The 1380-20 Center Support Bearing is engineered specifically for TOYOTA applications, particularly the Pickup 4X4 models from 1979 to 1988. With a Bearing ID of 1.181 inches, this component plays a crucial role in maintaining the alignment of a two-piece driveshaft. The 3.750-inch center bearing to base measurement is critical; it ensures that the driveshaft operates at the correct angle, preventing unnecessary wear and tear on the driveline.
One of the key features of the 1380-20 is its 9.375-inch center-to-center distance between the mounting holes. This dimension is essential for proper installation, as it allows for accurate alignment of the driveshaft, reducing the risk of vibration and potential failure. When the rubber isolator within the bearing is functioning correctly, it absorbs vibrations effectively, enhancing the overall performance of your TOYOTA’s drivetrain.
Failure to replace a worn or collapsed center support bearing can lead to noticeable symptoms, such as vibrations at highway speeds or bearing noise. To ensure a successful installation, follow these guidelines:
- Do not pre-load the rubber during installation.
- Align the mounting bracket before tightening.
- Check driveshaft runout after installation.
In summary, the 1380-20 Center Support Bearing is a vital component for maintaining the driveline integrity of your TOYOTA Pickup 4X4 (79-88). Its precise dimensions and robust design ensure reliable performance and longevity.
