i have noticed a knocking sound from drivers side front wheel over bumpy roads but only very faint, havent really looked under there yet, its not long had an MOT so it can wait, i dont even know if it has wishbones or not, havent had the car long so not an expert on it yet :p hope it isnt the rack!
it started since i had a good rag round on a gravel car park and hit a nice big bump

hasnt effected the front tyre wear or the steering (that i can notice)
