thanks for the suggestions, the year of the car is 2003, both front struts, springs, top mounts and top mount bearings were replaced about a year ago, so i'm thinking its probably not that, the knocking was present when the MOT was done so was surprised myself that nothing came up as at least an advisory, I will get the wheels balanced but the tyres seem to be wearing evenly, do you think the wishbone bushes could knock similar to the sound the drop links make?
