Subframe bushing replacement S40 2007

[wool]

Which is a better way to go when replacing the front subframe bushings Remove the sub frame or fight the old bushing out of the frame? I've seen a few instructionals of removing bushings on non s40 which show a lot of cutting and hammering. I used to go this route when removing lower control arms on my older BMW's I would prefer not to go thru that again. How difficult is it to drop the entire subframe. What components are involved Which would be the best way to go?
Thanks for your help. Wool
