vibration sound in door

[s mxwl]

I have a 2009 Envoy SLT. There seems to be a vibration sound in passenger door when going over small bumps but not allways. The door was slammed hard prior to hearing noise. What would I look for ?

Being a 2009, your best bet is to bring it back to the dealer. Take advantage of the warranty that you have with the Envoy.

Good luck and keep us posted, you should still be covered by the 3 year 36,000 mile bumper to bumper warranty, under normal circumstances.
