Can't stop extended cab doors rattling!

[jwink]

The doors on my truck rattle like crazy even when you hit the smallest of bumps, it is really driving me crazy! This is probably the thing I hate the most about the truck this and the rattling in my clutch or pressure plate, but that's for another day. is there any tips or tricks to get these things from rattling so much, a friend has a 99.5 with about 300,000 with about half of those in the pasture and his don't rattle at all. Do i need to put in new weather stripping or shims or is there a way to tighten the doors up?

the rattle @ the clutch is most likely the throw out bearing, as for the doors i would start by checking out the seals or door latchs
