The trunnion is a pivoting pin assembly located at the top of the swivel hub on the Defender's front axle, forming part of the steering and suspension linkage. It allows the swivel housing to articulate while maintaining correct geometry under load. Wear or failure of the trunnion results in excessive play in the steering, uneven tyre wear, and potential loss of steering precision - symptoms often mistaken for worn ball joints or track rod ends.
