I totally agree with John, drop the axle (not too difficult) then I used oxy/acetylene welding torch to burn out the old rubber and to cave in the outer case, (someone will probably tell me I shouldn't do this!) then pulled the new bushes in with a lenght of m12 threaded bar, (high tensile if you can get it). Check the voids are at the top and bottom! The first side I did was easy but the second wouldn't go the last 4mm so ended up man handling the axle to the press. Hope this helps. Alan
