Signs My Driveshaft Is Going Bad

The driveshaft is a crucial part of the drivetrain. The drive train consists of numerous parts, including the transmission, wheels, and driveshaft. Without the driveshaft, the wheels on your automobile would not turn. Generally, it is recommended that you have the drive train inspected annually. This allows us to lubricate the driveshaft and replace any worn parts. If your driveshaft is overdue for service, parts of it could go bad. Let’s talk more about this below.

Vibrating or Shuddering

A driveshaft that is overdue for service may start to vibrate underneath your automobile intensely. You will feel the vibration underneath you. This can be a sign that there is a problem with one or more of the driveshaft parts. For example, the driveshaft will vibrate if the bushings are worn out. It will also vibrate if the universal joint is worn out. As an aside, this part is commonly known as the U-joint.

A worn U-joint can also make the driveshaft vibrate when you press down on the accelerator. It may feel as if your automobile is going to stall. Another thing that will make your vehicle shudder when you press down on the accelerator is worn center bearings. These are also parts in the driveshaft that need attention when they get too old. They need to be replaced if they are wearing out.

Driveshaft Noises

The driveshaft can also make noise, and the most common reason why it will start making noise is that it needs to be lubricated. The driveshaft also has fluid inside of it that needs to be changed. If the driveshaft is overdue for lubrication, it will start to squeak, especially when you are driving on rough roads. The parts that require lubrication are the bearings and the U-joint.

We talked above how the driveshaft will vibrate if the U-joint is worn out. Usually, the vibration is caused because the joint is loose. In addition to vibration, the driveshaft will also clunk if the U-joint needs to be replaced. This sound means that the joint is at the end of its lifespan. In other words, it is badly worn and needs to be replaced as soon as possible to avoid driveshaft damage.

Finally, dry or worn driveshaft parts can also make rattling noises in the driveshaft. In some cases, you may also hear scraping. It is important to have any strange noise coming from underneath your automobile inspected right away to avoid additional and costly damage. We can do that here at our shop.
