i suggest please get the front axles checked. the clank like sound at turning in either direction, most likely the front axle-cross [inside GODA] are wearing out resisting smooth return while car is moving. Nothing to do with the diff, transfer case, steering box, you can test by removing the front drive shaft [ 15 min job ] and driving here & there right left circles for a while. The sound / lock jerk will remain there. check for any visible greasy leaks at front wheels from under carriage. @goshi_mirza
