I have a ~2014 Czar with the journal bearings. I hadn't greased in a while and so tonight I cleaned up the zerk fittings and used the grease gun and super lube I got from Turn a few years back. But when I tried to put grease in the zerk it wouldn't take much or any. I could feel the ball being depressed in the fitting and I can also push in the ball and see it return fully when I push it with a small awl. I pushed the pump fairly hard in hopes of purging the pivot and seeing the grease push past the o-ring, but that never happened. What could be wrong?
