  • Patent number: 6811005
    Abstract: A resilient device for minimizing noise in a splined connection includes a mounting portion and two flanges bent from the mounting portion to attach to a structure. The flanges are substantially parallel and spaced apart from each other by the mounting portion to form a substantially U-shaped profile. An arm is bent in a second direction from the mounting to lie adjacent to the mounting portion. The arm has a wavy portion having a pitch that allows it to engage with splines in the splined connection to prevent rattling in the connection without having to reduce the clearance between the splines.
