Drive Shaft Basics: 101

Carz R’ Us has been seeing an increase of drive shaft issues coming through the shop lately that our clients are unaware of, which is why our courtesy inspections are important during every service that we provide. Recently, we had a Saturn Vue come into our shop for an oil change. During our courtesy inspection, we noticed that the drive shaft was extremely loose, causing a potential hazard on the road.

So, what exactly is a drive shaft? The drive shaft, sometimes referred to as a propeller shaft, is a hollow steel component underneath the vehicle that transmits torque and rotation from the engine to the wheels. They are most commonly found on vehicles that have rear-wheel drive and 4-wheel drive. The drive shaft consists of a few components, such as tube shafts, yokes, and U-joints. These components are illustrated in the diagram below:

The most common symptoms of a drive shaft problem include vibrations and noises coming from underneath the car. Some of the noises it may make include scraping, rattling, or even a clunking sound. If the vehicle has any of those symptoms, take it to an auto repair shop immediately. We have included a link to our YouTube video below of the Saturn Vue that had a very loose drive shaft. Fixing this issue is critical and Carz R’ Us is committed in making sure all of our clients are back on the road safely. On average, a drive shaft lasts approximately 75,000 miles so it should be checked regularly.
