A good drill to drill out the rubber, a decent hacksaw to cut a a peice of the alloy cage out of the axle then crush the alloy together and chisel it out.
First time doing it you will take on a drive with basis tools around 3-4hours, second time would take about hour and 1/2.
I would buy polybushes to replace them as they dont need pressing in (I used the ones from PSI tuning, the bush fits in nicely and a metal sleeve crushes the bush in tight)
