When you're driving and turn a corner, you probably aren't aware of all that's going on with your wheels. The outside wheels have a longer distance to travel than the inside wheels, so there are gears that allow the wheels to go at different speeds when you turn. That set of gears is called a differential. In front-wheel drive vehicles, it's by the transmission and called a transaxle. Rear-wheel drive vehicles have the differential, naturally, on the rear axle. Many all-wheel and four-wheel drives add a center differential since power has to go to the front and rear wheels. (Some newer vehicles power wheels with electric motors, but that's a whole different story.) Time and distance traveled eventually can take their toll on the differential, and you may notice some noises you hadn't heard when your vehicle was newer. Sometimes you'll hear a whir that might change in pitch when you turn. You may hear clicking sounds when you're moving. Others d ... read more

Differential? What's that? And what's it for? I've been told by my service advisor that I need to get it serviced, but is that on the level?Do these questions sound familiar? They're not uncommon for Temecula drivers. A lot of us in Temecula don't know what a differential is or what it's for. Every vehicle has a differential, and, yes, it does need to be serviced. In fact, it's more important to the operation of your vehicle than the air conditioner or windshield wipers.A differential allows your vehicle tires to move at different speeds. This happens more than you think. The best example is when a vehicle is turning. The inside wheel travels a much shorter distance than the outside wheel during a turn. This means the outside wheel has to move faster than the inside wheel. Without a differential, your tires would hop and skip while turning. They would also lose traction in sand or snow.The location of your differential depends on what kind o ... read more

Every vehicle on California roads has a differential, and it is important to the proper operation of the vehicle. But most Temecula residents don't have a clue what it is.The differential compensates for differing wheel speeds. For example, when you turn, the inside tire on the turn travels a much shorter distance than the outside wheel. So the inside wheel of the vehicle must move at a slower speed than the outside wheel. Without a differential, the wheels would hop and scrape while turning.Have you ever seen the large bulge in the middle of the rear axle of a truck? That's the differential. In a rear-wheel drive vehicle, the differential is located on the back axle. Four-wheel drive vehicles and SUV's have differentials on both the front and the rear axle.You might expect that the differential is located on the front axle of a front-wheel drive vehicle. You'd be right. But the differential is called a transaxle on a front-wheel ... read more

When you take a corner in your car, the outside wheels have a slightly longer distance to go than the inside wheels. That means that the outside wheels must turn a bit faster than the inside. The piece of mechanical wizardry that makes this possible is called the differential. The differential allows the drive wheels to rotate at different speeds in turns without the wheels binding or hopping. If you have a rear-wheel drive vehicle, the differential is on the rear axle. You’ve seen that bulge in the middle of the axle when you’re behind a truck – that’s the differential. If you have a front-wheel drive vehicle, the differential function is handled by your transaxle. Of course, all-wheel drive vehicles have differentials on both axles. They also have a center differential or a transfer case between the front and rear axles to compensate for speed differences between the front and rear. Because all the power of the engine is tra ... read more
