Many types of heavy machinery, vehicles, and construction equipment rely on driveshafts to deliver power from a motor to the gears. These vital components are in almost constant motion, so they will wear out over time. Here are a few of the most common causes of breakdowns and signs that you may need driveshaft repairs.

What Are the Common Symptoms of Driveshaft Problems?

1. Excessive Vibrations

Driveshafts must be perfectly balanced to minimize side-to-side vibration when rotating at high speeds. If the driveshaft is damaged or the bushings holding the part in place wear out, you might notice excessive vibrations that cause the entire machine to shake.

If the issue isn’t corrected, these vibrations will only get worse until the driveshaft fails entirely. This can cause serious damage and may even destroy the machine, so it’s best to have vibrations looked at by a professional immediately.

2. Clunking Sounds

A small tube runs through the middle of the driveshaft, allowing it to spin freely. These parts normally don’t wear out, but excessive pressure or an overloaded machine can cause permanent damage to the tube.

If the tube needs to be repaired, you might hear strange clunking or scraping sounds, especially when the machine changes speeds. A machine with a damaged tube may be unsafe to operate, even if the driveshaft appears to be intact.

3. Loud Banging or Clanging Noises

Worn-out bushings or U-joints holding the driveshaft in place could allow the entire assembly to come loose. A loose driveshaft may eventually fall out of the machine or come flying off while it’s in operation.

In many cases, a driveshaft repair professional may be able to replace worn-out bearings, which prevents further damage. However, if the component is rattling for too long, it may be damaged or get thrown out of balance. When this happens, you may need to repair or replace the driveshaft itself.
