The 1680-20 Center Support Bearing is a crucial component for maintaining the integrity of a two-piece driveshaft, particularly in Mitsubishi and Dodge applications. With a bearing ID of 1.181 inches, this part ensures a snug fit that helps to stabilize the driveshaft at its midpoint. This stability is essential for reducing whip and maintaining proper alignment, which directly impacts the driveline’s performance.
One of the standout features of the 1680-20 is its center-to-center mounting hole spacing of 6.375 inches. This dimension is critical because it dictates how the bearing interacts with the surrounding components. If this measurement is off, it can lead to incorrect driveshaft angles, resulting in excessive vibration and potential failure. The rubber isolator in this bearing plays a vital role in absorbing vibrations; if it becomes hardened or collapses, you may experience noticeable driveline vibrations, especially at highway speeds.
When installing the 1680-20, it’s essential to avoid pre-loading the rubber isolator. Proper alignment of the mounting bracket before tightening is crucial to ensure optimal performance. Additionally, always check the driveshaft runout to prevent future issues.
