One of the mechanical chappies will be along shortly with a link to the right place. You need to split the hub to get the bottom ball joint out. It's fairly easy to take off the hub cover, remove the spring/circlip off the shaft and the hub will slide forward giving you enough space to get the old one out.Carefull not to lose the shims from behind the clip if there are any. Good luck and keep us posted.
Light travels faster than sound.This is why some people appear bright until you hear them speak.
