It supports the middle of a two‑piece driveshaft, using a rubber cushion inside a steel canister to isolate engine and road vibration. When the rubber deteriorates or the bearing fails, you’ll often hear squeaking or feel excessive driveline vibration, signaling it’s time to replace it. The assembly includes the bearing, rubber mount, dust boot, and mounting bracket for a bolt‑in repair on 1350‑series driveshafts.
