This is easy, I thunked, as the top balljoint seperated with a forked splitter and a few minor whomps with a small hammer.
Then the lower bastard - the forked splitter wouldn't budge it even when being "carefully" whomped with a sledgehammer. The wind-it-up splitter was then employed with a spectacular lack of success, mainly due to the amount of sideways play in the two parts allowing the bolt to slip off the bottom half when under a lot of tension.
I've now fitted two washers to the splitter to take up the sideways slack but I have a sense of impending doom about it, TBH.
Is it worth leaving the joint under tension for a while? Heat's not really an option.....unless I remove all the rubber and grease from the ball joint.
In short, bollocks!
