![]() Rear-wheel-drive cars have a long driveshaft that’s connected to the differential and transmission, while four- and all-wheel-drive cars contain two or more driveshafts. The driveshaft location varies based on what type of vehicle you drive. With a front-wheel-drive vehicle, there is a transaxle instead. Most driveshaft assemblies include yokes, slip splines, universal joints, a propeller shaft and various bearings.Ī traditional driveshaft can only be found on rear- and four-wheel-drive models. The shaft assembly itself is flexible so the axles can travel up and down with lateral movement during acceleration and braking. It is responsible for transmitting the torque at different angles among the various driveline parts. It’s a rod-like part that basically drives your car. The driveshaft converts the torque from our car engine into movement that propels the wheels. Because this is a serious safety matter, you will want to have it looked at right away. ![]() ![]() When the driveshaft becomes damaged, the wheels cannot turn properly, which limits your control over the car. If you are having trouble when taking a turn, it could indicate that the driveshaft is on its way out. While the driveshaft is responsible for converting torque into movement, it also affects the turning of your vehicle. It could also be accompanied by some of the sounds I previously discussed. Sometimes this is caused by a loose U-joint or a worn-out center bearing. As you accelerate from a stopped position or to increase speed, you might notice a significant increase in the shuddering when the drivetrain is defective. While I talked about some vibration, shuddering is much more noticeable. These sounds indicate that the CV joint is worn out and about to fail. However, you might also notice a knocking or clicking noise. This is an easy fix that only requires some grease. This causes all kinds of sounds that can be heard from your vehicle.įor example, squeaking while traveling at low speeds could indicate that the U-joint doesn’t have enough lubrication. When bushings and bearings begin to go bad, the driveshaft has trouble rotating normally. There are some other sounds a defective drivetrain can make. Whatever the cause, you should always have it looked at. In some cases, the clunking could just be a worn-out U-joint. You may notice this type of sound more frequently when shifting. If you hear clunking noises, it could be a sign that there’s a problem with the driveshaft. Allowing the drivetrain to continue vibrating will lead to damage of other vital components. Other times, it could be related to the driveshaft not being properly bolted in place or if it is out of balance. Sometimes the vibration is caused by failing U-joints or bushings. As time goes on, this vibration could become worse. When the driveshaft begins to fail, it’s common to feel some vibration. Here is a more detailed list of the signs of a bad or failing driveshaft to look for. Other noises like squeaking, clicking, or knocking are also common. You may also notice clunking noises coming from under the car when releasing the throttle. The most common symptom of a bad driveshaft is vibrations when accelerating or driving at high speeds.
