right i first heard this a little while ago but since all this cold weather started i hadnt noticed it as the windows are done up. was driving around today and for once had the window open and there is this bloody ticking noice coming from one of the wheels (well think so, sounds like the front driverside). just a constant ticking thats the only way i can describe it, the faster i go the quicker the tick gets. has anyone got any idea what this is cos its so annoying.
