Manufactured from high-quality alloy steel with precision-ground bearing surfaces, hardened cross-shaped trunnions, and durable needle bearings, these universal joints withstand the extreme torque loads, high rotational speeds, and demanding operating conditions typical of heavy-duty truck applications.
The 70X178+57X144 universal joints are essential components for maintaining driveline integrity and smooth power delivery. Worn or damaged universal joints can lead to vibration, driveline noise, and catastrophic failure. This genuine OEM set restores smooth, reliable driveline operation and ensures your HOWO truck performs at its best.
Complete front & rear set • High-strength alloy steel • Precision-ground bearing surfaces • Heavy-duty needle bearings • Easy installation
The 70X178+57X144 is a complete set of universal joints designed for the front and rear drive shafts of SINOTRUK Howo A7, T7H, and other heavy-duty truck models. These universal joints, also known as U-joints or cardan joints, are critical components of the driveline, transmitting torque from the transmission to the drive axles while accommodating angular misalignment and driveline movement. Their OEM-grade construction precisely matches the original components’ dimensions, bearing sizes, and material specifications, ensuring a perfect fit and seamless integration with the truck’s existing driveline system.
Each universal joint is manufactured from high-quality alloy steel with precision-ground bearing surfaces and a hardened cross-shaped trunnion. The trunnion is supported by heavy-duty needle bearings that provide low-friction rotation and excellent load-carrying capacity. The bearings are sealed with durable rubber boots that retain lubrication and protect against moisture, dirt, and road contaminants. The joints are precision-machined to ensure proper fit with the drive shaft yokes and are balanced to minimize vibration during operation.
The 70X178+57X144 set includes all the universal joints required for both front and rear drive shafts, providing a complete solution for driveline maintenance or repair. The robust construction and precise fitment of these joints contribute to smooth power delivery, reduced vibration, and extended driveline life. Their corrosion-resistant coating protects against the harsh under-chassis environment.
Common symptoms of failing universal joints include clunking or clicking noises during gear changes, vibration at certain speeds, and excessive play in the driveline. Replacing worn joints with the 70X178+57X144 set restores smooth, quiet driveline operation and protects the transmission and differential from costly damage.
Whether you’re performing scheduled maintenance or addressing a driveline issue, this set offers the quality, precision, and reliability that SINOTRUK Howo professionals demand.
The 70X178+57X144 universal joint set is specifically designed for SINOTRUK Howo A7 and T7H series trucks, as well as other heavy-duty models equipped with similar driveline configurations. It serves as a direct replacement for the original universal joints and is compatible with all drivelines that use this specific joint size and bearing specification.
These universal joints are essential for applications involving heavy loads, frequent gear changes, and demanding operating conditions, such as long-haul transport, construction, mining, and heavy hauling. In these environments, the universal joints are subjected to extreme torque, angular misalignment, and vibration. The 70X178+57X144 set is engineered to provide consistent, reliable power transmission, reducing driveline wear and preventing unexpected failures.
When replacing universal joints, it is important to inspect the drive shaft yokes and slip splines for wear or damage. The 70X178+57X144 set is designed to work with the factory yokes and hardware, ensuring proper fit and balance. It is compatible with both standard and heavy-duty driveline configurations.
For fleets with multiple HOWO trucks, this set standardizes driveline maintenance, simplifying parts inventory and ensuring the correct components are available for scheduled service or emergency repairs. Always verify the joint size and yoke type on your specific truck to confirm compatibility, though the 70X178+57X144 is the standard universal joint set for the majority of A7 and T7H applications.
Replacing the 70X178+57X144 universal joints is a moderately complex procedure that requires mechanical expertise and the proper tools. This work should be performed by qualified technicians with experience in heavy-duty truck driveline systems. Begin by safely raising the vehicle and removing the drive shaft from the vehicle, taking care to support the shaft properly.
Remove the old universal joints using a press or a universal joint removal tool, taking care not to damage the yoke bores. Thoroughly clean the yoke bores and inspect them for wear, scoring, or damage. If the yokes are worn beyond tolerance, they should be repaired or replaced before installing the new joints.
Install the new universal joints from the 70X178+57X144 set, ensuring they are correctly oriented and fully seated in the yoke bores. Apply a high-quality lithium-based grease to the needle bearings and trunnions during assembly. Secure the bearing caps with the retaining clips or snap rings, ensuring they are properly engaged.
Reinstall the drive shaft, torqueing the yoke bolts to the manufacturer’s specification. Mark the drive shaft orientation to ensure proper balance during reinstallation. Conduct a road test to verify that the driveline operates smoothly and quietly, with no vibration or clunking noises. For maintenance, regularly inspect the universal joints for signs of wear, play, or grease leakage. Lubricate the joints at the manufacturer’s recommended intervals using the grease fittings (if equipped) to ensure long service life.
The 70X178+57X144 universal joints are manufactured in an ISO 9001-certified facility using advanced machining, heat-treatment, and quality control processes. The alloy steel is sourced from certified mills and undergoes chemical analysis to confirm its composition and mechanical properties. Each component is machined to exacting tolerances to ensure consistent fit and performance.
Every universal joint undergoes comprehensive quality testing, including dimensional verification, hardness testing, and bearing surface inspection. The needle bearings are tested for hardness and roundness, and the trunnions are inspected for proper heat treatment. Random samples from each production batch are subjected to torque testing and fatigue testing to confirm long-term reliability.
We back the 70X178+57X144 with a comprehensive 12-month warranty against material and workmanship defects.
