replace just the wheel on the bottom of screen door

Is it possible to see a few photos of your door, especially the section with the wheel you are trying to remove? That would help us come up with a solution.

Thank you for your patience. You could theoretically replace just the wheel, but since your wheel is riveted in that would be difficult to do. See our 84-017 for one possibility, though the screw could get in the way. I would try to replace the complete roller. If you want, remove the complete roller from your door so we can identify the correct part.
