Product Introduction 3001106N Steering Knuckle Side Pin is the pivotal rotating shaft fitted on HFC6700 commercial vehicle front axle knuckle. It acts as the rotation axis for steering knuckle, supporting weight load while allowing knuckle to swing freely for wheel direction adjustment. This aftermarket replacement pin resolves stiff steering, excessive wheel clearance and abnormal knocking noise caused by pin surface abrasion, thread wear and metal corrosion of original pins, maintaining steering flexibility and reducing uneven tire wear for regional cargo delivery vehicles.
Product Advantages High-grade alloy steel with thermal treatment delivers outstanding load-bearing capacity and wear resistance. Precision ground outer surface ensures smooth rotational movement with matching bushing. Anti-rust surface treatment slows corrosion from muddy and wet road environment. Each pin undergoes dimensional inspection before shipment, stable structural support and simplifies front axle steering maintenance work.

FAQ
Q1: What maintenance should I do to extend king pin service life?
A1: Regularly inject chassis grease to expel water and dirt inside the pin and bushing assembly.
Q2: What risk exists if king pin clearance becomes too large?
A2: Loose gap creates steering wander and will trigger irregular tire abrasion on front wheels.
Q3: Can bent side pin continue to be reused?
A3: Never reuse bent pins, deformation changes force distribution and may cause steering safety risks.
