What is the best way to check if my shock is faulty? there ktr coilovers i purchased them brand new in feb this year, the reason i ask is i noticed a creak about two months after i purchased them and i thought it could be top mounts so i bought new and changed them around with the new spacers, the knock didnt stop so i looked on here to double check i fitted mounts right and i had but the creak is still there, its not majorly loud but its more of an annoying knock and creak really
