9980-20 – Center Support Bearing – Isuzu Application – 1.181″ ID – 3.125″ Center Bearing To Base

The 9980-20 center support bearing is essential for maintaining the integrity of the driveshaft in Isuzu vehicles, particularly in four-wheel-drive Trooper models from 1988 to 1991. This part plays a critical role in supporting a two-piece driveshaft at its midpoint, ensuring proper alignment and minimizing whip during operation. With a bearing inner diameter of 1.181 inches, this component is precisely engineered to fit snugly within the driveshaft assembly.

One of the key specifications of the 9980-20 is its center-to-base height of 3.125 inches. This dimension is crucial as it helps maintain the correct operating angle of the driveshaft, preventing unnecessary wear and tear on other driveline components. The center-to-center distance of 3.625 inches between the mounting holes allows for secure installation, while the M12-1.25 threaded holes ensure a robust connection.

• Application: Isuzu
• 1.181″ Bearing ID
• 3.125″ Center Bearing To Base
• 3.625″ Center To Center Of Mount Holes
• Installation Tip: Align the mounting bracket before tightening to avoid pre-loading the rubber isolator.

When the rubber isolator deteriorates or collapses, it can lead to driveline vibration, particularly noticeable at highway speeds. Therefore, regular inspection of the 9980-20 is recommended to ensure optimal performance. By addressing these factors, the 9980-20 center support bearing helps extend the service life of the driveline under load conditions, making it a vital component for Isuzu applications.
