J.C. Whitney JK28370002 Front Wheel Hub Assembly with Bearing 5-Lug OEM Replacement

The J.C. Whitney JK28370002 is a direct-fit OEM replacement front wheel hub assembly designed for the Kia Optima (2016–2019) and Kia Sportage (2016–2019). This hub assembly integrates the wheel bearing and hub into a single, ready-to-install unit, simplifying the replacement process and restoring factory-level performance.

The wheel hub assembly serves as the critical interface between the vehicle's suspension, braking system, and the wheel itself — enabling smooth, low-friction wheel rotation while securely connecting the wheel and brake components to the vehicle. A worn or failed hub bearing can produce humming noises, vibration, and unsafe handling, making timely replacement essential.

Key Features:

• Direct OEM replacement design for precise fit and function
• Integrated wheel bearing pre-installed — no separate bearing press required
• 5-lug bolt pattern to match factory wheel specifications
• Fits both driver side (LH) and passenger side (RH) front positions
• 4-bolt square flange mounting configuration
• Cross-reference part number: 513374
• Engineered to meet or exceed original equipment specifications

This hub assembly is a one-piece, bolt-on replacement that eliminates the need to source a separate bearing, reducing installation complexity. It is engineered for durability and long service life, making it a reliable choice for restoring safe and quiet wheel operation to your Kia Optima or Sportage.
