I had a cover on the plates that would not come off so that I could put my plate sticker. So I had to take off my bumper, to take of my plates, because the screws would just spin. Once I removed the bumper I saw the problem, and just like I thought the metal tab that the screws screwed into where rusted on to the screws. Also the plastic tabs that were part of the bumper broke when I tried unscrewing the first time, oops.... here are some pics. So I'll have to figure out what to do next year to fix that problem.

 

diy section?

i dunno. this in informative in that you tell us a problem exists and you fixed it. not much more. mind telling us how took off the rear bumper?

 

Well the problem still there I will fix it next year with some fiberglass or something lol. The bumper wasn't to hard I guess time consuming a little bit.

-Disconnect the negative battery cable
-Remove 4 fasteners of the trunk end trim
-Remove 4 trunk side trim fasteners (do not need to remove all fasteners, if you do it just gives you more room to work with)
-Remove rear combination lights
-Do not have to remove rear bumper gaurd off
-Remove screws and fasteners inside the rear of the wheel well
-Detach/Remove bumper by pulling both driver and passenger bumper sides outward and back, and pull back on the center rear of bumper

-Install in reverse order
