I just recieved my new sway bar end links. I ordered the Moog brand that has an grease fitting in them. Question is do they already have grease in them or do I need to grease them up? If I do need to grease them, what kinf of grease should i use?

 

I know I had to add some grease to the upper ball joints that came in the new Moog upper controll arms I got. They have a little in there from Moog, but you have to add some. Any grease will work that goes in a gun. Like wheel bearing grease.
