Overview of SKF Differential Pinion Bearing BR158

The SKF BR158 differential pinion bearing is engineered for reliable performance in Toyota Tundra driveline systems. Designed with precise dimensions, this bearing supports smooth differential operation and helps maintain drivetrain integrity.

• Inside diameter: 1.575 inches for accurate shaft fitment
• Width: 1.260 inches ensuring proper bearing thickness
• Outside diameter: 3.346 inches for secure housing placement
• Part number BR158 for exact replacement compatibility
• Compatible with Toyota Tundra differential assemblies

Technical Details and Specifications

The SKF BR158 differential pinion bearing features an inside diameter of 1.575 inches, which allows it to fit precisely on the pinion shaft of the Toyota Tundra. Its 1.260-inch width provides the necessary bearing surface to handle axial and radial loads within the differential. The outside diameter of 3.346 inches ensures a snug fit within the differential housing, minimizing play and wear. These dimensions are critical for maintaining proper gear alignment and smooth rotation under various driving conditions.

Compatible Vehicles and Applications

This differential pinion bearing is specifically designed for use in Toyota Tundra models. It is an essential component in the driveline and axles category, particularly for differential repair or rebuild projects. The SKF BR158 bearing is suitable for addressing issues related to differential noise, vibration, and premature wear caused by worn or damaged bearings.

• Eliminates differential whining or grinding noises
• Reduces vibration from worn pinion bearings
• Prevents excessive play in the differential pinion shaft
• Supports smooth gear engagement and power transfer
• Helps avoid differential overheating due to bearing failure

Installation Notes and Tips

When installing the SKF BR158 differential pinion bearing on a Toyota Tundra, ensure the bearing is properly seated within the differential housing to avoid misalignment. Use appropriate tools to press the bearing onto the pinion shaft without causing damage. Verify the bearing dimensions—inside diameter, width, and outside diameter—to confirm compatibility before installation. Proper lubrication and torque specifications should be followed according to Toyota service guidelines.
