Just take the whole strut and hub off the car. Much easier than faffing around making home made tools or using the dodgy bottle jack technique. I changed for VWR springs last month. I'd advise getting new top mount bolts (one of mine stripped the top mount so had to be cut out) and new hub bolts if you are going to remove the hub. Hub bolts were £3.50ish and the top mount bolts about 30p each iirc. I reckon I could strip the hub off the golf in about 30 minutes now.
