Went to grease my bearing buddy on my boat trailer and noticed the nipple had fallen out. I looked at the nipple to see if it was damaged at all but it wasn't, just looks like it backed it's way out. Now I can't seem to get it to theard in? I can hold the nice to the hole and put the grease gun on and push grease in but the nipple won't stay. Do I have to take the bearing buddy off to try and put it back together?
