Description
AZ9981320136 differential assembly is the core power distribution spare part for Sinotruk Howo heavy truck drive axle. Installed inside the axle housing of the drive axle, it distributes the torque transmitted from the main reducer to the left and right driving wheels, allowing wheels to rotate at different speeds during turning, which reduces tire wear and guarantees stable cornering performance. The differential adopts high-strength alloy steel forging for internal gears, planetary gears, side gears and cross shaft. After professional heat treatment and precision machining, it can bear huge torque and impact load under heavy load, climbing and rough road conditions. Every differential assembly undergoes strict gear meshing inspection, backlash test and fatigue load test before delivery, to avoid gear pitting, broken teeth and abnormal noise. It is a key overhaul replacement part for vehicle axle maintenance. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
