At least one noise isolator comprising a coil spring shrink fitted at one end to an inner housing and at the other end to a cover. The inner housing is inserted into an outer housing with a damping compound between and potted to the inner and outer housings. Additional damping compound is bonded to the base of the outer housing separating the base of the outer housing from the base of the inner housing. The cover, having damping compound bonded thereto, is coupled to the outer housing. A hub, positioned adjacent to the damping compound on the cover, is coupled to the inner housing.
