San Diego Auto Repair

One automotive service issue that doesn't get much attention is driveline service. Drivelines don't get talked about very much around San Diego, 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 we 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 over simplify a bit. Let's start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both t ... read more

With front-wheel drive being so common these days in San Diego, CA, the differential is just taken care of during a transmission service, so most folks in San Diego, CA 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 mind for our San Diego customers. So it's not uncommon for people to not know they have a differential let alone know that it needs service. To better understand what a differential does, think about our local San Diego high school track. 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 runner has the same distance to run. The differential compensates for the difference in speeds between the ins ... read more

Here at Convoy Auto Repair, we have viewers, like you, from all across the country 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 your differential needs service, or seen it as an option up on the service menu. Differential 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. Differentials have gears in them that transfer the power from the drive train to your wheels - which is why they're often referred to as gear ... read more

Don’t be embarrassed if you don’t know what a differential is; you will in a moment. That fact is that if you drive a car, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. You might even have two or three. As you might guess from the name, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner. Your inside wheel has a shorter distance to travel than the outside wheel as you go around 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. Without a differential, our tires would scrub and hop along the pavement during turns. You’ve probably noticed the big bugle in the middle of the rear axle when you’re behind a truck. That’s the differential. Rear-wheel drive vehicles have ... read more
