The white clip fixes the bearing to the arm, so when the clutch pedal is realsed (engine ideling or in gear) the bearing is pulled back and sway from the lever spring plate.

What had happened on this one was the clip either disintegrated, or as i suspect was never put it as there was no trace of it and the bellhousing is a sealed unit!. So the bearing was making contact with the spring plate under ideling and driving and bouncing around the shaft.

Its basically worn a groove into the spring forks on the clutch pressure plate. Will post a pic tommrow of the damage.

Why the hell landrover used this pathetic plastic clip anyway is beyone me tho.
