OK, I'm struggling somewhat... :cry:
I managed to remove the ball screw nut, however I can not for the life of me remove the recirculation tube by sensible means. I've tried several modest methods, but I really don't want to be too heavy handed and damage it further.

Anyone any tips to get the tube off?

I'm starting to feel hopeful it can be fixed now; it's just this damn tube is (hopefully) the last hurdle...

Cheers,
Dan
