J.C. Whitney JA28380006 Rear Wheel Hub Assembly OEM Replacement 4-Lug

The J.C. Whitney JA28380006 is an OEM-replacement rear wheel hub assembly engineered as a direct-fit solution. Designed for equal application on both the driver and passenger sides (RH=LH), this 4-lug hub assembly restores proper wheel mounting, bearing function, and ABS sensor integration to factory specifications.

A wheel hub assembly serves as the critical interface between the vehicle's suspension knuckle and the wheel/tire, housing the wheel bearing and providing the mounting flange for the wheel. Replacement is typically required when the integrated wheel bearing has failed — often indicated by grinding, rumbling, or whining noises while driving — or when an ABS or traction control warning light is triggered by a faulty wheel speed sensor ring.

Key Features:

• OEM Replacement: Designed to match original equipment specifications for proper fit and function
• Symmetrical Design: Single part fits both driver (LH) and passenger (RH) rear positions
• 4-Lug Configuration: Matches the factory lug pattern for correct wheel mounting
• Integrated Hub and Bearing: Complete assembly simplifies the replacement process
• Pre-Greased Bearing: Ready for installation right out of the box

This hub assembly is manufactured to restore factory ride quality and braking performance. Note that related hardware such as axle bolts and mounting bolts are typically single-use components and should be replaced during installation.
