New differential

So the front differential was never used since it was converted to 2WD mode. It came out in a single piece suitable for directly inserting in the rear. The mane spur gear was on the right. This got it driving in the right direction again, with no grinding.

The wheel base of the Ruckus is about 1/2 of the Lunchbox, so the Lunchbox wouldn't be a good replacement. The Ruckus is just narrow enough to fit on curbs in the city. The day job probably won't last another 400 miles, so the Lunchbox may still be a suitable replacement wherever the next day job is.

For better stability, a stiffer suspension would be the next idea. Metal gears would solve the differential issues. It's going to need new tires by 800 miles. Helas, the plastic wheel bearings are completely worn out. It can't steer with the current wheel bearings, so like any servicing of an old car, what started as a grinding sound turned into a stream of endless repairs.
