9980-46 – Center Support Bearing – Subaru Application – 1.181″ ID – 750″ Center Bearing To Base

The 9980-46 center support bearing is engineered specifically for Subaru applications, providing crucial support for two-piece driveshafts. With a bearing inner diameter of 1.181 inches, this component ensures a snug fit that maintains alignment and reduces driveline whip. The center-to-base height of 0.750 inches is critical; it helps maintain the correct operating angle of the driveshaft, preventing unnecessary wear and vibration.

One of the standout features of the 9980-46 is its offset mounting brackets. One bracket is positioned evenly, while the opposite is offset by 0.75 inches. This design allows for precise alignment during installation, which is essential for optimal performance. The center-to-center distance of 6.625 inches between the mounting holes further supports proper alignment, ensuring that the driveshaft operates smoothly.

When installing the 9980-46, remember to avoid pre-loading the rubber isolator, as this can lead to premature failure. Proper alignment of the mounting brackets before tightening is also crucial. Symptoms of a failing center support bearing include driveline vibrations at highway speeds, bearing noise, and visible rubber deterioration. Regular inspection of this component can help prevent these issues.
