the trailing arm bushes (one the beam is off) can either be pressed out (again IIRC mine took about 30 tonnes of pressure on a hydrulic prss to shift them, the otherway is to get the end of the arm hot with the 'blue saw' and use a void bush puller, i don tlike this way as much as it may weaken the metal with the heat, but you can get away with not having to disconnect all the cables and half shafts.
