Been driving my Alfa for a while now and all of a sudden I've started getting REALLY loud sqeaking coming from the front right wheel. It's apparent when driving along normally but even more so when I steer. I mean it's horrific - like an amplified version of scrapping your finger nails down a blackboard. Could this be a suspension problem? I seem to remember an episode with a speed bump a few weeks back whereby I wasnt paying enough attention and drove over it at about 20mph without slowing down and thought the problem could stem from this but I've only just noticed the noise so am a little unsure. Any ideas on diagnosis/cost?
