What is this thing?

[ProfessorX5]

Any clues what this might be?

Blurry picture, any description of it?

Something under the bumper?

[ProfessorX5]

Yeah, it seems to be some kind of box-like thing that must have held something. I'll snap a better shot in a bit.

Man you really gotta stop drinking in the mornings and focus your iphone LOL

Cut out for 2" receiver hitch. You start some strange threads dude.

If you indeed talking about that oval shapped punchout with the grab handle, just reach down with your fingers and pull it out.

You will see the trailer hitch mounting area, where you too can install the $2500 trailer 2" hitch if you are so inclined. See threads for that project.

Now, if you are referring to the shaps under the vehicle, that looks like a school crossing guard and stop sign to me.....

Mounting support for alien spaceship trailer hitch, goes with the alien twins fetus window sticker.

I think Molder and Scully were POs of your X. Have you checked for protoplasmic goo under the rear seats?

[X5SND]

Are those your heat shields hanging down on either side of the battery box?

[motordavid]

I think it's the rear tow hook attachment point, if the area of question is the oval with the horizontal 'hole'...

The OP ought to skip some potential mods and save a few bucks for a camera, or look on the web for free Photo 101 course.
