Had mine done last month, used an independent garage as the price was good, they did it in under an hour, I supplied the kit from VW which was about £22, new clips etc, they had no trouble, 2 ways of doing it i think though from the ball joint!, either undo the 3 bolts taking the ball joint out with it or seperate it!. (they seperated it) i was a bit dubious as sometimes when you seperate it you can then split the ball joint itself, giving you another bit of grease leaking out.
