Paul -- you were @£$%ing lucky, I had 2 days of fighting to get it all apart last week to replace to re-present to MoT tester today.
Peter, Draper make a joint spreader 2-tined fork looking thing that one hits (rather therapeutically I may add!) to split the join apart. Then Bob's your (incestous) Uncle to get at the ball joint…..good luck!
As Mine hadn't been apart in 12 years, I've got several new tools now including a tap-n-die set, some groovy mole grips, and a face-off rather large 2.5Kg mallet.
