When I drive faster than 45 miles per hour my jeep starts to buck or*****. I hear a clunking sound that seems to be coming from the drive train or transmission.

The noise is most likely from the engine bucking. Start by checking fuel pump pressure, check for tune up, and VERY common on these vehicles, check for vacuum leaks.
