After I washed all the mud off...I found

[HummBebe]

A couple of owies on Hummbeebe. No big deal, but the rear bumper has a few scuffs, license plate frame was totally tweaked, and I noticed, when I am taking the kids to school in the morning, and I am making some tight turns in the parking lot, there are some clicking sounds coming from the front end.

Can anyone tell me what the clicking sounds might be?
And, is there any way to fix/disguise the plastic bumper?
Plate frame....I already bought some new ones

Thanks
