So I was involved in a very low speed parking lot mishap. The picture below is the result.
How hard is it to remount the bumper? I'm mainly concerned about the alignment/gap, it's minor but you can definitely tell its not straight you'll see it slightly misaligned. I don't know how it's attached, but to me the bumper seems to be un-deformed and it feels like it just needs to remount properly and I'll be a happy camper.

What would a body shop charge for this? Just want the bumper to be flush with the body, don't care so much about the scratches and paint marks.

 

It's very easy if those tabs underneath the fender aren't rip. Just lift your bumper to push it in.

 

I had samething and same spot and I couldnt fix. I think the bracket under the headlight is loosen. this part is attached to that bracket.

 

Happened to me, make sure the tabs aren't folded down, and are properly fitting into the headlight bracket. Also make sure the wheel liner and under plastics are layered correctly.

 

Requires dismounting the bumper, re-aligning all the tabs on the body and the bumper and remounting. If any tabs are broken then a little more work to replace, repair, weld may be needed.

 

This should be something that you can figure out once you take the bumper cover off. It will be hard to tell until you do that but it doesn't look that much of a chore

 

I'm no mechanic but I found removing and re-mounting my bumper when I changed my fogs to HID was a huge pita... There are a lot of different screws and for me it was hard to figure out underneath the front lips what goes first because there's the lip, then the plastic underbody piece to screw in.

My advice would be if you do take it off yourself, pay really close attention to what screws came from where and the placement of things particularly under the front lip.

Also, not sure if I'm the only one with this problem, but since I remounted mine the very top corners of the bumper in the wheel well seem to lift off the body of the car and don't sit flush.

 

I have the same thing
My brackets are broken so I couldn't fix it.

 

Looks like your headliights moved slightly if so you need to fix them so the bumper aligns correctly to the lower headlight braket.

 

That's how my bumper looked. It ended up being a broken bumper tab right behind that gap. $20 for a new one at Sewell.
