It slides on a splined shaft, allowing the driveshaft length to change as the suspension moves while still transmitting torque reliably. You’d replace it if the splines are worn, the yoke is cracked, or the u‑joint bore is damaged, which can cause vibration or driveline noise. This forged steel yoke accepts a 1310 series u‑joint with 1.062‑inch bearing caps and includes a press‑on seal for protection.
