I did ball joints recently on my valver, the 16v ones arent a taper fit as on moist cars, but instead are held by a pinch bolt that locates in a recess on ball joint, through a clamp. This bolt (on both sides) sheared on trying to loosen them, and so this made it harder to punch them out. Tip, get a screwdriver of a suitable length and use that to lever clamp slightly apart, as this will allow you to retract pinch bolt easier (liberal WD40), whether it snapped on you or not. Then use a ball joint splitter to seperate hub from ball joint (have to spread clamp a little again). Once out, be carefull not to let strut move about, as the night mare scenario here is you forceably pop the inner cv joint out of the gearbox (valver boxes can be damaged this way). To get new ball joint in, loosly bolt it to wish bone and then try and get ball joint shaft up into clamp, its awkward but keep your patience and take youre time, as it is easy to bugger a new ball joint by brutalising it. Again avoid swinging strut all over place, and any other pressure on inner cv. Once its slid into clamp (again spread it with a screwdriver to ease it in), its just a matter of putting new pinch/clamp bolt in and tightning wishbone/ball joint bolts. I got my trackjing done after as upsetting ball joints can (and contrary to common opinion) put your tracking off, but since you are doing track rod ends anyway, youll have that covered. Dont know if this helps you, but let us know how you get on
