What is a CV shaft?

Signs your CV shaft may need replacement

Watch out for these common symptoms of a failing CV shaft:

• Clicking or popping noises when turning sharply

• Grease splatters on the inside of your wheels or undercarriage (indicative of a torn CV boot)

• Vibrations while accelerating or at higher speeds

• Knocking sounds during acceleration or deceleration

• Binding or hopping feeling when steering

• Vehicle not moving if the shaft is severely damaged

If you notice any of these signs, it’s essential to book an inspection promptly to avoid further damage or safety risks.

How is a CV shaft replacement performed?

Here’s what a typical CV shaft replacement involves:

Preparation - The vehicle is raised and secured safely. The axle nut and wheel lug nuts are loosened.

Wheel Removal - The affected wheel is removed for better access to the CV shaft.

Disconnect Components - The technician may remove nearby components like the brake caliper or suspension parts for easier access.

Remove the Old CV Shaft - Using specialised tools, the damaged CV shaft is gently dislodged from the transmission or differential.

Install the New CV Shaft - The new shaft is carefully inserted and aligned with both the transmission and wheel hub.

Reassemble Components - All removed parts are refitted, and fasteners are torqued to the manufacturer’s specifications.

Testing - A road test confirms that the new CV shaft is functioning properly and that the symptoms have been resolved.

Repair vs replacement: What’s best?

While some CV joints or boots can be repaired individually, complete shaft replacement is often the more practical solution in these cases:

Extensive Wear or Damage
Severe wear to the joint components or shaft usually warrants full replacement.

Contaminated CV Boot
If the protective boot is torn and dirt or moisture has entered, replacing the whole shaft ensures reliability.

Cost-Effectiveness
In many instances, replacing the CV shaft costs less than extensive labour to repair individual parts.
