Quick repair rear door gasket leak suburban?

Answer 1

First make sure the gasket is clean in front and behind it, removing dirt and debris. Dry everything completely and then use a hose in short bursts in specific spots, one area at a time until you find the leak. We found that stuffing thin polyethylene foam between the gasket and car-body bulked out the gasket at that spot enough to improve the seal to the door. Probably a length of thick foam weatherstripping added beneath he rubber gasket might work too, depending on where your leak is and how bad it is. If that does not work, you can order new gaskets for about $100.
