To take the shaft out you need to undo the 24mm nut in the middle of the hub(think thats what size it is) then the pinch bolt on the track control arm and push the t.c.a down so you release the hub from it then pull the end of the shaft out of the hub then once you have the hub end of the shaft out all you need to do to get it out the gearbox is to give it a good hard pull and it should pop out (sometimes they can be a fucker to get out and you may need to use a crow bar ) bewarned when you pull the gearbox end of the shaft out gearbox oil will piss out of the driveshaft hole.
