Diff servicing, repairs, rebuilds and
upgrades for Perth vehicles

If your diff is whining, clunking, leaking oil or vibrating under load, it’s a sign something inside the differential isn’t happy. Left unchecked, small issues like worn bearings or low oil can turn into costly gear damage.

WA Diffs is a Perth-based differential specialist workshop focused on diff repairs, rebuilds, replacements and performance upgrades for 4WDs, utes and passenger vehicles. We take a methodical approach: diagnose the cause, explain the options, then carry out the correct setup so your vehicle drives quietly and reliably again.

For a quote or to book an inspection, call WA Diffs on +61 8 9417 9930 or send your vehicle details via the contact form.

Differential services we offer

Choose a service based on your symptoms, your usage (daily driving, towing, off-road) and your budget:

Differential servicing and oil changes (front, rear and 4WD/AWD)
Noise, vibration and leak diagnosis (whine, clunk, humming and driveline vibration)
Differential repairs (seals, bearings, shim adjustments and related hardware)
Differential rebuilds (bearing kits, gear inspection, correct preload/backlash setup)
Differential replacements (reconditioned centres, new assemblies, swap-over options)
LSD upgrades and diff locker installations (traction upgrades for work and off-road)
Gear ratio changes (to suit larger tyres, towing loads or better drivability)

Common signs your diff needs attention

A differential problem doesn’t always feel dramatic at first. Common early warning signs include:

Whining or howling that changes with speed or throttle (often bearings or gear pattern issues)
Clunking on take-off, gear changes or when shifting between drive/reverse
Vibration under acceleration, towing or at highway speeds
Oil leaks around pinion seals, axle seals or the diff cover
A burning smell or very dark oil after heavy driving
Metal flakes on a magnetic drain plug or in the oil during a service

I had noises and concerns about my front diff. They test drived it, inspected it and made a good plan to monitor over the next few months. Same day I called up and all for free. Happy I went in.
