Outer Limits 4x4 Board

Just replaced nearside track rod end with Nissan item. On the face of the knuckle there is a hex nut that I assume unscrews to fit a grease nipple for maintenance. Is this so? Do joints have grease in them from factory as mine seemed quite tight to move by hand

Yes, remove the nut and screw in grease nipple. Pump in a small amount of Moly Grease.
