Just got back from parents sunday lunch mmmmmm!
Anyhoo, got the drivers side off and replaced in abour 30mins, was going nicely!!
got to the pass side and the bottom ball joint bolt was seized after an hour of banging and clattering it finally came out!
wapped the new WB in then as I tightened the bottom ball joint back up the threads stripped

another hour of banging and clattering finally got the bolt back out found a suitable replacement (in the "box of bits") wapped it on and bingo all done.
TBH it doesn't feel that much different, the old bushes were shot at though so it was worth it, maybe after a decent alignment it will be better.
The steering doesn't fully come back to the centre, hopefully this is just the camber, what else could it be??
