Correct!
Pulling into Supermarket car park. Sudden loss of drive. No horrid sounds, just no drive.
My first thought was it was the gearbox, not this time, but that will happen some time, it's an LT77 after all.
Sticking the diff lock on restored drive, so I limped it home to investigate. With diff lock disengaged, and gear selected, the front prop shaft turned.
Hm. Diff? Half shaft?
I needed to do the front pads and a damper turret anyway, so I decided to strip down and take a look. I got lucky, it wsa just the CV joint. Phew! It's quite novel having something go wrong and it not needing megabucks spent on it.
