Fronts come out pretty easy on the premise that you have some big sockets and a press/vice. Putting the new rear bush in can be a bit awkward, and a lot of the time it does look like the bush is gonna pop out sideways.
Rears are a bit more of a pain. But if you drill all the rubber out, the centre should pop out. Then you can chisel the outside out or run a hacksaw through it to split the outer. New rears just slide straight in.
If you’re anywhere near Stoke. I don’t mind pressing the new ones in your front arms if you strip them all down first.
