I have just done mine - I knew it would be a nasty job - and it was!
I read the forums so was armed with lots of ideas -
Removing the bolts:
On the drivers side I have to lower the exaust to get the bolt out, on the passenger side is much easier - they were so tight and rusty ended up virtually destroying them. I ordered two new ones from main dealer about £7.00
Getting the old bushes out:
I drilled out all the rubber and plastic and then pulled out the alloy centre bit. I then used a hacksaw to cut through the metal edges of the bush. Then a large screwdriver to split the metal bits and they fell out. Cleaned up the mounts with a small file and steel wire to remove all the rust etc.
Getting the new ones in:
I decided to use standard replacement bushes (rather that poly bushes) and thought they would be easy - they were not. Without a suitable tool, you will never get then in. I bought a simple tool of ebay (about £32 ) which worked great - but even with this you need to get the bush completely straight and well lubricated with copper ease etc or it won't go in and even then it is a VERY tight fit. REMEMBER TO ALIGN THE BUSH CORRECTLY AS PER OTHER GUIDES ON THIS FORUM
All done now :grin: and hope I don't have to do then again.
Good luck
