When's the last time the belt was replaced? Does it make the noise with the belt disconnected? |

Another thing, when belts that old get slack and squeal it means there is frictional cooked hard rubber on the brushroll and motor pulleys from the belt initially slipping long before it becomes audibly evident. This dark glaze buildup does affect the perfect roundness of the pulleys causing even more high speed vibrational damage to the belt & pulley bearings. Bearings are usually more than up to the task, tho. When changing any belt I run the motor with the belt off and run a steel wool pad along the shaft to clean it absolutely. Same goes for the brushroll pulley surface but manually. And always always dissassemble and clean up the brushroll bearings and caps of impacted dust and hair coils. Human and Pet Hair being the same composition as fingernail clippings, both organic kerotin substances are more abrasive than one might think. :-) New belts are a struggle to get on but the ease with which old ones come off is the proof of how much they stretch - influenced by contact with the hot motor armature as it does it's work of turning the brushroll against carpet resistance.
