Suspension Grease fittings

Went to grease the zirks on my suspension before our outing this weekend second trip on the new unit and three zirks wouldn't take grease as if they were plugged and suggestions on getting grease in them

It's possible that the fitting itself is bad. I changed mine out for a 90° fitting so it's easier to get on it.
It also maybe dried up solid in the hole of the bolt. In this case I'd pull the bolt, remove the fitting and clean out the hole.
And/or you may have to lift the coach up by the frame to unload the suspension so the grease can escape from the hole to the bushing.

Heat on zerk fittings will usually loosen them up. (heat gun or torch both work great).
