Differential Units

A differential unit has three key jobs:

• Transfer power to the wheels so your car moves efficiently
• Provide the final drive gear ratio of your vehicle
• Allow the wheels to turn at different speeds when cornering, which keeps handling smooth and prevents tyre wear

Without a properly functioning diff, your car would struggle to corner safely or deliver power evenly to the wheels.

Your car often gives early warnings when the diff isn’t working properly. Watch out for:
• Whirring noises when decelerating
• Whining noises while accelerating, often noticeable between certain speeds (e.g., 80–90 km/h)
• Rumbling sounds that change when turning
• Clunking or clanging noises at intervals
• Clunking specifically when cornering

If you notice any of these, it’s a good idea to have your differential checked. Catching problems early can save you from bigger, more costly repairs down the line.
