Driveline Yoke
Mack

The driveline yoke is a critical link in the vehicle’s universal joint system, connecting the driveshaft to the adjoining componentry with precise alignment and robust strength. Forged or machined from high-grade steel, this yoke features clean machining surfaces and tight tolerances to ensure smooth articulation under dynamic loads and varying temperatures. Its design supports consistent joint angle changes, reduces vibration transmission, and helps maintain proper splined engagement and bolt alignment throughout service life. For technicians, selecting the correct yoke involves matching the U-joint size, spline count, and overall length to the transmission or axle assembly. Proper installation includes checking runout, securing fasteners to the recommended torque, and confirming that seals or slip yokes are compatible with existing driveline components. This part is integral to reliable acceleration, braking stability, and fatigue resistance in Mack trucks operating under demanding conditions.
