Yes you are right you need a special tool for the oem bushes but my understanding is that the poly bushes didn't need a special tool? You are probably right though, will be a lot easier with a ramp lift anyway. The guy at local garage said he may be able to borrow the tool anyway.

I've fitted Powerflex bushes on a couple of Peugeots - they're brilliant for replacing ones which would normally need the part taking out and the new bush putting in with a press.

Also handling was slightly better too, but that might have just been because I'd replaced a 10 year old part!

Actually someone with a gorilla grip may be able to push them by hand, but the vice (I (ab)used my woodworker vice, but if you need larger surface area two bits of wood plus a normal vice is just as good) is plenty, it pops in no time. I made sure the inside of the arm was clean and smooth, no burrs. Just slather the bush with the silicone grease so it won't get damaged.
