How to Identify Ford Explorer Differential Codes
If you own a Ford Explorer, you may want to know what kind of differential you have in your rear axle. The differential is the part of the drivetrain that allows the wheels to rotate at different speeds when turning. There are different types of differentials, such as open, limited-slip, or locking, that have different advantages and disadvantages depending on the driving conditions.
One way to find out what kind of differential you have is to look at the axle tag that is attached to the rear axle cover. The axle tag has a series of numbers and letters that indicate the model, ratio, and type of differential. For example, an axle tag that reads S614E 73 88 9K21 means that the axle is a Ford 8.8-inch model with a 3.73 gear ratio and a limited-slip differential. The S614E is the model code, the 73 is the ratio code, the 88 is the ring gear size in millimeters, and the 9K21 is the date code (October 21, 1999).
However, not all axle tags are easy to read or present on the axle. Sometimes they may be missing, damaged, or painted over. In that case, you can use other methods to identify your differential type. One method is to jack up the rear of the vehicle and spin one wheel by hand. If the other wheel spins in the same direction, you have a limited-slip or locking differential. If it spins in the opposite direction, you have an open differential. Another method is to check the door sticker on the driver's side door jamb. The door sticker has a series of codes that indicate various specifications of your vehicle, including the axle code. The axle code is a two-digit number or letter that corresponds to a specific differential type and ratio. You can use a Ford axle code chart to decode your axle code and find out what kind of differential you have.
Knowing your Ford Explorer differential codes can help you when you need to replace or upgrade your differential parts, such as gears, bearings, seals, or clutches. It can also help you choose the right oil and additives for your differential maintenance. Moreover, it can help you optimize your vehicle's performance and handling by selecting the best differential type for your driving style and needs.
In this article, we will discuss some of the common types of differentials that are found in Ford Explorer models and their features and benefits. We will also provide some tips on how to choose the best differential for your Ford Explorer based on your driving needs and preferences.
An open differential is the simplest and most common type of differential that allows the wheels to spin at different speeds when turning. However, an open differential also has a major drawback: it sends power to the wheel with the least traction, which can cause loss of traction and control in slippery or uneven surfaces. An open differential is suitable for normal driving conditions on paved roads, but not for off-road or performance driving.
A limited-slip differential (LSD) is a type of differential that limits the amount of slip between the wheels when one wheel loses traction. It does this by using clutches, gears, or viscous fluids to transfer some torque from the spinning wheel to the non-spinning wheel, thus increasing traction and stability. A limited-slip differential is ideal for driving on wet, snowy, or icy roads, as well as for improving cornering and acceleration performance.
A locking differential (locker) is a type of differential that locks the wheels together when needed, creating a 50/50 torque split between the axles. This provides maximum traction and grip on rough or slippery terrain, such as mud, sand, or rocks. However, a locking differential also makes turning difficult and can cause tire wear and drivetrain stress on paved roads. A locking differential is best for off-road or extreme driving situations where traction is more important than handling. aa16f39245
