Product Introduction

The 3353320101 Steering Knuckle is a critical steering and suspension component designed for Mercedes-Benz SK, MK, NG series, and Beiben NG80 heavy-duty trucks.

Mounted 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 allows the front wheels to pivot accurately while supporting the weight of the vehicle and maintaining proper steering geometry.

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 constantly subjected to steering loads, braking forces, road shocks, and vibration. Excessive wear, cracks, or deformation can lead to:

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

The 3353320101 steering knuckle is manufactured from high-strength forged alloy steel using precision CNC machining and heat treatment. The accurately machined king pin bore, bearing seats, and mounting surfaces ensure excellent assembly precision, smooth steering operation, and extended service life.

Designed according to OEM specifications, this steering knuckle provides direct replacement compatibility for Mercedes-Benz SK, MK, NG, 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 analysis, hardness testing, dimensional verification, machining accuracy inspection, and installation fitment testing to ensure OEM-level reliability and durability.
