A front steering knuckle (front spindle) is a suspension and steering component designed to hold the wheel hub, brake caliper, strut, and ball joints. It allows the wheel to pivot while maintaining proper suspension geometry and stability.

The steering knuckle connects the wheel assembly with control arms and steering links. Its condition directly affects vehicle handling, tire wear, and safety.

A damaged knuckle may show deformation, cracks, worn hub seats, damaged caliper mounts, or impact marks after an accident. This can lead to play in the suspension, incorrect wheel alignment, vibration, and reduced driving stability.
