How Can I Stop Squeeks and Rattles

Q--With the ever-increasing use of plastics in instrument panels and dashboards, what can I do to stop those annoying squeaks and rattles? Is there a spray material that can be used? If so, what is the name and where can it be purchased?

A--Squeaks and rattles, officially called NVH (noise, vibration, and harshness) in the industry, are the bane of many a mechanic. The book time usually doesn’t cover his actual time. As a result, plenty of cars get the “sunshine treatment.” The car is parked on the lot for a day then the customer is called and told it has been fixed. Bunk.

I have had a modicum of success using silicone spray, but the benefits are temporary. In the industry, they use a variety of peel-and-stick products, usually having one felt side. Check out your hardware store for things like green felt dots that protect furniture to thicker felt pads for chair legs. The fuzzy (loop) half of Velcro also works well for some applications.

I suggest using a business card as a wedge or bushing during the down-the-road diagnosis. It doesn't matter if the sun isn’t shining.
