My Hoover quattro system 1300 washer dryers drum bearings have started to get noisy. Is it possible to replace the bearings or is it time to get a new machine. I've had a quick look and It looks like the whole drum assembly will have to be removed then separated to get access to the bearings, are there any website with exploded diagrams/part no's etc.Alternatively whats the going rate for this type of job.
