Morphology

live + axle

The meaning 'an axle that transmits driving power' follows directly from combining 'live' (active, in operation/powered) with 'axle' (the rod wheels rotate around). Although automotive jargon, the compositional relation is straightforward—'live' marks the axle as powered rather than passive—so a B1 learner who knows the constituents can infer the MWE meaning.

Etymology

Live axle comes from the simple picture of the bar between the wheels—the axle—being 'alive' because the live part turns and carries engine power to the wheels. So, 'live' means it is powered (not a 'dead' axle that only holds weight), and the phrase refers to an axle that sends driving power to the wheels.
