After getting under the wagon last night, I'm thinking of replacing the front control arms as well. Looks like the front control arms have the ball and bushings all in one unit (FEBI). I saw the DIY for the older w124 where you can replace just the ball joints but should this job be a little "easier" as it's all one unit and I don't have to deal with removing old ball joints and pressing the bushings out/in? Any special tools needed?
