Abstract
A silencer assembly for trailer hitches and a method of use thereof. The silencer assembly includes a sheet of material that is durable, abrasion-resistant, wear-resistant, ultra-violet light resistant, and sound dampening. An adhesive is applied to a bottom surface of the sheet which is then placed on a portion of the drawbar that is selectively receivable in a bore of receiver tube of the trailer hitch. The adhesive fixedly secures the sheet to the drawbar. The drawbar is inserted into the receiver bore. The sheet occupies part of a gap defined between an exterior surface of the drawbar and an interior surface of the receiver tube reducing relative movement between the drawbar and the receiver tube, and thereby reducing rattling noises. An additional sheet of material and one or more shims may be used to further reduce the gap between the drawbar and receiver tube, and thereby further reduce rattling.
