How hard is it to remove the rear bumper and than put it back on correctly and aligned properly?

I'm asking because the dealer scratched my rear bumper and they are replacing it. I'm afraid they might not put it on correctly.

 

I have the same question as some a-hole hit my bumper in a parking lot and broke the side clips that connect to the right rear fender. I have reviewed the instructions to remove the bumper that come with the underbody spoiler and read parking assist, but they seem to lack some detail.

I believe that many people on this board have removed theirs. if you have any thoughts, let us know.

 

I would trust the dealer and if you don't like the way they do it make them do it over untill you like it

 

I haven't removed mine, but looking at the car and at the Service Manual, it seems like a very easy operation.
