When on the final spin washing machine makes very loud rattle, thinking it was the drum bearing I removed the spider both bearings apear fine no sign of water damage and are perfectly smooth when turned with a finger. If I replace the belt pully so I can turn the drum then it is still makes a grinding noise from the front of the drum admitedly the machine is face down and if I pull the drum up then it turns freely. Should I bash on and replace the bearing ie is it only broken when under lots of load, or could there be somthing wrong with the drum?
