![]() ![]() This makes an open differential less than ideal on slippery roads. ![]() It does allow the wheels to turn at different speeds, but it cannot limit power if one loses traction while the other doesn’t. This is the most basic type of diff, meaning it’s also the most affordable. What Are The Different Types Of Differentials? Open Differential Simply put, the diff takes that power and then splits it between each of the wheels, allowing them to rotate at different speeds.įor an in-depth look at how this process works, check out this video. Power is supplied from the engine via the transmission to a driveshaft connected to the differential. If this wasn’t possible, the handling of your car would be unpredictable and dangerous. Since each has a different length, they need to be able to rotate at different speeds. Similar to runners on a track, when turning your vehicle, each wheel travels down a different path. What Is A Rear Diff, And How Does It Work? Note: for the sake of syllable count, we’ll often refer to the differential as “diff” (you’re welcome!). ![]() Thankfully, this short guide will cover everything you need to know about rear differentials, including what they are, how they work, and what types there are.Īfterward, we will review the symptoms that suggest yours is failing and what the repair options are.įinally, we will examine in detail the exact costs of repairing or replacing a rear differential. Ignoring a faulty differential can not only cause further damage but can be dangerous as well. If replacing a gasket or bearing or sealing any problem areas isn’t possible, you will likely spend between $1,500 to $4,000. How much do rear-differential replacements cost? This component is not only a mouthful, but it’s also the part of your drivetrain that allows the wheels to turn at different speeds.ĭoes that sound important? Well, it definitely is! The only thing higher than the number of letters in the word “differential” is the amount you’ll spend to replace one. ![]()
