The captive nuts are accessed via a hole in the subframe

I also made sure the new arms were well coated with wayoyl

Captive nuts are square and reside in a pocket on the subframe, and as you point out are accessed through an hole.

Good pics Steve - tell the story about accessing them very well - was once told a picture often replaces a thousand words!

My rear arms fought Kevin in Wickford every inch of the way. And seeing as you're in North Wales l would have thought you'd have used Jules too.

This pic from Steve shows the nut?

The nut is NOT welded in place, but held in a formed slot, of folded THIN steel. If you have to put any significant force on removing the bolt the folded steel will giveway.

What's the course of action if the captive nut lets go.
Does a new one need to be welded in.
Many Thanks,
John.

The nuts are held in a cage, it is the cage that lets go.
The cage if not to badly damaged can be welded back in place and the nuts reused.
the sub frame needs to come off.

You can access the pocket nut while the subframe is on the car, therefore you can get some plusgas on the thread, and also tep the sides in on the pocket so it grips the nut more if it's starting to or feels like it will not move easy.

Maybe even add some liquid steel mix and let that set to aid removal of the bolt.
