It's piss easy mate. Just pulled mine back out so I can clean em up and remove helper springs before car goes back on the road. Took maybe an hourish by myself.
Rears:
1. Remove back seat(2 12mm bolts at the base either side, pull up and out then 2 on either corner below the top half)
2. Remove parcel shelf, pulls up and out.
3. Undo strut top nuts(2 12mm bolts either side under the parcel shelf)
4. Loosen off wheel nuts, jack up car under diff. Lower car onto stands.
5. Crack the lower strut nuts, 17mm. Will most likely require a decent length breaker or a breaker with a length of pipe over the end especially if they've never been removed before.
6. Pull bottom mount off hub(May need a screwdriver etc between hub and shock if it's tight). Shock will then drop down.
7. Install in reverse order.
Fronts
1. Open bonnet, undo strut top nuts, (2x 14mm either side)
2. Loosen wheel nuts, jack car up at front, (I usually use the engine crossmember or if the cars too low the tow hooks under the front bar) Lower onto stands.
3. Crack lower nuts, 17mm again. Will generally require similar force to the rears.
4. Loosen off same as rears.
5. Assemble in reverse order.
