2 cents (Warn Hubs)
Drilling a hole and trying to get silicone to stick (with all the grease) sounds kinda iffy. The air pressure in a hub can change suddenly and dramatically when water is splashed on it, and would probably be enough to blow out or suck in the silicone.
After fighting with a pick the first time, I put a very subtle bend in each end of each ring on my truck - not enough to cause it to interfere with the cap - so that I could EASILY slip a pick or small screwdriver under it anytime since then. It works really well (after the initial exercise) and poses no chance of letting mud in or grease out. JMTCW
