Did you get the UJ changed then? If not I'd suggest a socket and a vice with plenty WD40 to get the cup moving, with regard to the balancing weight I'd get your local mechanic to tack it back on, unless you've got a welder yourself, not sure if the cable tie idea will hold it tight enough when in motion, where about are you? Might be someone on here local that can tack it back on for you?
regards,
Jim
