Extend your slide-out section all the way. Bring the section back toward the RV about 6 inches. This prevents the seat from stretching and gives you some slack to work with.
Remove the topper or awning if applicable.
Grasp the edge of the top seal with the pliers and pull. The seal slides out of the track around the slide-out. Repeat with the sides, sliding the seals out of the tracks along both sides of the slide-out.
Measure the length of the top seal. Cut the new seal with the tube cutters.
Spray the track along the top of the slide out with Windex. This lubricates the track.
Slide the new seals in the track along the top of the slide-out with your hands. Do not use pliers; this may damage the new seals.
Measure and cut the side seals. Spray the tracks on the side of the slide-out and slide the new seals into their respective tracks.
Re-attach the topper if needed.
Open and close the slide-out to check the new seals.
