It is there with the clutch pedal pressed in and let out. The transmission shifts/drives fine and there were no metal flakes in the fluid when I changed it. The driveshaft was cut and balanced. What could this be?
Some things that I am thinking... input shaft bearing is bad, TO bearing is adjusted to rest on the fingers, TO fork ends should be round (welded flat because I thought this was wear), or the rear U-joint needs to be greased (I packed it when I put it back on but never shot it on the zert)... any thoughts? | | |

If it is any trans. brg. it will be much louder in all gears except 4th. I wouldn,t suspect a u-joint either. What about wheel brgs. How about diff. brgs. Did you change the rear end at the same time. The t.O. brg adjustment is easy to check & if it not contacting the clutch fingers it wouldn,t make any noise.

I will do some checking this weekend on the TO bearing but it sounds like this is probably the input shaft bearing. | | |

I had to do some extra hammering once after making that change on another truck. Now I have a muncie and they all are noisy. | | |
