they need to be greased. they have a film of grease so they arent "dry" but they need to be packed with grease after you install them. i have red'n'tacky grease made by Lucas, but if you go to auto-zone or advanced auto, etc. any automotive chassis lube grease will work. i would do it at least every 3k miles, maybe even more often, cant hurt to pump a little bit of grease to make sure its good. when it starts coming out around the boot its good to go
