Description
When you’re ready to install the 9980-50 center support bearing, it’s crucial to understand its specifications and how they affect your Subaru’s driveline. This bearing has a 1.181″ ID and a center-to-base height of 1.750″, which are critical for maintaining proper alignment and reducing vibration. The center-to-center distance between the mounting holes is 6.750″, so make sure to measure accurately before installation.
One common mistake during installation is pre-loading the rubber isolator. This can lead to premature failure and increased vibration. Instead, align the mounting bracket properly before tightening any fasteners. Remember, the offset mounting configuration means one bracket sits below 1.75″ while the opposite side mounts at 0.75″. This is essential for correct alignment and function.
- Check that the bearing ID is 1.181″ for compatibility.
- Ensure the center-to-base height is set to 1.750″ to avoid changing the driveshaft operating angle.
- Verify the center-to-center distance of 6.750″ between mounting holes.
- Do not pre-load the rubber isolator during installation.
- Align the mounting bracket before tightening to prevent driveline vibration.
Failure symptoms such as vibration at highway speeds or bearing noise can indicate issues with the center support bearing. Regular checks of the rubber isolator for deterioration can help maintain optimal performance. The 9980-50 is designed for service life under load conditions, making it a reliable choice for your Subaru.
