I am looking to replace the control arm bushes on my 2007 Roomster 3 1.9TDi as this is the second time they have failed in 4 years. I'd like to upgrade them to something sturdier and I'd welcome anyone's advice who has done this already. If I am buying off the internet what do i need to purchase?

Have a search through the Fabia forums and technical guides(Fabia wishbone bush replacement DIY Guide) you should find all you need including pictures .

Sorry I cant help more but I know there a lot in the Fabia section which share the front suspensions as thr ROOMSTER or so I understand.
