This could also be part of a sound deadening thread, but left over pieces of that Noico sticky butyl material make a great cure for rattles and squeaks. Just cram it into small spaces and it sticks great. I use it under screws, along plastic contact points, under connectors, or anywhere else where something can bump or slide against something else and make a sound. I learned that when I worked at a used car lot in high school in the 1970s. We had something similar and we could make someone's old trade-in sound as tight as a new car.
