What does a locking differential do?

A locking differential is a crucial component in vehicles, particularly in off-road and performance contexts. Its primary function is to lock the left and right axle together, which ensures that the power is distributed equally to each drive wheel. This is especially beneficial in situations where one wheel might lose traction—such as driving on mud, ice, or uneven surfaces—because the locked differential enables both wheels to turn at the same speed, thereby improving traction and stability.

This is why the option referring to the locking of the left and right axles to provide equal power to each drive wheel is correct. By doing so, the locking differential effectively enhances the vehicle's ability to navigate challenging terrains and improves its overall traction when needed most.

Other options, while they suggest relevant concepts, do not accurately describe the core function of a locking differential. For instance, allowing for different wheel speeds is characteristic of an open differential, which is the opposite of what a locking differential does. Similarly, while a locking differential can assist in preventing slippage by evenly distributing power, its primary role is about equal power distribution between wheels rather than specifically preventing slippage alone. Lastly, the claim that it transfers power only to the rear wheels is irrelevant, as locking differentials can be found in both
