SA54-25-300 Center Support Bearing Ford Ranger / Courier 4X4 Bearing ID: 35mm

When installing the SA54-25-300 Center Support Bearing, it’s crucial to ensure proper alignment to maintain driveline integrity. This bearing supports a two-piece driveshaft at its midpoint, which helps reduce whip and maintain alignment. The critical dimensions of this component include a 1.378″ bearing ID, a center-to-base height of 2.565″, and a center-to-center mounting hole spacing of 6.875″. These specifications are essential for ensuring that the driveshaft operates smoothly without introducing unwanted vibrations.

Before installation, check the condition of the rubber isolator. A hardened or collapsed isolator can lead to increased driveline vibration, which is often noticeable at highway speeds. Common failure symptoms include bearing noise and visible rubber deterioration. To avoid pre-loading the rubber during installation, align the mounting bracket carefully before tightening the fasteners. This step is critical to prevent altering the driveshaft’s operating angle.

• Check the rubber isolator for wear or damage.
• Align the mounting bracket before tightening to prevent pre-load.
• Verify the center-to-base height of 2.565″ for correct fitment.
• Ensure the center-to-center hole spacing measures 6.875″ for proper installation.
• Monitor for vibrations post-installation to confirm successful alignment.

Using the SA54-25-300 Center Support Bearing will ensure your Mazda or Ford driveshaft remains stable and aligned, contributing to a smoother ride.
