So far the thread has been mercifully free of major works. You may recall if you followed the saga at the time, that Simon (Mandrake) did a replacement of the transfer gear/reduction gear on his Leaf with a unit sourced from a breakers, in what I would describe as major work, and a bit of pioneering. Henceforth I will describe this as "the Gearbox" but its not a proper gearbox more a direct transfer of drive from the motor to the roadwheels thus, simple as ABC
The "box" with its clothes off
Anyone who has ever removed a gearbox from any car whether to "do the Clutch" or for more serious gearbox work will have gone through similar steps to remove the box. With the job being pioneering a bit of energy was expended working out whether the gearbox on the Leaf could be removed without dismantling the "stack" of components ie the charger and the inverter and all the high voltage stuff. Turns out it could be removed with the removal of a few mounting bolts then removed from the side, like any other "box" on a FWD car..

The problem was solved, but the original cause never revealed. I suspect that it was nothing to do with the gears /bearings themselves very little to go wrong there, but the pawl on the parking brake which drops down and engages with a castellated ring on the primary drive coming from the motor which you will see on the "teardown" video. Saying that the replacement "box with all the gubbins" from the breaker was probably still less than the price of the pawl or ring/parking brake from Nissan, even if it was available.
Simon's Saga starts pretty much here, with his videos of "the noise" if you want to follow it through
