Seized castor bush - new arm?

I sympathise with your struggle; over the lockdown period I have replaced all eight on my Mk1.

One sheared the nut on the front, one came out looking like a barley sugar twist, one needed the angle grinder and one released and will go in the spares box. The rears were easier in that two sheared and two are now spares.

All set for a four-wheel alignment now.
