Morphology
The phrase combines 'dead' (not functioning) with 'axle' (rod wheels rotate around), so its meaning—an axle that does not transmit driving power—is directly inferable from the constituents. Although domain-specific, the adjectival use of 'dead' to indicate lack of function is common in English and cross-linguistically, so a B1 learner who knows both words would likely understand it.
Etymology
Dead axle comes from a simple image: the axle is dead because the axle does not give power and just supports the wheel. So dead axle means an axle that holds or supports a wheel but is 'not powered'.
