the grille doesn't even have to be completely removed, it can stay attached to the cover. just remove all the clips along the top of the grille (along with the 2 on either side holding the bumper) then you need to loosen the 2 sides.
turn the wheel right to access the left side bolts & turn left for the right side bolts..
for each side, remove the few phillips screws & then the rear most lower 10mm head bolt, then pull back the liner, release & detach the wheel opening molding from the bumper. there are tabs that you just grab from behind & squeeze/twist while pulling the molding out... once you release a few you'll see how they work. once the molding is detached all the way up past the bumper fender seam & the fender liner is pulled back you have to remove 2 10mm bolts that are at the seam between the fender & the bumper. these 2 bolts are the hardest part of the whole job. they go in from the top behind the lower front edge of the fender... feel around in there & you'll see them, don't be afraid to really flex & fold over the fender liner to get access.
once these bolts are removed from both sides gently pull the corner of bumper out & slightly downward, don't pull too hard because there are 2 clips under the headlight also holding the bumper. you need to while pulling with a little force, slide a long thin screwdriver in the opening between the headlight & the bumper & pry up on the edge of this clip, it will pop & release, allowing the bumper to come out even more, but then there is one more of these clips to release & that's it, the bumper is off...
it's a good idea to have a milk crate or similar close by so when you hinge the bumper out you don't let it just hang, a milk crate or similar in the center is a good place to rest the licence plate bracket to kind of hold the bumper up a little & not hang so hard.

also when doing one side it's still best to remove both side bolts & hinge the whole top of the cover out, trying to just do one side bolts & stretching the cover takes a lot of flexing & might do damage, done right there is much less risk of damaging anything, I'd always take both sides of the bumper released even if just doing one side headlight
