rear suspension

I bought the upgraded bearing hubs from DF, do i need to take this housing pictured off the old bearing hub and put on to the new one?

Hey everyone. I'm spending today working on the rear suspension. I'm past the point where the videos end so I'm kind of flying blind. I do have all the manuals for the Cobalt so I'll be referencing that for torque specs and whatnot. My question is... how do I get the rear shocks to attach to...
