Product Introduction

The 3463320416 Steering Knuckle is a critical steering and suspension component designed for Mercedes-Benz SK series and Beiben NG80 heavy-duty trucks.

Installed on the front axle, the steering knuckle forms the connection between the front axle beam, king pin assembly, wheel hub, brake components, and steering linkage. It enables the front wheels to pivot accurately during steering while supporting heavy vehicle loads.

The steering knuckle works together with:

• Front axle beam
• King pin repair kit
• Wheel hub assembly
• Wheel bearings
• Brake drum or brake disc assembly
• Tie rod end
• Drag link

During heavy-duty transportation, the steering knuckle is subjected to continuous steering forces, braking loads, road impacts, and vibration. Excessive wear or deformation can result in:

• Steering looseness
• Abnormal wheel alignment
• Uneven tire wear
• Front axle vibration
• Poor steering response
• Reduced driving safety

The 3463320416 steering knuckle is manufactured from high-strength forged alloy steel using precision CNC machining and heat treatment processes. The accurately machined king pin bore and bearing mounting surfaces ensure excellent assembly precision and long-term reliability.

Designed according to OEM specifications, this steering knuckle provides direct replacement compatibility for Mercedes-Benz SK and Beiben NG80 front axle systems. It is widely used for steering system repair, front axle overhaul, fleet maintenance, and commercial truck rebuilding projects.

Each steering knuckle undergoes strict quality inspections including material testing, dimensional verification, hardness testing, machining accuracy inspection, and installation fitment verification to ensure consistent OEM-quality performance.
