remove exhaust, remove struts/knuckles, remove the 4 bolts that hold it in. Put a jack under it so it doesn't fall on your head

It's not that bad of a job. Remove the control arms after you get the old subframe out. I found it easier to loosen the bolts that way. And make sure when you reassemble it that you leave the control arm bolts loose. You have to have the car on the ground to torque the control arm bolts
