The AZ7117451220/21 is a premium rear hub assembly designed specifically for the rear axle of SINOTRUK Howo T5G trucks, as well as other heavy‑duty chassis that share this wheel‑end configuration. This rear hub is a critical component of the vehicle’s driveline and braking system, supporting the weight of the vehicle, housing the wheel bearings, and providing the mounting surface for the brake drum and wheel.
The AZ7117451220/21 rear hub assembly is manufactured from high‑strength cast steel, selected for its excellent structural properties, fatigue resistance, and load‑bearing capacity. The casting is heat‑treated to relieve internal stresses and then precision‑machined on all critical surfaces, including the bearing bores, wheel stud holes, and brake drum mounting flange. This ensures a perfect fit and reliable performance over the life of the component.
This rear hub assembly is engineered to withstand the extreme loads, vibrations, and impacts typical of heavy‑duty truck operation. Its robust construction and precise machining contribute to reduced bearing wear, improved braking performance, and extended wheel‑end service intervals. Replacing a worn or damaged hub with the AZ7117451220/21 restores proper wheel alignment and ensures safe, reliable vehicle operation.
Common signs that the rear hub assembly needs replacement include excessive wheel play, unusual noise from the wheel end, uneven tire wear, and visible cracks or damage to the hub casting. Replacing the hub with the AZ7117451220/21 addresses these issues, restoring the vehicle’s wheel‑end integrity and ensuring continued safe operation. This OEM‑spec hub is the ideal choice for axle overhauls and preventive maintenance.
Whether you are performing a complete axle rebuild or addressing a specific wheel‑end concern, the AZ7117451220/21 Rear Hub Assembly T5G delivers the quality, strength, and durability that SINOTRUK Howo professionals expect.
The AZ7117451220/21 rear hub assembly is specifically designed for SINOTRUK Howo T5G trucks equipped with the standard rear axle configuration, as well as other heavy‑duty chassis that utilize this wheel‑end design. It is a direct OE replacement, ensuring a perfect fit with the existing axle housing, brake drum, and wheel stud pattern without the need for modification or fabrication.
This rear hub is essential for applications where the vehicle is subjected to heavy loads, harsh environments, and long operating hours, such as construction, mining, and long‑haul transport. In these conditions, the rear hub is constantly exposed to extreme loads, vibration, and potential impact damage, which can lead to bearing failure, wheel misalignment, and brake performance issues. The AZ7117451220/21 is engineered to provide long‑lasting structural integrity and reliable performance, ensuring the wheel end remains secure and the vehicle operates safely.
When replacing the rear hub, it is recommended to inspect the wheel bearings, seals, brake drum, and axle shaft for signs of wear or damage. The AZ7117451220/21 is designed to work with the factory components, ensuring proper bearing preload and alignment. It is suitable for both standard and heavy‑duty axle configurations.
For fleets with multiple HOWO trucks, standardizing on the AZ7117451220/21 simplifies axle repair inventory and ensures the correct component is available for scheduled maintenance or emergency repairs. Always verify the vehicle model and axle configuration to confirm compatibility, though the AZ7117451220/21 is the standard rear hub for the majority of T5G applications.
Replacing the AZ7117451220/21 rear hub assembly is a complex procedure that requires mechanical expertise, specialized tools, and a clean work environment. This work should be performed by qualified technicians with experience in heavy‑duty truck axle repair. Begin by safely raising the vehicle and supporting the rear axle on jack stands, then remove the wheels and brake drum.
Remove the old hub by extracting the axle shaft, removing the lock nut and bearing retaining hardware, and carefully sliding the hub off the axle spindle. Inspect the spindle, bearings, and seals for wear or damage. Clean all components thoroughly and replace any worn bearings or seals as needed.
Install the new AZ7117451220/21 hub assembly onto the axle spindle, ensuring the bearings are properly packed with high‑quality grease and the seals are correctly seated. Adjust the bearing preload according to the manufacturer’s specification, then install the lock nut and retaining hardware. Reassemble the brake drum, wheels, and any other removed components.
After installation, check the wheel end for smooth rotation and proper alignment, and verify that the brakes function correctly. Perform a thorough road test to confirm smooth operation. For maintenance, periodically inspect the hub for signs of cracks, corrosion, or bearing play, and repack or replace the bearings as part of a comprehensive axle overhaul to ensure long‑term reliability.
The AZ7117451220/21 rear hub assembly is manufactured in an ISO 9001‑certified facility using advanced casting, heat‑treatment, and CNC machining processes. The cast steel is sourced from certified foundries and undergoes chemical and mechanical testing to ensure it meets GGG‑50 specifications for tensile strength, ductility, and fatigue resistance.
Each casting is radiographically inspected for internal porosity and defects before machining. The CNC machining process maintains tight tolerances on all critical dimensions, including bearing bores, wheel stud holes, and brake drum mounting surfaces. The hub is then phosphate‑coated to provide corrosion resistance and a paint‑ready surface.
Every hub undergoes a final dimensional inspection using CMM equipment, along with a torque‑retention test on the wheel studs. Random samples from each production batch are subjected to dynamic load testing and fatigue cycling to simulate real‑world axle loads, validating long‑term reliability and safety.
