Anyone out there ever change bearings on a modern Craftsman router model #320.17541? To me it looks like a sealed unit but there are bearings listed on the parts list. That gives me the impression that it can be done. Any good ideas on testing them other than spinning the shaft and listening and feeling for friction?
Can anyone give me an idea how long the bearings should last anyways? I don't feel like they should need replacement. The tool is about 6 years old and has only seen moderate use, mostly in a router table. What's leading me to think the bearings are bad is how the thing screams and vibrates in the router table. I took it out of the router lift and tried it in the regular base and its been so long since I've used it that way I just cant tell if the vibration is more than it should be. What I can say is that its not screaming like it does in the table. It may be that the lift is the culprit but I have taken it out and adjusted it before only to get the same result.

How do you know you're learning anything if you don't screw up once in awhile?
