Mine started rattling again on Saturday, I took tact's advice, stopped and spun the little roller and hey presto! squeak gone (for a while anyway), so I'll tighten up the strike plates when I get a chance.
Now who's going to tell me how to get rid of the clutch pedal squeak..?
Also, what's the loud springy "BOING" noise from the drivers footwell when I hit the pothole at the end of my driveway every morining? Something to do with the brakes I assume?
