Fabia Rear Wishbone Bushes

[nbramwel]

My son has a 2008 Fabia 1.9 diesel.  I would be grateful is someone could set out the procedure for changing these bushes please, particularly getting the old ones out using the special tool designed for this.  How do we remove the wishbone in the first place and anything we need to be particularly aware of.  We are thinking of installing Powerflex bushes as the Skoda ones don't seem to last very long.  Many thanks.
