Click on the top tab that is labeled search and type in what you are looking for. There are plenty of write ups and pictures on how to replace the ball joint on a w201. My suggestion is to just replace the whole control arm and that way you can get the LCA with the bushings and ball joint already pressed into place for you. Best to go with OEM brand for critical parts such as that. Welcome to the forum.
