Metal Grinding when letting off clutch

I have a 2009 4 cylinder manual. When i am coming to a stop I put the truck in 2nd then into neutral to coast to the stop. When i let off the clutch peddle in nuetral it makes a metal grinding noise. Its only at slow speeds, it doesn't happen every time, but it is becoming more frequent. Any ideas of what it might be.

 

TO bearing im gonna say, it spinning on the tranny shaft TEHE.. mind you i think thats just a 6m problem

 

This is a common issue for the RC's, the consesus seems to be that it's due to excessive play in the driveshaft's slip yoke. Here's more info . . .
