Differential Service at Davis Automotive Repair

Here at AutoNetTV, we have national viewers, like your neighbors in Centennial, who write to us with questions or feedback. One common question we're asked is: "What is a differential and what does it do?" You may have been told by your Davis Automotive Repair service advisor that your differential needs serviced, or it's seen it as an option up on the service menu. Differential service at Davis Automotive Repair covers a lot of things, so let's first talk about what a differential does.As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow o ... read more

Time for Differential Service at Davis Automotive Repair?

Hello Centennial - let's talk differentials. If you have a rear-wheel drive vehicle, your differential is on the back axle. With front-wheel drive cars, the differential is up front. All-wheel drive and 4-wheel drive vehicles have three differentials - front, rear and in the middle. So you see, you've got a differential (or two or three) and it needs service now and then.What does your vehicle differential do? Well, it compensates for the differences in speed between your outer and inner wheels in a turn. Using the dimensions of a typical car, let's compare the distance the wheels travel from the start of a turn through to the completion of the turn.The inside wheel travels about 12.6 feet/3.8 meters. How much farther does the outside wheel travel? About 18.8 feet/5.7 meters – over 6 feet/1.9 meters more. This means the outer tire has to rotate 9 times in the same amount of time that the inner tire has to rotate only 6 times - so the ... read more

Drive Train Service in Centennial at Davis Automotive Repair

The drive train in your vehicle includes all the components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.Let's start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.Davis Automotive Repair service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking n ... read more

Differential Service in Centennial, Colorado - What You Need to Know

Scratching your head? Don't worry, if you don't know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Centennial, Colorado, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some Centennial vehicles might even have two or three.Not surprisingly, a differential's job is to compensate for differences; specifically, they're the differences in wheel speed when turning. For instance, imagine taking a corner near your Centennial, Colorado, home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, Centennial residents' tires would scrub and hop along the pavement during turns like the early car ... read more

One Centennial automotive service issue that doesn't get much attention is driveline service. Drivelines don't get talked about very much around Centennial, but they're very important. First let's define what the driveline is:Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.That's not really a lot of components, but they handle the full force of the engine. Without the driveline you're not moving. So Centennial residents need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive.
