Door question. Bouncing up?

[MDOC111]

I've had my 96 Suburban for 6 months now and I've got a question. When going down rough roads, where the truck will vibrate like gravel roads, it feels like the drivers side door will bounce up occasionally. The pins and bushings look like they are fairly new. Is there something else that I should check or replace? Thanks for your time and help!

Ok. Thanks! I will replace it and see what happens.
