Just an FYI for anyone still with the old style Andersen WHD ball mounts with the exposed friction cone. I can't find the post (circa 2022?) that started me down this road (about horrible noise from a wet Andersen ball cone) but we encountered this after a night of rain during our last trip. It was still making noise after a week of dry weather.
I did find a Service Bulletin from 2018.
I called Andersen and was told I could replace the friction cone under warranty or I could upgrade to the newer style ball housing and triangle plate (whale tail). The price has increased but is still pretty reasonable compared to full price replacement purchasing the parts. The upgrade now costs $150 and includes the 2" Ball, Ball Housing, Triangle Plate, Friction Cone, Snap Ring, Pin and Clip. The 2 5/16" ball may be available also.
