What is a Steering Knuckle?

The steering knuckle is a critical front suspension component that houses the wheel hub and bearing, and serves as the pivot point for steering. It connects to the upper and lower control arms via ball joints and to the steering system via the tie rod end, allowing the wheel to turn, spin, and move through suspension travel.

Key Features:

• Direct OEM replacement — designed to match original equipment dimensions and mounting points
• Front right (passenger side) position
• Cast construction for durability and long service life
• Hub, axle, and ball joint not included — knuckle only
