My car has some "click click" sound underneath when I drive very slow (20km/hr) in the rough road or even go over the bumper. when u go over 30km/hr or even get out of the rough road then no sound anymore. I went to dealer and have them to check it out. First time they thought was Suspension problem so they just tight the front and rear suspensive up. But it is still the same sound like that. So does anybody know what happen or what should I do?

 

Could it be a rock or nail in a tire?

 

The sound is really loud. Sound like something is loosing (crack crack)
Tires are ok... Sound is from underneath between passenger side and shifts...

Just a long shot for your noise problem.....I had much the same and found it was the loose spare tyre......found the securing bolt was a few turns loose..

if its at specific intervals like "click...........click.............click...."
its your CAT cooling off.
nothing to worry about.

 

could it be the diff?

 

You would hear it at low rpm's in every gear and on a straight road .
