Disco 4 suspension bushes

[Thevet]

My 60k Disco 4 needs new suspension bushes on the front, I believe main dealers will fit complete new arms at a large cost, has anyone tried replacing the bushes themselves using polybush or similar? Any comments and guides gratefully received

As far as I am aware, the local main dealer Taggarts will replace the whole assembly, could still be covered by warranty in which case I might put it to them but they are uninspiring to say the least. The diagnosis of knackered bushes was given by a local specialist who just replaced a front strut that was leaking air on the car. Are the arms and bushes easily removed/replaced?
