I did Gerry.
I hand pump the grease in. Yes Ive seem them blown. I did one myself. Never too much till it see it oozing from inside the wheel. I guess even by hand you can over pressure.
They are "almost" idiot proof. They are spring loaded to push grease against the bearings. You can how far the cap w/ zerk had recessed. Anywhere in between till it maxs out works. Over pressure blows seals on inboard bearing side.

Also I heard the best time to grease them is after running the trailer a bit to get the existing grease and bearings warm and they accept the grease better??
