Hi Dawie,

The axle is attached to the chassis using a "pillar" bearing. This
type of pillar bearing houses balls and rollers in the middle of it.
This pillar bearing can be bolted to the chassis.
To preventing welding the axle to the bearing (which would melt the
seals, and may damage the bearing) there is what is called a
"grubscrew". All this basically is, is a bolt that you tighten and it
tightens onto the rear axle, preventing the axle from spinning inside
the bearing.
If you got a look at a few different types of bearings you would see exactly.

A differential can be added to the kart. Small ones exist on Tractor
(ride-on) lawnmowers and should be ok for a kart.
Best of Luck
