Dust Collector Squealing

Sounds like bearings to me… or the impeller is rubbing on something like a piece of wood. Spin it by hand and check for debris that might be interfering. If it's the bearings, that is an easy fix and will set you back about $10.

I took the cover off and spun it earlier and I don't think it has any debris in it. How do I go about replacing bearings?

Pull the motor and crack it open. It's just 4 bolts/nuts. You usually can replace them without any special tools (like a bearing puller or splitter), which based on your question, I'm guessing you don't have

The hardest part might be separating the motor from the impeller. If that goes well, the rest is a piece of cake. The first time I pulled my impeller I had to take the thing to a motor shop where they used an acetylene torch to heat it up and pull it (I was working on a different problem than you). The second time I did it, but it took a fair amount of pounding with a brass punch to do it. Impellers don't lend themselves to just using a normal puller to remove.

Sounds like the bearing to me as well. You may not have to replace them, try lubricating them first. If you can disassemble to the point where you can get at the shaft, use a grease with teflon, then reassemble.

This one such grease. (I use the one available at HF and other retailers):

When it comes to wood working machines in our shops, it is a good time to learn and not fear changing out bearings

I had one do that. Checked and the impelller was lose. Tighten it up and the squeal got even worse. Took the impeller back off and it was one that has a bearing in it. Replaced the bearing and all has been well now for about 10 years. Could be a bearing in the motor also.

You can take your motor to a motor shop and let them replace the bearings. It costs a little more. But it is better than replacing the motor.

And that's exactly what I did. Found a shop not too far via Jet's service center page and replaced the bearings for $50 in two days. Thanks for your help everyone!
