The steering knuckle (also called spindle carrier) is a critical suspension and steering component that connects the wheel hub to the control arms, tie rods, and brake assembly. It serves as the pivot point for wheel movement, enabling steering and supporting vehicle weight.
Wheel Hub Mount: Holds the wheel bearings and supports the wheel/tire assembly.
Steering & Suspension Linkage: Connects to tie rods (for steering) and control arms (for suspension travel).
Brake Attachment: Provides mounting points for brake calipers or drums.
Durable Construction: Typically made from forged steel or aluminum for strength and heat resistance.
Steering misalignment or pulling
Uneven tire wear
Grinding noises from wheel bearings
Excessive play in steering
Inspect for cracks, bearing wear, or corrosion during brake/suspension service.
Failure often requires replacement (not repairable).
Proper installation ensures safe handling, braking, and tire performance.
A damaged steering knuckle compromises steering control, braking, and wheel stability, making it essential for vehicle safety.
