I looked this up in the w/s manual and this is a fair old job .
It's shown as removal of shock absorber, as the spring comes off with it.
Unless someone knows a better way you have to remove the drive shaft, matchmarking it with paint [not punch marks]
for correct refiitting.
Spring compressor/s and hexagonal socket for inner coupling on drive shaft etc. needed.
Rear seat cushion out,parcel tray,roof side garnish out [bit with rear courtesy light in], right and left scuff plates off,brake caliper off.
Not a job for a cold day outside!.....can you put it off until summer!!
