The 81394106037 Center Support Bearing is crucial for maintaining the alignment of a two-piece driveshaft in multiple semi trucks. With a bearing ID of 2.362″ and a center-to-base height of 3.750″, this component plays a vital role in reducing driveline vibration and preventing whip. Before installation, ensure that you check the center-to-center distance of the mounting holes, which measures 8.625″. This dimension is essential to avoid altering the driveshaft’s operating angle.

When you’re ready to install, remember not to pre-load the rubber isolator. Align the mounting bracket carefully before tightening to ensure optimal performance. A common mistake is failing to check the condition of the rubber isolator; any signs of deterioration can lead to increased vibration and noise while driving. If you notice these symptoms, it may be time to replace the bearing.

• Verify the bearing ID of 2.362″ before installation.
• Ensure the center-to-base height is 3.750″ to maintain proper alignment.
• Check the center-to-center distance of mounting holes at 8.625″.
• Inspect the rubber isolator for any signs of wear or collapse.
• Do not pre-load the rubber during installation.

With the right attention to detail, the 81394106037 Center Support Bearing will deliver reliable performance in your semi truck application.
