Just installed two new rear links and was wondering how long they should last. The rattle noise from the old ones was driving me nuts. They are made out of some kind of solid plastic material. When I compared the old with the new there appeared to be not a lot of difference. Are there any other 406 owners out there that find they have to replace them on a regular basic or just put up with that bloody annoying rattle. The rattle is now gone, hopefully for a long time.
