Since Saturday afternoon, a vibration has started to occur through the accelerator pedal. No noise is coming from the gearbox, diff etc and can only be felt througth the accelerator pedal.

Accelerating slowly results in no vibration, however when the accelerator is pushed further down, vibrations can be felt through the pedal almost as if something is loose and moving backwards/forwards.

I had an organic clutch fitted in November last year and have since driven just under 10k coming upto 79k on the pedometer. The clutch has not been abused by launches etc. There is no leaks noticable either.

I have been advised it could be flywheel or clutch but just wandered if any1 had this issue before it goes in for diagnosis and repair

 

forgot to mention that the clutch doesnt slip, no crunching from gearbox, and it doesnt step out of gear

 

slight update. I have noticed a slight gear box leak coming from the drivers driveshaft at the C joint as it comes out of the box. I have a new seal from Rowleys Performance so hopefully this will sort it..any ideas as to what it could be...

slight wear on the splines on the shaft?
Bearings gone?
Cluth/Flywheel?
