1280-40 – Center Support Bearing – Nissan – Bearing ID 1.181 – Center bearing to base 2.500

When you’re working on a Nissan, the 1280-40 Center Support Bearing is a critical component to ensure proper alignment and vibration isolation. This bearing has a 1.181″ ID and a center bearing to base measurement of 2.500″, making it essential for maintaining the integrity of your two-piece driveshaft. With a center-to-center distance of mount holes at 6.000″, this bearing fits perfectly in various Nissan models, including the Infiniti and Frontier 4X4 from 1998 to 2003, as well as the Hardbody 4X4 (1986-1997), Pathfinder 4X4 (1987-2003), Xterra 4X4 (2000-2003), and QX4 4X4 (2000-2003).

Before installation, check the rubber isolator for signs of deterioration. A hardened or collapsed isolator can lead to unwanted driveline vibrations, especially at highway speeds. It’s crucial to avoid pre-loading the rubber during installation; instead, align the mounting bracket before tightening the fasteners. This will help maintain the correct center-to-base dimension and prevent any changes to the driveshaft operating angle.

• Verify the 1.181″ bearing ID for compatibility.
• Ensure the center bearing to base height is 2.500″.
• Check the center-to-center distance of mount holes at 6.000″.
• Inspect the rubber isolator for wear before installation.
• Align the mounting bracket properly to avoid pre-loading.

By following these steps, you can ensure that the 1280-40 Center Support Bearing will perform optimally, reducing vibration and enhancing the overall driveline performance of your Nissan.
