[Vwdiesel] When it rains...

[Val Christian]

OK, like I didn't have at least one problem emerging on my TDI.  Now I 
need some group wisdom.

Symptoms: Growling, as in bearing, going down the road
-appears to disappear without forward motion
-clutch engages and disengages smoothly
-clutch pedal has vibration on it, and does not have the "free play" it 
used to
-had one instance on a 3-4 shift where the  transmission appeared to be not completely synced.  That happened several days ago, and I attributed it to me 
not noticing something, or doing something right (distraction)

I'm thinking release bearing or bearing/fork  What are you thinking?

Ideas?
