Product Description
Product Introduction
Structure: A complete assembly including a robust cast iron differential case, precision-machined bevel gear set (side gears and pinion gears), cross shaft, and mounting hardware (bolts, flanges). The case features integrated oil passages for lubrication and cooling, while the gears are precision-cut for optimal meshing.Performance: Efficiently transmits torque to the drive wheels while allowing them to rotate at different speeds during cornering, ensuring stable and predictable handling. The precision-machined gears minimize friction and noise, while the heavy-duty construction withstands the high torque loads of heavy-duty operation.Design: Directly interchangeable with original equipment, engineered to fit perfectly with the drive axle housing and drive shafts, maintaining precise gear alignment and reducing wear.
Core Function
Torque Distribution: Transmits torque from the drive shaft to the drive wheels, allowing them to rotate at different speeds during cornering.
Load Bearing: Withstands the high torque loads generated during heavy-duty operation, ensuring reliable performance under extreme conditions.
Lubrication & Cooling: Integrated oil passages ensure proper lubrication of the gear set, reducing friction and extending service life.
OE Replacement: Directly interchangeable with the original differential assembly, preserving the drive axle’s performance and safety.
Precision-Engineered Sinotruk Differential for Maximum Drivetrain Performance
When your fleet depends on uninterrupted hauling across demanding routes, a failing differential is not an option. The Mettlead WG9231320071 Sinotruk differential assembly delivers OEM-grade fitment and durability at a competitive price point — backed by strict quality control from our China-based manufacturing facility.

Features & Benefits
Complete Differential Assembly — Zero Guesswork
This is a drop-in replacement unit. No sourcing individual components. The WG9231320071 ships as a fully assembled differential including case, gear set, cross shaft, and all mounting hardware.
Precision-Machined Bevel Gear Set
Side gears and pinion gears are CNC-cut to tight tolerances, ensuring optimal meshing, reduced noise, and extended service life under heavy loads. Proper gear contact patterns mean less heat generation and fewer premature failures.
Robust Cast Iron Differential Case
The housing is cast from high-strength iron with integrated oil passages engineered for consistent lubrication flow and thermal management. This keeps operating temperatures stable even during sustained high-torque operation.
Direct OEM Cross-Reference
Part number WG9231320071 is a direct replacement for Sinotruk HOWO series trucks. Bolt pattern, spline count, and gear ratios match factory specifications — no modifications required.
Strict Quality Control
Every unit undergoes dimensional inspection, gear runout testing, and surface hardness verification before shipment. Mettlead maintains batch traceability so you can order with confidence at scale.
