Not a Good Vibe (Driveshaft Failure)

When you feel your vehicle vibrating as you're driving down the road, one cause could be something you may not have ever seen: your driveshaft.  It is underneath the vehicle and most drivers don't climb under there to take a look very often.  The driveshaft is a cylindrical part that helps conduct the rotational power from your engine to your drive wheels.  If you have a four-wheel drive vehicle, you may have two driveshafts.  The drive shaft has bushings, and when they wear out, that's a likely source of the vibrations.  When the bushings are in good condition, they prevent the driveshaft from vibrating.  And if you don't get your vehicle repaired fairly soon after discovering vibrations, they'll continue to get worse and cause other components of the drivetrain to wear out. The driveshaft is, of course, only one part of the drivetrain.  It includes other parts such as axles, transmission, differentials and joints.  They all work together and ne ... read more

Drive Train Service in San Diego at Pacific Highway Auto 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.Pacific Highway Auto 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 click ... read more

Differential Service at Pacific Highway Auto Repair

Here at AutoNetTV, we have national viewers, like your neighbors in San Diego, 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 Pacific Highway Auto Repair service advisor that your differential needs serviced, or it's seen it as an option up on the service menu. Differential service at Pacific Highway Auto 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 o ... read more

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

What Is a Differential and Do You Have One?

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 San Diego drivers 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 San Diego customers' minds. It's not uncommon for drivers to not know they have a differential let alone know that it needs service. Call Pacific Highway Auto Repair in San Diego at 619-299-7700 for information about differential service, or stop by our San Diego, CA, auto center at 4306 Pacific Highway, 92110. To better understand what a differential does, think about our local San Diego high school track. There are lanes marked off on the track.
