? Noise under right side floor

I get a banging noise under the passenger side floor, you can feel it sitting on passenger side, it happens mostly at low speeds, and when turning sharp corners, but I have not narrow it down any further.
Any ideas or suggestions?

What year?

1998 S-10 4wd

I got funny clunk/banging noises from mine a while back, at low speeds (like crawling) when turning sharp. found out that those aluminum guard plates under the trany and front of the engine were the culprit. no matter how tight I put them (torx bolts) the noise would come back. so I took them off - I don't 4x4 in the woods anyways so what the heck. noise gone. check it out, look for the marks of movement at the bolts and plates.

Hood washer are the culprit in most cases and was a release from the GM service department.
