Today I replaced my rear springs following the instructions provided by Coxy1. I've bombined all his seperate PDF parts into 1 big one. Alfa Romeo 159 Spring Replace Manual
I have the luck that my car has the damper bolt in the wrong way. Since I din't have a spare bolt I needed to remove the spring without removing the damper. So this is an extra on top of the "how to" Coxy1 write.
(in the attachment are the same pics).
Here we see the lucky bolt.
Crack the bolt, and turn in ~3 times. This creates the little room we need later on.
(at this point, you should have done all instuctions from Coxy1 up to point 9. I didn't remove the bolts at point 10 yet, this causes the spring to move when compressing the spring in a late stadium. Personal choice.)
Jack up the subframe so we do not have to turn the spring compressor manual as much.
Compress the spring as shown in the picture below. This is the minimum you need to compress to get the damper out of the hole at the top. To get the damper out of the whole it would be easy if you have someone standing on the subframe. Ofcourse you need to remove the jack below the subframe first. While he is kinda jumping on it, you can pull the spring with the damper inside out of the hole.
Since we loosened the big nut of the damper a little, we should be able to move the damper a little towards you.
Now we have enough room to do things. Next step, remove the nut from the damper. Keep the center from moving using a small wrench.
You can compress the demper by pushing down. Keep it down (it slowly rises). Now you have created enough room between the top of the damper and wheelarch, lift the spring out.
Resulting in a lonely damper.
Compress your new spring, and reverse the process.
I've damaged my new springs a little with the compressor. Since I don't want to repeat this process in the future, I have painted the little damaged parts with Hammerite, luckily I had some Hammerite that was the same colour as the new Eibach spring. In the pic below you can see the damages.
Don't forget to tighten the damper nut at the bottom!!
