Wow......that is a sickening feeling when that happens. I was on my way to the GT school in March and came around a bend only at about 75 in pitch black darkness and right in the middle of the road was a BIG rock. Nothing I could do. WHAM......and I was sure the front splitter was gone, but when I pulled over nothing. Looked at the rear, nothing. I think it must have been mostly mud around a smaller rock. I was sweating it.
At my next oil change Kendall discovered a small hole in the belly pan. I repaired it......yours I would replace also.
