So, I'm wrenching on a 1993 F-250 4x4 with auto lockers, trying to replace ball joints. So I'm gotten all of the clips and lock rings out here , and after doing some research I've found I needed a specific socket for this. However i fail to see how this socket removes what I need, but maybe I'm wrong. The more I research the more confused I get so I'm hoping to get a more specific response. Napa has the tool I allegedly need, but it's $50 and no returns so once I'm positive on what I need i will shop around for a cheaper one. Anyways, here is a picture of where I'm at and thank you in advance for the help!
