I just replaced the stabilizer links in my 2007 Mazda 3 yesterday with Mevotech and they have zerk fittings. I added grease till I could feel some in the boot with my fingers as I had my finders on the boot as I was filling them up. I see many posts about this but don't know which is right, should you grease just until you feel grease inside the boot and that's it or should you keep going till it comes out of the boot?
