Just a note on Ken's comments, it is entirely correct for all grey (and red, blue and black) powered cars. It may save some unwary person from having to dismantle their engine....
Using a spiggot shaft or other close fitting drift works fine on the older cars. A hydraulic effect occurs as the grease forces the bush out. This is fine on all cars to my knowledge up until the mid nineties.
With newer cars, some have a hollow crank with a welsh plug that goes into the other end. When you try this method the welch plug pops out, thus requiring the engine to be dismantled. Check before merrily pounding away.
I would hate to see someone caught out in this way, requiring the engine to be partially dismantled.
