What exactly is the differential of a truck?

Every commercial vehicle or a truck has a differential in it. Some are built into the transaxle while others are separate components that connect the transmission output to the drive wheels.

When your truck is making a turn at a corner, the wheels on the outside of the turn drive farther and rotate faster than the wheels on the inside. This is where a differential comes into play. It is what allows the drive wheels to turn at different speeds while still supplying torque to the wheels.

In order to achieve this, the differential makes use of a series of gears which rotate in sync with one another while still transmitting power. The differential inside your truck is what enables your truck to drive around a curve without the tires skipping and sliding along the road.

The differential is an integral and important part of your truck’s drivetrain. The drivetrain of your truck works along with the engine to get the wheels moving. It works in sync with the transmission and facilitates the turning of your truck's left and right wheels at different speeds during turns. The differential is located between two wheels and attached to each wheel by an axle shaft.

Transmission mainshaft broken

We got this truck towed in due to transmission not going into gear. Drained some oil and found metal pieces in oil. We removed transmission from truck, opened top cover of this 9-Speed Transmission. We removed rear section and found a main shaft on this rear section broke right before synchronizer assembly. We quoted repair and a reman weller transmission.

After seeing number customer decided to replace broken parts in transmission. We had to order parts overnight, we overhauled transmission. Jorge Lopez, owner, has overhauled 1,000's of transmission over more then 40 years working on commercial vehicles. Before we installed transmission, we always check rear main seal, clutch, and fuel lines at back of engine.

We removed and checked clutch, clutch was in good shape so we put it back on. After installion of transmission, Jorge, owner goes to test drive. Jorge was over the road for 20 years so he knows exactly what to check during a test drive. We do a clutch adjustment and get this truck driver ready to get back to work delivering fuel through all of South Texas.
