My Manual Transmission sounds like an idling diesel

[96firephoenix]

I've observed this condition in neutral, parked. No way to observe while driving due to wind/engine/road noise.

Clutch is pressed (disengaged) from about 0:09 to 0:12 and 0:20 to 0:22

Edit to clarify: this is a 2002 Explorer 4.0 V6 5 speed manual with 4x4

This is making noise in the opposite pattern of a bad throwout bearing.

One of my co-workers suggested that it may be the input bearing... any thoughts or experience in the matter?

Also, Diesel Idle for reference

Indeed it sounds like a bad bearing on the input shaft or possibly the countershaft.

Thanks...I did spot a heat shield that has fallen off the exhaust and is almost touching the trans. I'll straighten it out before I get into the tranny, as this wouldn't change with the clutch in or out, I would think.
