Not every differential problem requires a full rebuild or a complete replacement. In many cases, a targeted differential repair can restore quiet operation and reliability – especially when issues are caught early.
WA Diffs provides differential repair services in Perth for front and rear diffs, including leak repairs, bearing replacements and setup corrections. If you’ve noticed a small oil leak or a new noise that’s gradually getting worse, it’s worth inspecting now before internal damage spreads.
Call +61 8 9417 9930 to discuss what you’re experiencing and we’ll recommend the next step.

Depending on diagnosis results, a repair may include:
Housing reseal and hardware replacement where required

A repair is often suitable when the noise is mild, the oil isn’t heavily contaminated with metal, and gear tooth patterns aren’t severely worn. If the diff has been noisy for a long time, has run low on oil, or shows heavy metal debris, a rebuild (or replacement) may be the safer option.
The goal is to choose the right level of work for the condition of the diff, not to over- or under-fix it.

To help us diagnose faster, note down:

If you suspect a leak, bearing noise or driveline issue, don’t wait for it to become a breakdown. Call +61 8 9417 9930 to book a differential repair assessment.
