Replacement RT28080047 Front Right Steering Knuckle & Wheel Bearing Hub Assembly FWD 3.5L

The Replacement RT28080047 is a front right (passenger side) steering knuckle and wheel bearing hub assembly engineered as a direct OEM-quality replacement for front-wheel drive (FWD) applications with the 3.5L V6 engine. This loaded knuckle assembly includes the hub and bearing pre-installed, saving significant labor time compared to replacing individual components.

The steering knuckle is a critical front suspension component that houses the wheel hub and bearing, connects to the upper and lower control arms via ball joints, and links to the steering system through the tie rod end. A worn or damaged knuckle can cause symptoms such as hard braking, difficult wheel turning, uneven tire wear, vehicle pulling, and wheel vibration or wobble.

Key Features:

• Front right (passenger side) installation position
• FWD (front-wheel drive) application — 3.5L V6 engine
• Loaded assembly: steering knuckle, wheel hub, and bearing included
• Steel construction for strength and durability
• Direct bolt-on fitment — no modifications required
