Default Superformance Cobra mkIII rear end rebuild
So I need to pull apart the IRS rear end to do my gears. While it's out, I may also do all bearings and cv joints. The question - what are the steps in taking this Ford 8.8 IRS out of a Superformance - pulling the hubs and cv joints then dropping the rear? I've already pulled the calipers and ds - now looking to pull hubs and cv axles. I figure I need to get that spinner adapter hub off to remove the axle nut. I just started with the 12mm hex bit to remove the nut/pins on the spinner adapter hub. What's the secret to getting these off without ruining the nut/pins?
