Time for Differential Service at Phil's Pro Auto Service?

Hello Greeley - 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 ou ... read more

Differential Service in Greeley, 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 Greeley, Colorado, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some Greeley 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 Greeley, 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, Greeley residents' tires would scrub and hop along the pavement during turns like the early cars.Ever notic ... read more

Drive Train - What You Need to Know in Greeley

One Greeley automotive service issue that doesn't get much attention is driveline service. Drivelines don't get talked about very much around Greeley, 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 Greeley 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. For purposes of our discussion, we're going to have to oversimplify a bit. If you are ready to have your drive train looked at, give us a call at 970-353-2739. Let's start with front wheel drive. The point where the tran ... read more

Differential Service at Phil's Pro Auto Service

Here at AutoNetTV, we have national viewers, like your neighbors in Greeley, 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 Phil's Pro Auto Service service advisor that your differential needs serviced, or it's seen it as an option up on the service menu. Differential service at Phil's Pro Auto Service 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 on G ... read more

Drive Train Service in Greeley at Phil's Pro Auto Service

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.Phil's Pro Auto Service 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

Vive la Differential at Phil's Pro Auto Service in Greeley

There are a lot of drivers in Greeley who are due for a differential service, but had never heard of a differential before.With front-wheel drive being so common in Colorado these days, the differential is just taken care of during a transmission service, so most Greeley folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in Greeley to not know they have a differential, let alone know that it needs service.To better understand what a differential does, think about a track at any Colorado high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each run ... read more
