OK, another stupid question?
My new ball joints don't have zerk fittings, and it appears to not have any grease. I have the little needle injector, but that seems sketchy. Naturally I can't master the search function.....
Any thoughts?

They are lubed internally. Don’t mess with them. Zerk fittings have gone the way of the dinosaur unless we are talking about heavy duty trucks.

OK, thanks.
