Differential Replacement in Perth

Swap-over and replacement options to get you back on the road

When a differential has severe gear damage, long-term noise, or widespread internal wear, replacement can be the most practical and cost-effective solution. A quality replacement also reduces the risk of repeat issues caused by reusing worn components.

WA Diffs provides differential replacement services in Perth, including supply and fit options where available. We can discuss replacement assemblies, swap-over centres and other options depending on your vehicle and the condition of the existing diff.

Call +61 8 9417 9930 to check availability and pricing for your make/model.

Replacement vs rebuild

A rebuild restores your existing diff by replacing worn bearings and, if needed, gears. Replacement swaps the unit for another assembly or centre. Replacement is often recommended when gears are damaged, when the housing is compromised, or when downtime needs to be minimised.

In some cases, a rebuild is still the better option, especially if parts availability is limited. We’ll outline pros and cons before you commit.

What’s included in a replacement job

A professional replacement should include more than physically swapping parts. Depending on the vehicle, we typically cover:

  • Removal of the existing differential/centre (front or rear as applicable)
  • Installation of the replacement unit with correct torque procedures
  • Fresh oil fill to correct specification (including LSD oils where required)
  • Leak checks, breather checks and verification of driveline operation
  • Road testing (where appropriate) to confirm noise and vibration outcomes

Things to consider

Replacement units vary. A used diff might be cheaper upfront, but it can carry unknown wear. A reconditioned or new option often provides the best long-term value when you factor in labour and downtime.

If you’re upgrading tyres, towing capacity or off-road capability, replacement can be a good time to consider an LSD, locker or ratio change.
