Front wishbone rear bush fitting - easy!
Been wondering about this myself so I had a go tonight and was surprised by how easy it is...
First, clamp the wishbone in a vice (I'm sure you can do this on the car but I'm refurbing some wishbones so the vice was the way to go).
With a 9mm drill, drill through the rubber. You'll cut into the aluminium housing of the bush...

Use the drill to thin the housing some more, being careful not to damage the wishbone - you don't need to go right through, just thin it.
Then hammer a screwdriver between the bush housing and the wishbone...

This should be enough to loosen the bush and it will just hammer - out...

Use a big socket or a suitable bit of tube to isolate one side of the bush while pressing it in with a vice. You can clamp directly onto the other side of the bush as it'll compress enough to push the whole thing in...

And... you're done!
Easy as! took 20 minutes to do both bushes :)
Any questions - just ask.
