2000 Sienna LE Drivers SIde Sliding Door

Hello-
I love this van but just recently it sounds like there is a little rattle coming from the door. It is not a power door fyi. Has anyone had this issue. I was wondering if it was a loose bracket or something more serious? Any input would be greatly appreciated.

you can adjust the rubber stops to get the door to sit tighter... i read up on this in this forumn... suggest you search it...
