Having had the wheels off to paint the brake drums I thought I'd grease the axle as documented here. Found the little hole in the off side hub and cleared it with a 2mm drill. CXhecked that the nipple would pass grease and pumped three shots into the hub. Nothing came out the "vent" hole. I didn't want to put any more in in case it ended up in the drum! Could the grease have dried out after 46 years!. I note that someone has attemped to grease the hub recently (service at the dealer?) but having taken the nipple off there was little evidence that the grease had gone far (new was red colour old was grey). Should I leave well alone?

On the near side hub I couldn't find a "vent" hole at all no matter how much paint I removed. So I haven't put anything in there.
