A differential rebuild is the best option when internal wear has progressed beyond a simple repair – or when you want the confidence of a refreshed diff before a long trip, heavy towing, or regular off-road use.
WA Diffs performs differential rebuilds in Perth with a focus on correct setup. Bearings and gears don’t just get swapped; they must be set up to precise tolerances so the diff runs quietly, stays cool and lasts.
If you’ve been driving with a whine for a while, or you’ve found metal in the oil, a rebuild can prevent a sudden failure that strands you or damages other driveline components.
Rebuild scope varies by vehicle, but commonly includes:
If the crown wheel and pinion teeth are pitted, chipped, or severely worn, replacing gears may be recommended. Gear damage is often caused by running low on oil, contamination, or extended driving with noisy bearings.
Where gears are replaced or ratios changed, accurate setup becomes even more critical. Small errors in pinion depth or backlash can create a whine that never goes away.
After a rebuild, we may recommend a run-in period, especially if new gears are fitted. That typically means avoiding heavy towing or sustained high-load driving for the initial bedding-in period, then rechecking oil condition if advised.
We’ll talk you through aftercare based on your vehicle and the parts fitted so you get the best life from the rebuild.
If your diff is noisy, leaking, or you’re planning a demanding trip, call +61 8 9417 9930 to discuss a rebuild. Provide your vehicle make/model and describe when the noise happens (accelerating, decelerating, turning).
