I have a 93 Lude, and when i went to work 2day, and just as i pulled into the carpark! My car hada nut!
Its a constant chattering noise, i thought it might of been My lower pulley for my cam belt i though it was lose!
But once i poped the bonnet One of the crankshaft pulleys was wobbling, but its not lose and its not the bearings either!
But then again i'm not sure if that is what is cauing the problem!

A wobbling crankshaft pulley is definitely a problem - I don't know if it is causing the noise you described, but if it's wobbling it will eventually come loose.

On my car the pin that holds the crankshaft pulley in place broke and the pulley came loose - it made a loud chattering noise like you described. But when it happened to me my car died and the ECU threw a code saying the crankshaft speed sensor was screwed up.
