9980-26 Center Support Bearing Colorado, Canyon, Isuzu I-280, I-290, I-370, M12-1.75 threaded 89040334, HB1595-10, 9980-26

The 9980-26 center support bearing plays a crucial role in maintaining the alignment and stability of a two-piece driveshaft, particularly in light-duty applications like the Chevrolet Colorado and GMC Canyon, as well as Isuzu I-280, I-290, and I-370 models. With a bearing inner diameter of 1.181 inches, this component ensures a precise fit that directly affects the driveline’s performance.

One of the key specifications of the 9980-26 is its center-to-base height of 4.000 inches. This dimension is critical because it helps maintain the correct operating angle of the driveshaft, preventing unnecessary wear and tear on the U-joints and other driveline components. Additionally, the center-to-center distance of 3.625 inches between the mounting holes allows for proper alignment during installation, which is essential for reducing vibration and enhancing overall driveline stability.

• Ensure proper alignment of the mounting bracket before tightening.
• Do not pre-load the rubber isolator during installation to avoid premature failure.
• Check the driveshaft runout after installation to confirm proper function.

Symptoms of a failing center support bearing may include vibrations at highway speeds, bearing noise, and visible rubber deterioration. Regular inspection and timely replacement of the 9980-26 can prevent these issues, ensuring a smoother ride and extending the lifespan of your driveline components.
