Sliding rear window

[truckster]

It's an easy install, but you'll want a helper.

To remove the old glass: Have the helper in the bed, and you'll be kneeling on the seat facing the window. It helps if you have a hook tool, which looks kind of like a screwdriver handle with a hook on the end. Start at one of the upper corners, and pull the gasket down over the pinchweld while you're pushing out on the glass. Keep going across and around until you get the whole thing out. The helper is just there to catch the glass.

Put the gasket on the new backlight, and lay it down with the outside facing down. Take a 3/16 or 1/4 hollow braid nylon rope and work it into the pinchweld channel in the gasket, with the center of the rope at the center of the top and the ends crossing at the bottom. Have your helper hold the window against the pinchweld and put some pressure on it, and pull on the rope so that it pulls the rubber over the pinchweld. A liberal application of glass cleaner on the rubber will help it slide over the pinchweld. It will usually take one or two firm but not too hard smacks with the open palm of your hand from the outside to completely seat the glass. No sealer should be needed, unless the rubber is torn. If that's the case, I'd replace the rubber.
