Drive Shaft seized on the final drive splines

[Grumpy Goat]

There I was sitting in the lounge at Brown's Motor Works having my 114K service. When the technician (AKA the BOY) ushered me to the
cone of silence, to inform me that I needed a new drive shaft not happy. All things considered no better get this news. Visually the drive shaft look fine
but the U-joints where very notchy.

Mark, that was good albeit expensive news. The driveshaft monitoring paid off and you were saved from a catastrophic failure while riding at speed. The costs there would surely have been higher.
