You ask a very important question. Can these handle the static axial load of mast and antennas? http://www.wholesaleimportparts.com/driveshaft.php for a picture of one with mating assemblies. A compl

Grant, From what I read their main function is to dampen the torsional shock loads. Here is what Mercedes Benz says: "The flexible discs serve two functions on the vehicle. Primarily to absorb excess
