The 1680-17 Center Support Bearing is a crucial component for the Mitsubishi Lancer, specifically designed to support the front center bearing on a three-piece driveshaft. This bearing features a 1.181″ inner diameter, which is critical for ensuring a snug fit on the driveshaft, preventing any unwanted play that could lead to vibration or misalignment. With a center-to-center mounting hole spacing of 7.750″, this bearing maintains the proper alignment of the driveshaft, which is essential for optimal performance and longevity.
Engineers selected this configuration to address the specific load cases encountered in the Lancer’s driveline. The rubber isolator within the bearing absorbs vibrations, which is vital for reducing noise and enhancing driving comfort. If the isolator becomes hardened or collapses, it can lead to increased vibration at highway speeds, bearing noise, and premature wear on surrounding components.
When installing the 1680-17, it’s important to avoid pre-loading the rubber isolator. Proper alignment of the mounting bracket before tightening is crucial to prevent altering the driveshaft’s operating angle. Regular inspection of the bearing for signs of rubber deterioration can help catch issues early, ensuring the driveline remains smooth and efficient.
