OK got a question. Can you guys grease your U-joints while they are installed? I can't It's a PITA having to take the shaft off to grease them. I can almost get to them, but the yoke is just in the way by 1/4" or so. Can I get a different style zerk? I know the grease fittings on our aircraft take a big needle style grease tip. I could also grind a little notch in the yoke, but thats prolly not good for it, or do I just need a different tip for my grease gun? My grease gun looks like this with the soft hose.
