Welded differentials are the exact opposite of all other differentials.This type of differential can divert up to 100% of the engine’s power to an individual wheel, allowing for better traction in almost any condition. Torque vectoring is similar to electronic LSDs, but takes it further by utilizing more sensors and computing power.Whereas locking differential usually requires driver input to lock. They’re similar to locking differentials, but they’re more dynamic. But the main idea behind all of them is to lock the wheels to limit slip and allow for better traction. Limited-slip differentials (LSD) have several variations.This is great for offroading and getting a stuck car out. Locking differentials are largely similar to an open differential, but it has the ability to lock the wheels together and force them to spin at the same rate regardless of the condition.Let’s briefly discuss the different types of differential: Speaking of differential types: Other Types Of Differential Most carmakers specify that you should change your differential fluid every 50,000 miles or so. Regardless of the type you have, they all work by using a set of gears and they all need lubrication. The video above should give you a better idea of how the system works. When it detects the car is going through a corner, the spider gear will allow the outside wheels to spin faster. This sort of differential works by using spider gear. There are several types of differential, but most “normal” cars usually have an open differential. If they can’t rotate faster, the outside wheel will have to slip to keep up with the inside wheel which is not pleasant and can wear out the tires and other components quickly. The outside wheel will have to cover a longer distance. This is necessary since the outside wheel will have to rotate faster than the inside wheel since it has to travel a further distance.įor example, if you’re turning right, then the left wheels are the outside wheels and the right wheels are the inside wheels. As mentioned, their purpose is to allow the driven wheels to rotate at different speeds during cornering. The differential is a set of gears inside a round housing usually made from carbon steel.Įvery car has a differential for its drive wheels, including front-wheel drive cars. This will give you an idea of why it needs maintenance, and why you should care for it. Final Thoughts How Does A Differential Workīefore we discuss differential fluid change itself, let’s understand the basics of differentials first and why they’re important.Here’s everything you need to know about differential fluid change: Whether it’s due to age or due to a leak, oil and other lubricants need changing at some point. Differential fluid or oil will eventually lose its lubricity. So, is a differential fluid change necessary? This ensures they don’t wear out quickly and keep the temperature in check. As with any other set of gears in your car, it needs lubrication to minimize friction. The differential is a set of gears that allow the drive wheels to rotate at different speeds.
