Any good ideas on how to remove them. My left rear broke today.

I used penetrating oil and grunted until the pigs came home and still can't get it off.

I haven't even tried the connection at the rear wheel yet,,,, I'm stuck on the bolt attached to the sway bar.

Car is W123, 1977 300D.

Whew, this looks like a real knuckle buster.
