ABSTRACT:
Flexible drive shaft, lubricated by a suitable grease, rotatably mounted within a flexible casing routed within a vehicle from an input to an output tip connected to a deflection instrument. The drive shaft and output tip are designed to pump the grease to a collection station so that collected grease serves as a cushion to limit contact of the drive shaft with the interior casing to thereby provide noise abatement for the rotating drive shaft.
