Wheels are not organs. For the rest of your list, the relation between the two terms is very unclear.
It depends on native idioms. So, Slavic languages have an idiom "to devoir by eyes". it is the same as to eat a food. A mouth does relocation of food from one place (a plate) to another (a stomach). Eyes do relocation of an image from one place (around a looker) to another (into a brain, into a virtual space). Also, eyes are the organ of mental locomotion, because they relocate you from the place where you are really "lon" to another place, where an object of your interest is. A dream (an imagination) is an organ of locomotion to the future or to the past.
"kon -- lipu" (air -- a leaf of a plant). An atmosphere has own hands and legs. Basically, it is a stream of wind ("linja kon"="luka kon", "noka kon"). One air stream is one a hand or a leg. A tornado swirl is obviously a leg of the Big Air Daemon, which makes as huge locomotion of cars as a football player does. Another couples do own types of locomotions. It is simple, who has a pregnant imagination.
... like Zeus with Palada.
A leg is an appendage (limb), not an organ
1) any organ has own function "f(x)=y".
2) A leg has own function -- locomotion
3) The leg is the organ.

a->b, c->b, a=c
just following janpona on that; wheels aren't limbs either or any other part of a living creature, so not apt to be 'noka'.
1) wheels are organ of locomotion.
2) limbs are organ of locomotion.
3) "noka" is organ of locomotion.
4) wheel are limbs are "noka"
