Part identification

[Creekchub]

Does anyone know the name of the part circled red in the picture? It’s a threaded nut with a grease fitting on a stick steer motor that slides through the fitting. The seal blew out the fitting so it will not hold grease now.

 

[LDUBS]

"Steering tube grease nut". May not be the official name but if you search this phrase you will get a lot of hits.
