The differential is a device that splits the engine torque two ways, allowing each wheel to spin at a different output speed.

The differential has a few primary jobs:
- To aim the engine power at the wheels.
- To act as the final gear reduction in the vehicle, slowing down the rotational speed of the transmission one more time before it hits the wheels.
- To transmit the power to the wheels while allowing them to rotate at different speeds.
A lot of damage to differentials is caused by being stuck and spinning one wheel for an extended period trying to get unstuck. If one wheel is on good traction and not turning, the wheel on poor traction is spinning at 200% which puts undo stress, wear and heat on the pinions and serious damage can result.

   Benefits of differential repair.

Whether your car or truck has four-wheel drive, front wheel drive, or rear wheel drive, your vehicle has a differential that experiences heavy wear and tear. When scheduling a differential repair service, you should consider where you drive most often and how much time your vehicle spends traversing particular types of terrain. Tougher terrain, like dirt roads, unpaved or gravel roads can have a heavier impact on the life of your vehicle’s differential. Overall differential maintenance can vary from vehicle to vehicle, but you should always be aware of the warning signs of problems pertaining to your differential. 

You might notice a strange noise as one of the first warning signs. The most common noise is a steady whining or grinding that increases with vehicle speed - that usually indicates problems with the bearings or gears. A rhythmic banging or clunking around corners can also be indicative of impending failure. 

Oil leaking from the seals is also something you want to take care of before the fluid gets low enough to cause major problems. A differential fluid change can positively impact the safety and health of your vehicle. A bad differential could cause serious and expensive damage to other components on your vehicle such as your transmission, not to mention also creating an unsafe driving condition.
