yes a real bad job to do -need axle out heavy duty press -to press torsion bar out and oxy/acetelyne to heat up same,then you need to press bush from arm-to do this i used to weld a substantial washer on end of bush sleeve to give something to press against!if you do one side at a time you can set position of arm same as opposite side.outer part of bush can be removed with hammer and drift.make sure all splines on torsion bar are cleaned and slide into mating components easily [in case susp height needs adjusting. good luck!
