Differential Side Bearing Kit - Mopar (68340251AA)

The Differential Side Bearing Kit - Mopar (68340251AA) is a genuine OEM drivetrain service component engineered to support and stabilize the differential carrier assembly within the axle housing. Manufactured to Mopar’s exact factory specifications, this differential side bearing kit ensures proper bearing preload, smooth differential operation, and dependable drivetrain performance under demanding driving conditions.

Constructed from high-strength automotive-grade bearing steel and precision-machined components designed for heavy-load drivetrain applications, this differential side bearing kit is built to withstand continuous rotational stress, friction, heat, and gear loading. Its durable construction helps resist premature wear, surface fatigue, corrosion, and bearing failure for long-lasting operational reliability and drivetrain durability.

Functionally, the differential side bearings help support the differential carrier while maintaining proper ring and pinion gear alignment inside the axle assembly. Correct bearing operation is essential for minimizing drivetrain friction, reducing vibration, and maintaining smooth power transfer to the wheels. Worn or damaged side bearings may contribute to gear noise, excessive backlash, vibration, uneven gear wear, or reduced differential performance.

As a genuine Mopar OEM component kit, this differential side bearing kit is manufactured to precise factory load tolerances, bearing dimensions, preload specifications, and fitment requirements to ensure direct compatibility with the original differential assembly. This guarantees accurate installation, dependable gear support, and factory-level drivetrain performance compared to aftermarket alternatives.

Installation is recommended during differential rebuilds, axle service procedures, gear replacement projects, or when diagnosing bearing noise and excessive drivetrain wear. Proper installation helps maintain correct gear alignment, smooth differential rotation, and reliable axle operation.
