I have an answer from Anze Suspension :
Hello xx
My name is xx and I work for Multimatic dealing with a lot of these requests. I unfortunately have bad news for you… Due to how these dampers were designed, the top cover is crimped to the body, so it is unable to be taken apart without destroying the damper. This unfortunately means there is no way to rebuild them without ruining the damper.
Sorry for the bad news, if it were up to me there would be some sort of solution but at the moment there isn’t really one. Sorry again for the bad news, please let me know if you have any further questions.
Thanks!
So I guess it's clear they can't be rebuilt... Too bad.
Thanks everyone for the input
