Well basically my gearbox is dead and partially because of the good old jolly powerflex dogbone mount I installed about a month or 2 ago due the fact the powerflex mount doesnt absorb much vibration from the gearbox my gearbox has managed to vibrate itself and crack the casing where the dogbone bolts to the gearbox resulting in a gearbox death!! Also if you do install an uprated mount on the dogbone check your gearbox oil level frequently incase of leeks.
