Backing out of my garage this morning, with the XM radio playing, I heard some distortion (I thought) while rolling slowly. Turned the radio down and it was a loud grinding, scratching noise.
I suddenly remembered that I took the Swagman bike carrier off earlier in the morning.
Had I left it on the floor behind the Civic?
Got out and looked under the car...no Swagman wedged underneath. The car rolls very easily, so I pushed it back and forth a couple times and the sound was terrible.
Something rubbing/scraping....it sounded like I was dragging my whole exhaust system.
A light bulb turned on and I remembered the same happening with my Prelude a year or so ago.
A stone wedged in my front disc brake dust cover.
Drove it around my circle driveway at a fast pace once and it worked/bounced it's way out.
Maybe it's a common thing..but it's only the second time I've had it happen.
