A non-hydraulic shimmy damper that can be mounted to existing aircraft landing gear and does not substantially interfere with steering or require significant maintenance. When the shimmy damper requires maintenance it can be readily swapped out as a line-replaceable unit (LRU) thereby reducing aircraft downtime. The shimmy damper is mountable to an aircraft landing gear strut and includes a rotatable coupling member that engages a rotatable steering member of the landing gear strut. A damping assembly is coupled to the rotatable coupling member to provide a damping force. The damping assembly is adjustable so that a desired amount of damping force can be applied and/or maintained.
