Right so im putting a ZS axle on my mk3, thought may as well uprate the bushes so got some powerflex ones. Done them tonight and took some pics. My axle was off the car anyway but its pretty easy to remove it. Just unbolt stuff attached to it and remove! Just use common sense. Use axle stands and be safe. mk4/5 axle bushes are slightly different but same principle.
My way of getting car higher to work underneath!
Tools needed:
-hammers
-screwdriver for prising things
-powerfull drill with large ish drill bit
-tenon saw? one with removable blade (must be removable, you will see why)
Right, now to remove the old bush, remove the bracket surrounding it. (pretty obvious but there are some people out there). Get your powerfull drill and basically drill out all the rubber bit. so its possible to use your hammer
to smash out the middle bit. First one took me a while but the second one i got down to an art and it was out in no time.Once done you should have a roundish hole. Get the saw with removable blade. Put blade in the hole and attach it all together and saw. Not for to long but enuff so it splits the outer metal part of the bush. Once thats done you can hammer a screw driver down the side so it starts collapsing on itself. Now hammer out with a hammer. Hopefully this picture will explain a little.
Now you should have a hole like so:
Now get your new hard bush and grease it up; smear it round a bit really...
Install:
And push in:
No need for a press at all. If needed use a rubber mallet.
Now get the metal sleeve it bit of grease on this too, and shove it in:
Install bracket.
Repeat for other bush.
Now reinstall to car and your done.
The grease, (comes with bushes but im sure its copper grease?) is important as it will stop it squeeking.
Hope this helps someone in need.
Random one of george:
Tenon saws are square used primarily for wood cutting. 
Awesome stuff!
