fit the new chassis bush to the chassis and loosely tighten the three bolts/nuts Slide the arm into the chassis bush and then offer it up to the axle bracket. Seeing as the polybushes were wider than before, I had to prise apart the bracket slightly. It took a bit of effort but finally I could get the bolt back through the bush. Tighten the axle bolt to 176Nm . The way the bushes have ended up is looking like they're slightly bulging. Time will tell their effectiveness and longevity. Tighten up the three bolts holding the chassis bush to the chassis and then the main 30mm nyloc nut to 176Nm . Use lots of copper grease for the next time it all comes apart! The handling of the vehicle now feels a lot better. It's a less jarring experience going over bumps and potholes. Time will tell as to how effective the polybushes are, but if they had to be replaced again i'd feel a lot better about it knowing that I wouldn't have to hacksaw, hammer and press my way for a couple of hours to removing the existing bush.
