We had a mondeo estate in for those bushes last week, got the bushes from our local factor and in the box there was a leaflet trying to get us to buy the tool for the job. When i was told it was 500+ pounds we had to find another solution,i found an old 7 series rear bush tool that we dont use anymore and we just removed the trailing arm and pressed them in/out quite easily using part of the tool. Took two people with one holding the arm and one guiding the bush and operating the press but it was fairly easy.

This was the old 7 series kit,we used the big gold coloured piece
