3680-11 – Center Support Bearing – Gm Application – 1.181″ ID – 3.300″ Center Bearing To Base

The 3680-11 center support bearing is a critical component for maintaining the integrity of the driveshaft in GM vehicles, specifically the Acadia, Traverse, and Enclave. With a bearing inner diameter of 1.181 inches, this part ensures a snug fit, which is essential for optimal performance. The center-to-base height measures 3.300 inches, providing the necessary alignment to prevent driveline vibrations.

One of the standout features of the 3680-11 is its mounting hole spacing of 7.125 inches, which is crucial for proper installation. If the mounting geometry is off, it can lead to misalignment and increased wear on the driveshaft. This bearing’s design helps absorb vibrations, thanks to its rubber isolator, which can deteriorate over time. A collapsed or hardened isolator can lead to noticeable vibration at highway speeds, making it vital to monitor the condition of this component.

• Application: GM vehicles (Acadia, Traverse, Enclave)
• 1.181″ Bearing ID for precise fit
• 3.300″ Center Bearing To Base for proper alignment
• 7.125″ Center To Center Of Mount Holes for accurate installation
• Check for rubber isolator condition to prevent vibration issues

When installing the 3680-11, avoid pre-loading the rubber isolator and ensure the mounting bracket is aligned before tightening. This attention to detail will help maintain the driveshaft’s operating angle and extend the life of the component.
