| High Light | High-strength cast steel Front Axle Knuckle ，Precision-machined Steering Knuckle ，210×250×260mm LH Knuckle | ||
The Front Axle Knuckle (Left-Hand / LH) with OEM numbers 8972615500 / 8-97261550-0 (Factory No. 8-97261550-GC) is a verified direct-fit replacement for ISUZU NPR / 700P series medium/heavy-duty trucks equipped with 4HK1 5.2L or 4HF1 diesel engines. This knuckle is mounted on the front axle king pin and is a critical structural component connecting the front suspension system and steering system, responsible for supporting the vehicle's front weight and enabling wheel steering.
The steering knuckle is mounted at both ends of the front axle via king pins. The upper portion connects to the steering tie rod, while the lower portion mounts the front wheel hub through wheel bearings. When the driver turns the steering wheel, the steering gear transmits force through the tie rod to the knuckle, which rotates around the king pin, turning the wheels. The knuckle simultaneously bears vertical loads from the front of the vehicle, longitudinal loads during braking, and lateral loads during cornering — making it one of the most complex and highly stressed components in the front axle.
Replace immediately if any of these symptoms occur:
