In the middle of a project yesterday my router went crazy and started screaming. I pulled it apart and gave it a dusting. The manual says nothing about lubrication. Am I supposed to be lubing it somewhere? Is there something I’m missing? Perhaps it’s just its time to go. Any help would be appreciated.

Most routers have sealed bearings to prevent dust buildup…How old is the router and what make and model #?

Maybe the bearings are replaceable, and maybe it’s time for a new router.

Did you check the brushes? Sometimes when they are near their lifespan they can scqueel.

Several years ago a friend used my small Bosch router in the router table to round-over dozens of oak slats. Went at it for about 8 hours. Had to replace the bearing. But I don’t remember it screaming—just wobbling!

The brushes? Are those the rectangular thingies that gave me trouble when I was trying to put it back together? I’ll have to look into this. Thanks for the tips guys.

If you have a decent router, it may be worth looking into replacement parts. Some of the older machines are a lot better than the new versions. I have 2 older Porter Cable sanders that I’ve kept going for years, by replacing bearings, belts, etc. The new ones are junk, so these will keep getting transplants until the parts run out.

Yeah the rectangular black thingies are the brushes. These wear over time and can start the squeeling especially if they have worn down so that their housing is abrading the rotor of the motor. Generally the motor can’t run if you have no brushes left but if they are damaged they may still work but be noisy.
