This front axle cross joint transmits torque from the steering gear to the wheel hubs, allowing the axle to articulate while maintaining drive. It sits at the center of the front axle assembly, connecting the two half-shafts through a universal joint. Wear in the cross joint produces play that causes steering wander and vibration under load. The manufacturer machines the cross to the same journal diameter and bearing cup depth as the original assembly, so the retaining clips seat fully and the needle bearings are not preloaded incorrectly. On installation, ensure the grease passages align with the lubrication points in the yoke.
