I have a 4.3 5 speed and when I'm in low rpm something under the truck rattles. But when I drop the gear or once I've reached a certain rpm(about 2500) it stops. What could it be?

I appreciate the help thanx.

How low of RPM? My old volvo rattled when you lugged the engine... If not that, then it could be alot of different things. Where under the truck?

I'm thinkin at around 2000 and it comes from somewhere in the middle of the truck or towards the back undercarriage.
