Driveshaft Vibration Causes in Heavy Trucks

A vibrating driveshaft is a serious driveline warning sign. It can affect stability, safety, and transmission performance.

Symptoms

• Vibration at certain speeds

• Shaking under acceleration

• Noise from under vehicle

• Increased cabin vibration

Worn Universal Joints (U-Joints)

One of the most common causes.

• Causes uneven rotation

• Leads to vibration under load

Imbalanced Driveshaft

If the shaft is not balanced:

• Vibration increases with speed

• Steering instability may occur

Worn Centre Bearing

In multi-piece shafts:

• Bearing wear causes shaking

• Noise increases under load

Loose Mountings

Loose bolts or mounts can cause:

• Movement in driveline

• Sudden vibration changes

Transmission Output Issues

Sometimes vibration originates from:

• Gearbox misalignment

• Output shaft wear

Why It Matters

Ignoring vibration can lead to:

• Driveshaft failure

• Transmission damage

• Roadside breakdown
