SUNROOF RATTLE
By Steve Grosekemper
You are driving along enjoying a perfect southern California day in your 911. You decide to open the sunroof to take in the sights and sounds of the birds
singing and the wind whipping by. You gently push the switch and listen as the sunroof rolls back. But instead of the sounds of nature's symphony, you are overcome with the sound of marbles in a tin can.
Since the perfect drive on the perfect day is not compatible with this
wretched noise, you reach up with your hand and push and tug on the sunroof. As you do this the tone and volume of the marbles change but they do not go away. Your thoughts now turn to those rotten neighborhood kids and how on earth they could have gotten all those marbles in your sunroof anyway! Fortunately, the likelihood of you having to fish out a dozen marbles is fairly low.
What has most likely happened is that the sunroof guide felt has
deteriorated, resulting in an unwanted metal-to-metal contact. As the sunroof lowers and slides back into the roof, it lays down onto the sunroof rail. If the rail felt is missing (see figure 1) the metal tab lies onto the metal sunroof rail causing the aforementioned bag-o-marbles clatter.
One would think that the repair would be as easy as ordering a new felt and performing a quick installation. While that is a great idea, there is one catch. In order to get the felt you must purchase a
new sunroof! I prefer to make a
trip to the hardware store and pick up a few adhesive felt pads strips like the ones used under furniture legs and such. After a quick trip to the hardware store follow these steps to eliminate the noise.
1- Open the roof about 2 inches.
2- Gently pull down on the leading edge of the sunroof headliner and separate it from the sunroof.
3- Slide the headliner back all the way and locate the missing felt pads towards the rear of the sunroof.
4- Flatten the existing tabs and attach an adhesive pad in its place.
(See figure 2)
5- Re-install the sunroof headliner and drive the car to verify that all rattles are gone.
