A whining noise at 80 km/h, a clunk on take-off, or a vibration under load doesn’t always mean the diff is “gone” – but it does mean something needs attention. The key is finding the true source before spending money on the wrong fix.
WA Diffs offers differential inspection and noise diagnosis in Perth to pinpoint whether the issue is in the front diff, rear diff, centre, tailshaft, wheel bearings or related driveline components. Once we identify the cause, we’ll explain the repair options and the likely outcomes in plain language.

Noise and vibration symptoms can be subtle. We often help customers dealing with:
Leaks or low oil that may be causing overheating and wear

A good diagnosis combines test results with your description of when the problem happens. Typical steps include:
Identify whether the noise is from the diff, wheel bearings, tyres, CVs or tailshaft components

Replacing a complete diff assembly without confirming the cause can be expensive and may not fix the problem. For example, a wheel bearing hum can be mistaken for a diff whine, and a tailshaft vibration can feel like an internal diff issue.
By diagnosing first, you can choose the right repair – from a simple seal fix or service, through to a bearing replacement, rebuild or upgrade.

If your diff noise is getting worse, don’t wait for it to fail completely. Call +61 8 9417 9930 and tell us what you’re hearing and when it happens. The more detail you can share, the faster we can narrow it down.
If you’re already certain the issue is internal, see our Differential Repair and Differential Rebuild pages for the next step.
