Last Rites?

This old vac has started screaming. All the bearings that I can get at seem to be ok but I've cleaned an re-lubricated them anyway. This leaves just one, in the sealed end of the motor, if it's this  one we'll just have to write it off. It doesn't owe us much, neither of us can remember  how old it is but it cleaned up Samoyed hair for 30 years before being relegated  to bedroom cleaner so that we didn't have to keep carrying the newer cleaner up stairs.
