Morphology

kingbolt = king + bolt (semi-transparent) = king + bolt

The components 'king' (chief) and 'bolt' (fastener) are clear, but the specialized mechanical meaning 'main pivotal bolt in a steering axle' is a technical extension not obvious to all learners.

Etymology

Kingbolt comes from the parts king ('chief', 'main') and bolt ('a strong metal pin'). So a kingbolt is the main bolt or pin that forms the pivot for the front axle and steering, which is why a broken one makes driving unsafe.
