Hey guys..

Its been a long time, haven't been around the forums in a couple of years but I need some help...

I still have my '06 MC 3500, and when you close the driver side rear door (only), moments later a 'thump' occurs that is Omni-present, and I can't for the life of me figure out where it's coming from. I thought for the longest time my eldest child was mocking me and kicking the door panel when we were in the truck, but it does it when she's no where near the truck...

Any thoughts? I'm not even sure what the heck to search for, I did MC Rear Door, Door Pop, Rear Door Pop... couldn't find much other than cleaning pop spills off doors.. :/

Thanks guys!

 

Check hinges, loose or maybe have some play.
