Loosen the strut tops 1st (If you cannot do this get a garage to crack them off with a impact gun and then to tighten them up finger tight)
Loosen all wheel nuts
Jack up front of car and remove both front wheels
Behinde the wheels you will see 2 x 19mm nuts and bolts holding the bottom of the suspension strut to the wheel hub, remove these 4 bolts
Finish undoing the strut tops and they should just fall out.

Open your boot and loosen the tops of the rear struts

Gently lower the swing arm via the jack until you can pull springs out
