Lower Ball Joint - testing my patience - picts

[Shugalou]

Hi Guys,

I'm prepping to install my 4/6 drop and I'm rebuilding my lowers and I'm trying to figure out how to get these SOBs out.

I have taken a grinder to them wacked on them, put heat and nothing yet.

It looks at though there is a collar that holds it on.

Does anyone have any insight? Am I on the right path or have I totally frigged this up?

I originally gave these to a shop to do but they sat on the job and told me at least another week and 200 bucks so I'm trying this out on my own.

Thanks
