As I found literally nothing on the internet regarding this subject, I decided to take photos while I replaced mine.

First, Jack up the car and remove the wheel:


Remember to put a jackstand, I put mine undir the rear subframe, then lover the jack.

Next jack under the rear till there is no stress on the strut and remove the lower bolt.


Next you need to remove the rear upper wishbone, first release the wiring and brake pipe for the holders.


Loosen the nut and the bolt that holds the wishbone.



Then the upper rear wishbone can be removed.

Time to remove the spring. To remove it since there is no space for spring clamps, I jacked under the hole thing till the spring was as compressed as i could get it, then chained it to holt it like that. That way when i released the jack the spring was a bit looser, and with a crowbar, got it out.


Then to take the chains off the old spring, I used spring clamps.


Then did the whole thing backwards, for the installation of the new spring.
