Mopar Performance 68449604AA Differential Side Bearing Kit

The Mopar Performance 68449604AA is a genuine OEM differential side bearing kit designed to maintain optimal differential performance in Ram heavy-duty trucks. This precision-engineered bearing kit enables smooth differential operation by supporting continuous rolling motion while handling both axial and radial forces without generating excessive friction between components.

Key Features:

• Genuine Mopar OEM quality ensures factory-fit specifications and reliable performance
• Precision-engineered to support differential carrier operation and allow independent wheel rotation
• Handles both axial and radial loads while minimizing friction for extended service life
• Critical component for maintaining proper power distribution to drive wheels
• Backed by Mopar's factory warranty for peace of mind

Differential side bearings are essential components that support the differential carrier assembly within the axle housing. They allow the carrier to rotate smoothly while maintaining proper alignment and supporting the weight and forces generated during operation. When these bearings wear out, they can produce abnormal noises such as whining, humming, or grinding sounds, particularly during acceleration or deceleration. Replacing worn differential bearings promptly helps prevent further damage to the differential assembly and ensures continued safe vehicle operation.
