OEM Left Steering Knuckle Arm 3003401LD291 for JAC N56 Kompas-5 Light Truck — Direct Fit Steering System Component, 3-Month Warranty
Function :
The Steering Knuckle Arm with OEM number 3003401LD291 is a direct-fit replacement left-side steering arm for JAC N56 (and Kompas-5) light trucks. This component connects the steering linkage to the steering knuckle, transmitting steering input to the front wheel for directional control.
Working Principle: The steering knuckle arm (also called a steering arm or spindle arm) is bolted to the steering knuckle. It provides the attachment point for the tie rod end. When the steering wheel is turned, the tie rod pushes or pulls the arm, pivoting the knuckle and wheel around the kingpin or ball joint axis. A worn or bent arm causes steering play, imprecise tracking, and abnormal tire wear.

Install new steering arm. Torque mounting fasteners per OEM specification (⚠️ torque spec pending — verify against JAC manual).
-
Reconnect tie rod end. Torque nut to specification and install new cotter pin if applicable.
-
Perform professional four-wheel alignment.
-
Road test to verify steering response and absence of noise.
Maintenance Schedule: Inspect steering linkage at every oil change or every 20,000 km. Check for looseness, bends, or cracks. Replace immediately if any damage or excessive play is found. After any front-end impact, re-inspect the steering arm.
