Loud Clunk

[fanelle]

I have a 2000 s10 XR2 and when it rains or when it's wet, i get a loud clunk on the right hand side of the truck somewhere around the middle to back when i hit bumps. Sounds like something is loose. I crawled under the truck but see nothing. If it's dry the clunk is gone, it only happeneds when it is raining.

Could it be the torsion bars? if so how. COuld it be where the leaf springs mount?

I'm lost and am about to run this piece or S$%^ into a tree. I've been a Chevy guy my whole life but am loosing faith. The truck is starting to nickel dime me to death.

Help,
