The rivets at the leading/trailing edge of the AXIS 24.1 slide out fasten the slide out frame to the coach body. They do not need to be drilled out to remove/replace the seals; they are simple held by an adhesive strip:
- Pull them off
- Clean the gluing surface
- Stick the new seal in place
- re-caulk the leading edge of the seal against wind-driven rain.
The actual seal <remove/clean/replace/caulk> took a day to do both the seals.
Suggest: DO NOT drill the rivets out on the AXIS 24.1, 'cause you'll just have to put new ones back in to keep the unit attached to the coach.
