My '05 Suburban makes a sound at the front passenger floor board whenever the vehicle goes around a corner. It sounds like a ball rolling back and forth. My daughter claims she can feel something moving, although I do not. Inspection from underneath does not show anything and the dealer claims he cannot find the problem or duplicate the symptomes.

Suggestion? [/align]

 

Welcome to the Forum,
I would take the service advisor and/or tech for a ride and make him/her sit where your daughter sits and try to duplicate it that way.
