Thanks for all input about eratic steering going to have a go at replacing and getting local garage to press bearings in. Im guessing it should look like this; Guessing remove wheels, calipers, discs, hub nut then swivel hub do I need any special toys to do this ( hub nut size ?). when looking at weekend the torx screw on one disc looked mullered any tips for removing other than drilling out.
As for the torx screw try and knock it undone with a centre punch, done this several times. As for the hub nut just a hub socket mate, I suggest either using an impact gun, or cracking it off with the centre cap removed in centre of wheel with weight of the car if you get me drift
