9980-42 – Center Support Bearing – Subaru Application – 1.181″ ID – 1.500″ Center Bearing To Base

The 9980-42 center support bearing is specifically engineered for Subaru vehicles, providing essential support for two-piece driveshafts. With a bearing inner diameter of 1.181 inches, this component is designed to maintain alignment and reduce driveline whip, crucial for smooth operation at highway speeds.

One of the standout features of the 9980-42 is its unique offset mounting configuration. The center-to-base height measures 1.500 inches, while the center-to-center distance between the mounting holes is 6.750 inches. This means that one bracket sits below 1.50 inches while the opposite side mounts at 0.75 inches. This offset is critical; using a bearing with incorrect dimensions can lead to misalignment and increased vibration, which can cause premature failure of the driveline components.

When installing the 9980-42, it’s important to avoid pre-loading the rubber isolator during installation. Proper alignment of the mounting bracket before tightening is essential to prevent driveline vibration. Symptoms of a failing center support bearing include noticeable vibration at highway speeds, bearing noise, and rubber deterioration. Regular checks can help catch these issues early.
