3 Causes of Driveshaft Noise (When Turning, Braking, and Reversing)
If you hear a loud rattling or whistling noise under your car, it often indicates a problem with your driveshaft. This important component transfers power from the transmission to the wheels, so the noise indicates a potentially serious problem.
But what exactly is causing this annoying driveshaft noise? Should you be worried? Learn about the most common causes of driveshaft noise and how much it can cost to replace it.
3 Most Common Causes of Driveshaft Noise
A subtle problem with your driveshaft can cause these noises when braking, reversing, or turning. To learn more about the different causes, here are the three most common reasons why you might hear noises coming from your driveshaft:
#1 – Bad Bearings or Bushings
The driveshaft is supported by bearings or bushings. They connect the different parts of the driveshaft together and provide support. The inside is usually made of rubber to provide extra support. If you have bad bearings or bushings, the increased vibration intensity will cause the driveshaft to make noises.
#2 – Bad Universal Joint
Universal joints are responsible for connecting rigid rods with two inclined axes. When these joints become damaged, fail, or wear out from excessive use, the driveshaft will stop spinning as well. You will then hear all sorts of unusual noises, such as: B. Scratching, rattling, or even a clattering from the slip fork.
#3 – Dislocated Driveshaft
If you retard a universal joint too much, the entire driveshaft can twist and actually fall onto the pavement while driving. When this happens, no power is transmitted to the wheels and you can’t drive. Before it dislocates, the noise you hear when turning or braking will be much louder.
This is a sign that the driveshaft needs to be replaced before it comes completely out of the assembly.
