How to Replace a Rear Window With a Slider

Trucks come with lots of different options, including solid back glass and sliding rear windows, also known as a slider. While a solid back window offers added security, a slider will allow wind to flow easier throughout the cab, making driving with the windows down a more comfortable experience. It also allows communication with those in a camper, if one is mounted on the truck. If you want to install a sliding back window in your truck, you can do it yourself with the help of an assistant and some hand tools.

Things You'll Need

  • Flathead screwdriver
  • Assistant
  • 15-feet of 1/4-inch rope
  • Slider rear window
  • Open the cab doors and use the flathead screwdriver to work the rubber seal around the back window out from the inside of the vehicle towards the outside. The flathead screwdriver can push the rubber lip out, then can be drug around the mounting lip to remove the rubber. Make sure the assistant is holding the glass from the outside while you are pushing out the seal. Then remove the back glass.

  • Place the rope in the rubber seal around the slider window, leaving at least 12-inches of rope hanging outside of the rubber seal. Make sure the rope goes around the entire perimeter of the glass and stays in the channel.

  • Place the window in the window channel on the cab of the truck with the excess rope on the inside of the vehicle. Have your assistant hold the glass in place while you move to the inside of the vehicle.

  • Start to pull one end of the rope, parallel to the ground, while the assistant pushes the glass in towards the interior. This is going to pull the rubber seal out and around the factory lip, mounting the glass in place.

  • Continue to pull the rope around the glass while the assistant follows you, pushing in the window. Once you've gone around the entire window, you may have to use the flathead screwdriver to pull some of the rubber seal towards the inside of the cab, just to clean it up a bit.
