3680-30 – Center Support Bearing – Gm Application – 1.181″ ID – 1.500″ Center Bearing To Base

The 3680-30 center support bearing is a critical component for the 2004-2007 Cadillac CTS-V, designed to maintain alignment and reduce driveline vibration. With a bearing inner diameter of 1.181 inches and a center-to-base height of 1.500 inches, this part is engineered to handle the specific load conditions of GM applications. The center-to-center distance of 6.750 inches between the mounting holes ensures a secure fit, while the molded threaded nuts at each side mount bracket simplify installation and enhance reliability.

Using a center support bearing like the 3680-30 is essential for preventing driveline whip and maintaining the correct operating angle of the driveshaft. If you attempt to use a similar bearing without the exact specifications, you risk introducing vibration and noise, which can lead to premature failure of the driveline components. The rubber isolator in this bearing absorbs vibrations effectively, but if it becomes hardened or collapses, you will notice symptoms like increased vibration at highway speeds or bearing noise.

• Key Specs:
• 1.181″ Bearing ID
• 1.500″ Center Bearing To Base
• 6.750″ Center To Center Of Mount Holes
• Threaded nuts molded into housing for secure installation

When installing the 3680-30, ensure that you do not pre-load the rubber isolator. Align the mounting bracket before tightening to avoid misalignment and check the driveshaft runout to confirm proper installation. This attention to detail will help you achieve optimal performance and longevity from your driveline system.
