Description
When diagnosing driveline issues in Subaru vehicles, the 9980-51 center support bearing is often a key component to consider. This bearing supports a two-piece driveshaft at its midpoint, maintaining alignment and reducing whip. If you experience vibration at highway speeds or hear bearing noise, the 9980-51 is likely the culprit. Its specifications include a 1.181″ ID and a center-to-base height of 0.750″, which are critical for maintaining the correct operating angle of the driveshaft.
One of the common failure symptoms is rubber deterioration in the isolator, which can lead to increased vibration. If the rubber is hardened or collapsed, you’ll notice driveline vibrations that can be traced back to this bearing. The 9980-51 also features a center-to-center distance of 6.750″ between the mounting holes, which is essential for proper installation. Note that this bearing mounts at an offset, with one bracket positioned below 0.75 inches while the opposite side mounts evenly. This offset must be accounted for during installation to avoid pre-loading the rubber isolator.
