Expert Guide: Fixing the Oscillation Problem in Your Dewalt Sander

Our Dewalt Sander started jumping around and became difficult to control. We solved the issue by replacing the bearing in the sanding pad.

I just fixed my Rigid orbital sander and I’m one who’s unnerved by mechanical things. Your straightforward and simple explanation gave me the courage to try to fix it myself. I’d been searching for an answer to its problem and your video was the only one that told me what was wrong with it and how to fix it. And just think, I was about to throw it out and buy a new one. SMH. Thank you so much. Definitely subscribed.

I’m having the same issue with my Milwaukee RO sander. I’ll have to give your fix a try. When new, my Milwaukee RO was a great sander. It’s been used a lot, however, so I’m hoping the bearing can easily be cleaned (or replaced). Thanks again!!!

Thanks, I had jumping on a brand new DeWalt ROS, this was super helpful.

Thank you so much ! After changing the pad, spring and brake you found my problem!

What model are you repairing? I have a Dewalt 6421 random orbital sander that is vibrating. The bearing doesn’t come off with the pad. It has four screws holding the pad on.

I have a Dewalt DWE6423 and I find it awkward to control. it tries to pull in different directions. sometimes it chatters a bit. It's brand new. its a 125mm sanding pad but the pieces I was sanding were 80mm, and 40mm. its hard to keep it centered and it seemed to work better on the top or the bottom of the disc etc. but not sure that is a good way to sand

Well I'll be damned. Just took apart my jumpy Ridgid sander. Bearing is seized.
