This axle cross transmits torque through a universal joint at the intersection of two rotating shafts. It sits in the driveline between the gearbox output and the implement input, accommodating angular misalignment as the machine articulates or the attachment moves. Wear on the cross pins or needle bearings produces driveline vibration and a clicking sound during rotation. As an original component, the cross is machined to match the yoke bore diameter and pin length of the assembly it replaces, so no shimming or bushing adapters are required. On installation, pack the needle bearings with the specified grease and torque the retaining clips or circlips to the service manual value.
