I have a 2001 civic and when I start driving in the morning I hear Metal
sounding Ca-Chunk, It happens after about 1000 ft or so. Also I notice
when I am driving less than 10 MPH and idol forward I can hear a repeated
Metal sounding Thump. Just wondering if anyone may know what this may be
before I take it in for service and get hosed since I have no idea what it
is. Is almost sounds like when you run over a rock and it comes up and hits
the underside of the car.

Thanks.
