I have a patio screen door that use your 84-108 wheel.
one wheel is out now. Would you please show me how to install it back to the position, thanks.

Replacing the 84-108 rollers shouldn't be too hard. They basically snap into a circular cut out in the screen door corner like our 95-248. Also take a look the video below. It's a different roller, but it's the same principle.
