You may want to take the knuckle off (spindle) and pull the inner axle. There is a oil seal behind the trunnion axle bushing that may be bad (differential oil in the knuckle). If your truck is fulltime, then I would do it. If you choose not to, there is a grease fitting screw in the bottom side of the housing trunnion. Take it out and screw in a grease fitting. Take the grease fitting out of the top and pump grease in until air is out and grease appears at the top.
