+1 for the remote greasing kit, but you still need to get under the car once in a while. To acsess the nipples better you can loosen the lower nut of the shock and pull it partially off it's bracket. Of course this is a hassle doing it each time you grease, so while you are there, change the original nipples for 45 degrees angled ones. Or you could mount the remote kit, but that is a little project...
