Dipping the ckutch removes the load from the drive train, so it's not necessarily the clutch, it could be something in the drive train from the clutch to the wheels.
If you are careful you can jack the van up and fit axle stands and get an asssistant to run the engine in gear and see if you can see/hear anything obvious from looking whilst it is turning all the drive train.
