Keep your wheels in motion with our diff repairs

Read customer reviews

Ever wondered how your car’s wheels start turning when your foot hits the accelerator? The diff also known as a ‘Final Drive Assembly’, is major driveline component that provides the final overall ratio reduction between engine output speed and vehicle speed. Without it, your car would barely do more than 30 KPH! This is why it’s so integral to vehicle operation. It’s internal gears also allow the rear wheels to spin at different speeds so you can take corners smoothly.

While the diff is one of the most reliable car components, it’s not immune to issues that could leave you stranded on the side of the road without a working ride. So if your ride’s not as smooth as it used to be, you could be in need of a diff service.

How we keep your diff humming

Differential repairs can involve anything from topping up the fluid through to fully removing the diff centre itself from your vehicle for a thorough inspection. For more complex repairs, your mycar mechanic will remove the diff, take it apart to check that each piece is working before fixing or replacing the faulty parts and putting it back together. Depending on the extent of the repair and the type of diff, a repair can take anywhere from a few hours to up to a week.

If it turns out that your diff can’t be saved, you could be up for a complete rear differential replacement instead.

How much does a rear differential replacement cost?

You can expect your car differential repair cost to set you back around $400-$600 or $1500-$3000 for a rear differential replacement. This final cost depends on the make and model of your car as well as the type of differential.

At mycar, we understand how important your car is to you, which is why we do our best to provide everyone with access to quick and affordable repairs. To take the stress out of an unexpected car repair bill, we’ve teamed up with Zip Pay so you can pay for your repairs in regular, more manageable instalments.

FAQ

Can I drive with a broken diff?

You should avoid driving with a broken diff or risk making it worse. If you notice your car’s making strange noises, giving off odd smells or has a dragging, binding feeling as you’re driving, it’s usually a good indication that your car’s in need of a check over to see what’s going on. In the most extreme cases of differential failure, your car won’t move due to broken axles or gears, so you literally won’t be able to drive even if you wanted to.

Is it worth fixing the rear differential?

This all depends on the car itself and the extent of the damage. If you’re in for a basic repair that’ll set you back a few hundred dollars then it’s usually worth fixing the rear diff. If you’re looking at a diff replacement that could cost you thousands of dollars, then the price of replacing the part could end up costing you more than what the car’s actually worth.

What does a bad diff sound like?

There’s a few different noises that usually indicate a bad diff. These noises will often become louder or move to a higher pitch as you accelerate. Whining, humming, grinding and clunking noises are all common signs of a bad diff. If you notice any of these sounds coming from your car, give your local mycar a buzz and chat to one of our friendly team members about your concerns.
