Fox Mustang Weatherstripping Replacement
For many of us, our daily drivers sit in our parking spot at work all day, taking a beating from the sun, wind, ozone, and other elements. Rubber-based products don't last forever in this kind of environment, and sooner or later you find crumbling weather stripping, dried out window trim, cracked window gaskets, and much more (one reason auto manufacturers went to glue in glass instead of using a perimeter rubber gasket product). It's especially rough in the Sunbelt-Florida, Texas, California, and so forth. Owners in these states know all too well how the sun, ozone, and even acid rain chew through black moldings like a termite through wood. Sure, you can use a car cover if you keep your daily driver spotless, and you can try rubber conditioners and other magic in a bottle solutions, but over the years these rubber parts simply dry up and wear out.

One of the worst areas for this problem on Fox Mustangs is the door glass. Being a full frame door, the glass rides and seals into a rubber channel in the door frame. Further more, the glass has "dew wipes" on the inside and outside of the glass, also called belt weatherstrip, and finally, there's rubber-based trim on the door itself and on the A-pillar leading to the large fixed quarter glass. All of these rubber parts are exposed to the elements and are not immune to wear from the window movement, and aging over time. Just think how many times your door glass has gone up and down over the last 15 or more years. Our '90 5.0L LX hatch has certainly seen better days and has a whole grocery list of troublesome fixes to tackle, but one of the most pressing, and annoying, was the fact our dew wipes were rock hard from age and the soft felt-like inner lining was completely worn away from use, causing the door glass to squeal loud enough to turn bystanders' heads our way. This moved the repair to the top of our fix-it list. The work is fairly simple, just a bit time consuming. We found everything we needed for our project at Mustangs Unlimited (and it has a lot more door items if your Fox is in worse shape than ours) and we got everything in just a few days. So check out our tool list, order up what you need, and follow along.
