It holds the rear driveshaft via a U‑joint and strap, transmitting engine torque to the axle. You typically replace this yoke when the internal splines are worn or stripped, the yoke ears are cracked or out‑of‑round, or during a U‑joint overhaul when the old yoke shows corrosion or fretting. Designed for heavy‑duty SPL170 series drivelines, it includes the strap kit and slinger for a complete installation.
