heat the steel up with a torch and not the rubber makes the rubber soft then hit them out with a hammer. bit of flame and smoke, very easy to do

what ever you do dont heat up the new bushes as if your not carefull you will melt them.Infact when fitting them you could heat the hole in the subframe but its not needed.You need to press them in,or use the tool.Or use some studding and washers to pull it in.

If you don't have the tool then you need to remove the subframe from both ends.

Be easy to do mate, just have someone to help you out. Do the rear mounts too while you're at it, and paint it all up. That's what i did.

Yet to try it myself, but old skool 2002s idea of using a hole saw sounds the way to get the old bushes out.

i think it was danthe that came up with that idea,very good idea.I just heat them until the centre metal sleeve drops out then put a hacksaw into the centre and saw in 2 places then pry it out.

if you melt some types of rubber you can produce it and its really nasty stuff, touch it with bear skin and ive heard of people having to have their fingers cut off. Its mostly old engine seals I belive, im quite sure that this type of rubber isnt used on bushes.

I removed my beam, stripped it down then used a bottle jack in a door frame and some wood to form a make-shift press. (I'm sorting a picture hosting thing soon so I'll re-post a pic later)

Worked a treat! I had to apply the full load and some heat to get old ones out. Hairspray is a good lubricat to get the new ones in.

I put Polyflex bushes into my iS. MUCH easier to fit but I'd urge 90% of road users to fit rubber bushes, I'm going to on my S50 Powered 325i.

Hydroflouric acid is evil.. Gets onto skin, soaks in with little damage and dissolves bones and organs. Yummy. 8O . You wont produce it burning your bushes though.
