ACDelco Steering Knuckle Assembly

The ACDelco Steering Knuckle Assembly is a replacement steering knuckle (also called a spindle or wheel knuckle) that connects the suspension, steering and brake components at each wheel. The knuckle holds the wheel hub and bearing. It also lets the wheel pivot for steering while carrying vertical and lateral loads from the road.

Key Features:

• Replacement design that restores the steering and suspension geometry the vehicle was built with
• Provides mounting points for the control arms, tie rod end, brake caliper and wheel hub assembly
• Built for strength and durability under steering, braking and cornering loads
• Backed by ACDelco, the GM-affiliated parts brand known for OEM-quality replacement components
• Helps resolve problems caused by a bent, cracked or worn knuckle, such as uneven tire wear, steering wander, vibration or clunking noises

Replacing a damaged steering knuckle helps keep handling and tire wear on track and supports safe, predictable steering. A professional wheel alignment is recommended after installation. Select the correct part number for your application from the available options on this page.
