The differential side gear is a crucial component within the axle assembly, enabling torque transfer to the wheels while allowing them to rotate at different speeds during turns. Its robust design ensures durability under heavy loads and high torque conditions typical in heavy-duty trucks. Proper functioning of this gear is essential for maintaining traction and vehicle stability, especially on uneven terrain or during sharp maneuvers. Regular inspection and replacement prevent differential failure, which can lead to costly repairs and safety issues. This part is fundamental for smooth power distribution and optimal drivetrain performance.
