You put a piece of wood between centre of a old bush and the car. You jack the rear beam untill old bush goes out. polybushed go in the same way.
One of simplest jobs. Be carefull with large bolts through the bush - it's easy to strip the thread in the bodyshell.
I started to re-assemble the rear beam tonight and by just jacking up the beam I can't seem to get the long bolt that goes through the bush to bite!!! - Is there a certain way I should be jacking it up????
