Product Introduction

The 3433501023 / 3433500723 Differential Assembly is a complete drivetrain component designed for Mercedes-Benz and MAN heavy-duty trucks. It is installed inside the drive axle housing and works together with the crown wheel, pinion gear, side gears, planetary gears, differential spider, and bearings to transfer power from the drivetrain to the wheels.

The differential assembly plays a critical role in vehicle operation by distributing torque between the left and right axle shafts while allowing both wheels to rotate at different speeds during cornering. This function reduces tire wear, improves vehicle handling, and ensures smooth power transmission.

During long-term heavy-load transportation, differential components are exposed to high torque, impact loads, and continuous rotation. Gear wear, bearing damage, insufficient lubrication, or internal clearance changes may lead to abnormal noise, vibration, overheating, and reduced driving efficiency.

The 3433501023 / 3433500723 differential assembly provides a complete replacement solution for worn or damaged differential systems. Compared with replacing individual internal components, a complete assembly ensures better gear matching, easier installation, and improved operational reliability.

Manufactured according to OEM specifications, this differential assembly uses high-strength alloy steel components with precision machining and heat treatment processes. The optimized gear tooth design provides excellent strength, smooth engagement, and stable torque transmission performance.

It is widely used for axle repair, differential overhaul, fleet maintenance, and aftermarket replacement applications for Mercedes-Benz Actros, Axor, NG, SK, Econic, North Benz, and MAN truck models.

Each differential assembly undergoes strict quality inspection including gear accuracy testing, hardness inspection, backlash adjustment verification, dimensional measurement, and assembly performance testing to ensure dependable operation and extended service life.
