Front Axle Knuckle 8972615491 8-97261549-1 for ISUZU 700P NPR 4HK1
Product Overview
The Front Axle Knuckle (Steering Knuckle) with OEM numbers 8972615491 / 8-97261549-1 is a verified direct-fit replacement for ISUZU 700P / NPR series medium/heavy-duty trucks equipped with the 4HK1 5.2L diesel engine. This critical structural component connects the front suspension and steering systems, supporting vehicle weight and enabling wheel steering.
How It Works
Mounted at both ends of the front axle via king pins, the steering knuckle connects to the steering tie rod at the upper portion and mounts the front wheel hub through wheel bearings at the lower portion. When steering force is applied, the knuckle rotates around the king pin to turn wheels while bearing vertical, braking, and cornering loads.
