This is just a simple write up for people who doesn't know how to remove the bumper on their 4th Gen Subaru Legacy.
My car is a 2005 Subaru Legacy GT, Bumper removal DIY (these are just keywords for searching...)
First of all, un-clip the 4 tabs that are behind the grill
Then remove the 2 bolts that are on both side of the grill
Then there are 6? 8? pop it tabs that are on the underside, along the edge of the bumper, remove all of them. Just get under the car and you'll see them. Think where you'd add a front lip, and just look in those area.
Now onto the fender well, pull on the fender liner, and you'll be able to see another pop it tab hidden.
Now before you pull the entire bumper skin off, disconnect the fog light wiring
Simple enough right?
I don't have a 08+ Legacy, thus I don't know if they are different or not.
