What Does “Remanufactured” Mean?

Finally, we put the differential back together and it’s ready to go into your vehicle

Common Questions About Remanufactured Differentials

How Does A Differential Work?

A differential allows two wheels on the same axis to rotate at different speeds. This is essential to turning, in which the outer wheel will need to rotate more quickly than the inner wheel. This is because in a turn, the wheel on the outside travels a greater distance than the inside wheel. Different kinds of differentials, as explained below, have their own advantages and disadvantages.


What is an Open Differential?

An open differential is sometimes also known as a standard differential. The open differential has the benefit of being more affordable and less complex. Unlike a limited slip differential, if two wheels experience different levels of traction, an open differential will send power to the wheel with the least traction. For driving on roads and stable surfaces, an open differential is enough.


What is a Limited Slip Differential?

A limited slip differential, unlike an open differential, is able to prevent excessive power from being distributed to a slipping wheel that has lost traction due to snow, dirt, or other off-road conditions while the contacting wheel remains stationary. The limited slip differential handles situations where only one of the wheels has lost traction better than an open differential, making it the ideal choice for off-roaders.


What is a Locking Differential?

A locking differential is like a limited slip differential. It also has advantages over an open differential for off-road environments. Locking differentials are more durable than limited slip differentials, require no servicing, and provide excellent traction. Their downside is that they wear out tires more quickly and sometimes audibly clank or bang from the automatic lockers.


What is Differential Fluid?

Just like engine oil, differential fluid lubricates the gears inside the differential, reducing friction and keeping everything inside your differential healthy. Fortunately, differential fluid does not need to be changed as frequently as engine oil. Most vehicles need differential fluids changed every 30,000 to 50,000 miles but be sure to check your vehicle’s manual to be sure.
