Looking to see if anyone can shed more light on an issue that began yesterday with my Daily Feroza running an SR

After getting in the car after work I noticed a really odd grinding feeling (hard to described accurately, but its not like a crunch when you don't clutch all the way or miss a gear)
This feeling is felt through the clutch pedal when releasing and also through the shifter when changing fear, most prominent when going from 1st - 2nd - 3rd and a little in 4th, only when the engine is running obviously and the car is moving...
Down changing this arvo into 2nd I also noticed it was a little crunchy/grindy going into gear.

I find it odd that it just started happening after the car drove fine all the way to work in the morning.

The clutch was replaced about 4 weeks ago with a new heavy duty exedy plate and high clamp pressure plate if it makes and difference... The box was filled with Nulon smooth shift 75-90 oil and a tube of G70.

Any ideas would be much appreciated

Cheers
