I was jumping onto a freeway entrance ramp, getting to the end of the ramp doing about 55 miles an hour, This large, long black object just chillin on the freeway. I hit it before I had time to react, it went under my car, made a loud clink on the passenger side wheel, the car was entirely unaffected by it... Made no noises, so today im heading home from saginaw, and I go to a gradual turn on the freeway and I hear an intermediant Squeaking noise... sounded like an old gate hinge on a fence being opened and closed over and over again. Did it a couple of times at a couple of volumes, only if I turned to the right... and it hasnt done it since... Can anybody shed some light on the subject?
