Can you be more specific on exactly which rear suspension components have worn bushes?Mates got an `04 est on 95k but haven`t been under it,so don`t know how much the estate rear suspension differs from the saloon?With the latter,the rear trailing arm bushes can be removed using a tool which unfortunately costs over £100!If that is the problem then do you have access to a press?Are you handy with fabrication?If so you could knock up a tool for next to nothing.
