The transfer of torque from the truck's transmission to the axle and wheels while constantly adjusting to differing speeds and angles places an extreme amount of stress on driveline components. When you make a turn, the outside wheels travel farther than the inside wheels, and while the difference may be relatively small, it can add up and damage your vehicle if it isn't offset.
Your differential makes up for this difference by mechanically transferring torque through a set of gears that keeps the engine and transmission load steady regardless of how sharp your truck turns. Unfortunately, the extreme loads placed on your differential can lead to excess heat and wear.
The differential is coated with thick gear oil to reduce friction and wear and protect it from damage. Typically, differential fluid is changed every 30,000 to 60,000 miles, but if you are hauling heavy loads or diving in stop-and-go traffic, we recommend more frequent service.
