any takers? Does anyone know how to oil the motor bearings? | ||

Uh, not specifically. Um, more modern brushrolls use sealed ball bearings and so do motors. Not really supposed to be servicable, I mean depending on the bearing, you could maybe gently pry the bearing seal off and shove grease in there. But doing that without damaging the seal is like performing heart surgery. And if the seal is damaged, it'll leak grease fairly quickly.
Maybe someone else here has more experience regreasing sealed ball bearings? I suppose you could get an grease gun, and use a hypodermic needle type fitting to inject the grease through the edge of the bearing seal. Any sort of synthetic high temp grease should be more than good enough. For the brushroll though, idk about yours, but I've found that the plastic ones tend to get too hot and melt around the bearings, effectively destroying it. I would first run the machine without the brush or belt in it, and see if it still squeaks. If it's just a brushroll, depending on the age of the machine, a new one could probably be had from ebay. If it still squeaks, I'd say you're going to have to dismantle it and actually put eyes on the motor bearings and confirm they're ball bearings. | ||

See the thing about WD40 is... it's not really a good lubricant. It's so thin that it just runs down or just dries up.
I'll agree on one point though: you can't break what's already broken. Worst case scenario, you need some bearings. Ball bearings are fairly standardized, and come in all shapes and sizes. So not really a big deal. | ||

Yes but WD-40 is not for lubrication and not what it's meant for. Like duct tape is not for sealing your HVAC. You need SAE-30 non-detergent oil for electric motors with sleeve bearings. WD-40 can be used to remove old grease from conventional ball bearings, but not to lubricate them.
Follow MadMan's directions, but there is another post on here by a member who knows and has told instructions for re-lubricating both types of bearings. I forget his name but the post was fairly recent. Sleeve bearings get oil and ball bearings get grease (after cleaning them). A grease syringe will be a world of help. Just study good, and when you feel confident enough, tackle it. I've been reading up on it for months and I don't think I'm ready enough yet, but I do have the supplies. Just need to find out what specific paste grease to use and have a place to perform the surgery. | ||
