How do diffs work?

Simply put, a differential is a system that transmits an engine’s torque to the wheels. The differential takes the power from the engine and splits it, allowing the wheels to spin at different speeds. Turn it around a corner and you’ll have no issues, as each wheel is able to turn independently from the other.

How does a front differential work?

When 4WD is engaged, the transfer case splits the torque 50/50 between the front and rear drive shafts. The front drive shaft spins at the same speed as the rear drive shaft, transferring torque to the front differential. The front differential then transfers that power to the front wheels by way of the axle shafts.

How does a differential break?

The first and most common is loss of differential oil which can cause gears inside the differential housing to break, grind, or even block the rear wheels. Also, it is known that differentials can break if the inside gears are made of softer-type steel which is not able to withstand engine power and torque.

Can a bad differential cause transmission problems?

When the differential doesn’t perform well, it creates metal-on-metal friction that wears down surfaces. The resulting heat weakens gears and can cause component failure and transmission problems. A bad differential makes the car harder to control turning corners, and that can be dangerous.

When would you use a diff lock?

How to Use Your Diff Lock When Driving. First, a diff lock should not be engaged for on road driving, unless weather conditions such as snow or ice mean that extra traction is required. Use your locking differential when you want to go off road, for driving on difficult terrain, such as dirt, gravel, mud or snow.

Should my front drive shaft spin in 2wd?

No, your front driveshaft will not spin freely in 2wd. Your front axle and driveshaft are always locked and spinning when your vehicle is moving.

What happens if you don’t change your differential fluid?

If this fluid isn’t changed in the manufacturer-prescribed intervals, then it can get dirty and thick, which could damage the differential over time.

How does a differential work in a car?

Working of a differential is explained in a logical and illustrative manner in this animated video. Differential helps in turning the drive wheels at different rpm while the vehicle takes a turn. The basic parts of a differential is introduced first. After that working of differential at various driving condition is…
