The 737 is the only airplane that I know that has shimmy dampers on the MLG and that are located at the knee of the scissors links as near as I can tell from the diagrams of the gear that I have seen. In order to absorb energy to keep the gear from shimmying there has to be some relative motion about the oleo centerline between the trunnion and the unsprung mass of the landing gear. It could be that after turning the gear will preload the damper in one direction or the other and results in basically a 'steering' input at the MLG and result in the characterisitc that you mention. Is the crabbing always in the same direction?
