Swing hub outwards so the track rod end is easier to get at, undo nut and remove tre by giving the steering arm a whack with a hammer where the pin of the tre goes through, A two pound hammer is about the best size.Now place a jack under the lower wishbone where the ball joint is located and jack up until the shocker starts to compress a little, undo lower shock nut [11/16af] and pry away shock from mounting pin, lower the jack under the wishbone, this allows for the the tension on the joints to be released, easier and safer than chocking up the top arm. The next two steps are not mandatory but it makes it easier, undo brake calliper [and cable if fitted], hang up brake calliper up to prevent strain on brake hose, undo cv nut and tap inwards with a copper hammer, some do requre a bit of a wallop to get them to move, undo through nuts and bolts on joint in question and swing hub outwards by tapping hub where the joint goes through if needed, undo ball pin nut, using the good old two pounder a few sharp wacks on the pin eye and out she pops. It is definately worth doing both joints at the same time as checking for play without taking the tension of first is nigh on immpossible and I have seen 900`s pass their mot with ball joints that are on the point of failure. Reassembley is the reverse of what you have done [quote from Haynes manual]. HTH Tom, Saabtech.
