Differential Repairs Thornbury

Differential Repairs in Thornbury, VIC

Your vehicle's differential (sometimes referred to as a 'diff') is an important component. As well as making a big difference to how your vehicle handles - it can also have a big impact on the wear of other components if you have a diff problem.

As such, it's useful to have some information about how a differential works - and how to tell if something's not quite right.

Don't worry if you explore this guide and decide that you might need differential repairs - we'll explain how Auto Hero can help you to make sure you get the best possible deal from repairs shops in Thornbury, VIC.

How much do differential repairs cost?

It's very difficult to say how much it will cost if you're having differential problems - simply because there's a huge difference in price between repairs and a full replacement.

Adjusting a diff and replacing differential fluid is usually a fairly light job and will often cost somewhere between $300-$750. 

The work is generally easier to carry out on front-engine, rear wheel drive (RWD) vehicles. There's often more work in accessing the diff on front-engine, front wheel drive vehicles - so this might add to labour costs.

Replacing a differential is a significantly longer and more expensive cost - not least because even reconditioned differentials can be expensive. It's not uncommon for a job like this to cost between $1,500 and $3,000.

Don't panic if you think you might need a new differential though - Auto Hero will connect you with the best differential repairs specialist in Thornbury, VIC - so you can find the one that provides an excellent price and quality service.

What is a differential and what does it do?

In simple terms, the differential is the part of the car's drive system (along with the transmission and the tail shaft) that sends transmits power from the engine to the wheels. Take a look under your vehicle and the diff is the bulbous looking part in the centre of your axle.

When it comes to how your car handles, it's not as simple as just turning each wheel the same amount. When you corner, the outside wheel is going a little further than the inside wheel - so there needs to be a difference in speed.

This is where the diff comes in. The internal gears make sure exactly the wheels turn at the correct speed. If they turned at the same speed, one would drag, causing a loss of traction.

What do diff lockers do?

You may hear people talking about 'diff-locks', 'diff lockers' or 'lockable differentials' - especially if your vehicle is a 4x4. Diff lockers are sometimes manual and sometimes automatic.

When you seriously drive a 4x4, a standard differential presents a problem. Ordinarily, it's easy for a diff to know which wheel needs the most drive power because it's the one that's the easiest to turn. However, a wheel being easy to turn when you're off-road doesn't necessarily mean it's on the outside as you corner - in fact, it's more likely to mean that it's on mud or even in the air. As such, it definitely doesn't need more power.

A diff lock does away with this problem by - you've guessed it - locking the differential. When locked, the differential doesn't deliver different speeds - it drives both wheels the same amount, helping you get out of difficult terrain.

What are some signs that you need a diff repair?

Although diagnosing the exact problem with a differential can be a tricky job - you don't have to be a diff expert to notice a few warning signs.

These are the issues to look out for if you think you might be having differential problems:

Whining noises in diif 

The most common symptom that people report when they have diff problems is that their vehicle makes a whining sound. This could be an indication that the diff gears aren't properly lubricated.

Uneven tyre wear

 If your tyres are wearing quicker than expected - or unevenly - it could be a sign that your differential isn't working as it should. This is down to the fact that one wheel may be forced to speed up or possibly drag when you're cornering.

Poor handling

By moving your wheels as different speeds, your diff helps to make sure your car's handling is smooth and predictable. If you're having issues with your diff, your handling might feel slightly 'off' - especially when cornering.

Vibrations in Diff

Your differential is a significant part of the 'drive chain' that takes engine power and delivers it to the wheels. If differential joints begin to wear, you may notice some vibrating through the driveshaft - especially when you accelerate.

Grinding noises

The differential houses a series of interlocking gears - and these can start to grind, especially as the differential gets older. This grinding noise can often increase in volume as you accelerate. 

This almost always indicates that differential repairs are needed - but, caught early, it could just mean a fluid change. However, if this kind of problem is left for too long, it might lead to further damage and a bigger bill.

What do differential systems repairs involve?

As a complex part of your vehicle, there are lots of different issues that can crop up with a differential - but don't panic, many of them are just minor issues that require fairly light repairs.

For instance, the differential gasket that seals the access cover to the diff can degrade over time. If this causes a leak, you may start to get symptoms that could at first sound significant - but are remedied with a new gasket and a fluid top-up. The same is true of other seals through the diff system.

Of course, there are more significant things that can go wrong. Bearings can sometimes fail and gears may need replacing - with spare parts often quite costly. 

More often than not, minor repairs don't involve removing or dropping the differential completely. However, if your diff needs replacing or serious internal work - a mechanic may need to remove it from the vehicle completely.
