Underbody Ticking...
 

Just out of curiousity, I was wondering what was causing the ticking under the body of my xA (as well as most other cars) when I get out after driving for awhile. I know my mother's saturn does this, and my old mercury did this, also. I've been told it's normal, but no one has ever actually told me what it is. Do you guys know?

yes, my tc does that also. however, only when i back out of my driveway and afer that i dont notice or hear it

I don't know, never actually thought about it, I used to think it was just road grit falling off(?????) but now I'm pretty sure its about the metal cooling.

yea i thought that also...because my driveway is gravel and rock and i figured out it was something else clicking

some thing to do with metel cooling and contracting

any of you have electric heat in your house? its the metal cooling and contracting, namely the heat sheilds around the exhaust that are made from thin sheet metal...get really hot...and start cooling fairly quick

if its a ford i always say, "see you can hear it rusting!"

ROTFLMAO

Its the metal contracting, but i do like the Ford rusting answer.
