper control arm and lower control arm ball joints and bushings, stabilizer link stab link bushings. Wheel aligned, wheel balanced. 

replaced brake pads to akebono and bendix, new brake hardwares (anti rattle spring, anti squeal shim kits) all guide pins are also good. Lubricated them too. Rotors are also good and aligned. Not wobbling when I inspect it. Also the pads are good. 

I don’t have any options left what to inspect. All are good. 😔

I only hear it when my window are open, its just so annoying.
