Replacement RT28080014 Front Left Steering Knuckle Assembly AWD

The Replacement RT28080014 is a front driver side (left) steering knuckle designed as a direct-fit OEM replacement for All Wheel Drive applications. This steering knuckle — also referred to as a steering spindle — 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.

Key Features:

• Direct OEM replacement — engineered to match original equipment specifications for a proper fit and function
• Driver side (left) front positioning — correct for AWD drivetrains
• Restores suspension integrity — addresses symptoms such as uneven tire wear, clunking over bumps, or excessive wheel play
• Compatible with All Wheel Drive (AWD) configurations — not for use on front-wheel drive variants
