Rear Differential Gear Spider
Mitsubishi FUSO®

The Rear Differential Gear Spider, also known as the differential pinion gear, is a vital component of a commercial truck's drivetrain system. This part is responsible for transmitting power from the driveshaft to the rear wheels, allowing the truck to move forward. The Rear Differential Gear Spider is made up of a series of small gears that mesh together to create a gear ratio that determines the speed and torque of the truck's wheels. Without a properly functioning Rear Differential Gear Spider, a commercial truck would be unable to move forward. This part is subject to wear and tear over time, and it is important to regularly inspect and replace it as needed to ensure the continued safe and efficient operation of the vehicle. If you notice any unusual noises or vibrations coming from the rear of your truck, it may be a sign that the Rear Differential Gear Spider needs to be replaced.
