Cusco Coilover noise???

[EMPANADAZ]

so i just picked up some coilovers from a friend,the front are cusco zero2 and the rear are zeal function x all for $450,deal?not so much,i installed the coilovers and when i took her out to see how it drives i hear a weird "thump" noise coming from the front driver side,so i pull over and put pressure on the fender to hear the noise again and sounds like its coming from right under the top mount.I have ran out of idea's,the sound is not super loud but its noticeable and annoying,these coilovers have what looks like 2 metal bushings towards the top of the coilover.If anyone has any suggestions or has had the same problem feel free to speak
