3580-45 – 45 – Center Support Bearing – Lincoln Navigator Application – 1.574″ ID

The 3580-45 Center Support Bearing is engineered specifically for the Lincoln Navigator, providing essential support for a two-piece driveshaft. With a bearing ID of 1.574 inches, this component ensures proper alignment and minimizes driveline whip, which is crucial for maintaining smooth operation. The 2.125-inch center-to-base height is critical; it prevents changes in the driveshaft’s operating angle during installation, which can lead to vibrations and premature wear.

Another key measurement is the 6.181-inch center-to-center spacing of the mounting holes. This dimension is vital for ensuring that the bearing aligns correctly with the driveshaft and the vehicle’s chassis. If the mounting holes are misaligned, it can result in excessive vibration and noise, indicating potential failure.

When installing the 3580-45, remember to avoid pre-loading the rubber isolator. Proper alignment of the mounting bracket before tightening is essential to prevent driveline issues. Additionally, check for any runout in the driveshaft to ensure optimal performance.
