craigfocus

ive recently pit st170 brakes on my focus and i got a strange knocking and sound, i noticed the drop link was worn so i replaced them and the knocking stopped but the strange sound is still there, so im thinking of changing the wheel bearings and the bottom ball joints and as im a bit of a novice i was wondering if someone could give me a few tips, ive got a haynes but its for a normal focus and not the 170 which is where my hubs are from, thanks for any tips
