Differentials aren’t something most drivers think about – until they start making noise. This FAQ hub answers the most common questions we hear in the workshop about diff whines, clunks, leaks and maintenance intervals.
If you’re in Perth and you’re unsure whether the noise you’re hearing is a diff, a wheel bearing or another driveline component, WA Diffs can help you diagnose it properly and recommend the right fix.
For urgent advice or to book an inspection, call +61 8 9417 9930.

Start here:

Many noises that sound like a differential can come from other areas: wheel bearings, tyres, CV joints, tailshaft joints or even transmission components. Getting the right diagnosis first can save you a lot of time and money.
If you’d like us to check it, see our Differential Inspection & Noise Diagnosis page, or call +61 8 9417 9930 to book.

If you’re preparing for a long-distance drive, towing, or a remote trip, consider a preventative differential service. Fresh oil and a quick leak check is cheap insurance compared to a breakdown in the middle of nowhere.
WA Diffs can recommend a maintenance plan based on your vehicle and usage.

If you’re due for maintenance, hearing a light whine, or noticing a damp housing, book a differential service with WA Diffs. Call +61 8 9417 9930 and let us know your vehicle make/model and whether it’s a front diff, rear diff or both.
