Differential Repair in Perth

Fix leaks, bearings and setup issues before they become failures

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.

Differential repairs we commonly perform

Depending on diagnosis results, a repair may include:

  • Pinion seal replacement (common cause of oil loss at the tailshaft end)
  • Axle seal replacement (oil at wheels/axle ends, contamination of brakes)
  • Bearing replacement (pinion bearings, carrier bearings) where gears remain serviceable
  • Breather inspection/replacement to reduce seal failures and oil push-out
  • Backlash and preload correction to reduce noise and premature wear

Housing reseal and hardware replacement where required

How to tell if it’s a repair or a rebuild

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.

What you can do before your booking

To help us diagnose faster, note down:

  • When the noise happens (acceleration, deceleration, turning, coasting)
  • Approximate speed range where it’s most noticeable
  • Whether the vehicle has been modified (tyres, lift, gearing, lockers)
  • Any recent trips (water crossings, beach driving, heavy towing)
