What are Differential Lockers?

Your vehicle’s diff locks are sophisticated parts of your traction control system. A differential locker, or locking differential, is a device that allows the wheels to rotate at the same speed, regardless of the load on each wheel, by locking the two axles together. This mechanism is crucial, particularly on slippery surfaces or in off-roading situations where traction is compromised.

The Importance of a Traction Control System

Traction control is vital for off-road vehicles while traversing rough terrain. Without this system, if one wheel is airborne while the other navigates an obstacle, the vehicle might lose power due to wheel slippage, preventing progress over the terrain. Traction control systems are also beneficial in rear-wheel-drive cars, enhancing grip and stability in various driving conditions, such as rainy weather or on icy roads.

Servicing your Locking Differentials at Auto Trans R Us

Differential lockers, particularly air lockers which utilise compressed air to engage the lock, can undergo significant wear and tear, especially when frequently exposed to harsh conditions. Regular servicing of your locking differential, including checking the side gears, differential action, and overall function, can prevent common issues like wheel slippage and ensure reliable performance.

Frequently Asked Questions

What Are Some Common Traction Control Issues?

There can be a few different issues with traction control systems. One is that they can sometimes be too sensitive, and they end up slowing down the car even when there's no need. This can cause problems on surfaces covered in snow or ice as it makes it harder for the driver to maintain control of the car.

In some modern traction control systems with an automatic diff locking safety feature, the system's sensors, wiring, or computer can be slow to respond or faulty, causing a wheel slip when an airborne excessively spinning wheel lands.

If you notice any issues with your diff lock or your traction control light is on, it is best to have it looked at by a professional as soon as possible.

When Should You Use Your Differential Lock?

To avoid wheel spin or losing traction, it's best to know all the right situations to engage your differential lock. Some of the best times to use your diff lock include:

While climbing over terrain with large obstacles: Without a diff lock in this situation, your vehicle will lose traction if the electronic traction control system registers a spinning wheel.

While off-road driving on a straight path in first or second gear: This will create a smoother drive as the wheel speed isn't impacted each time one wheel is lifted off the ground, it will also help give your car more power.

When Should You Disable Your Locking Differential?

It can be very difficult to steer your vehicle while differential lockers are engaged at the wrong time. The best times to ensure your diff locks are disabled include:

When making a turn: With diff lockers engaged, you will require a very large turning circle.

When all wheels are on the ground with weight equally distributed across the front and rear axles: There is no need for extra power or traction control in this situation.

What Role Does a Locking Differential Play in Off-Roading?

A locking differential ensures that both wheels on an axle turn at the same speed, providing maximum traction in off-road conditions where one wheel may lose contact with the ground.

Can a Diff Lock Be Used on Standard Roads?

Using a diff lock on standard roads is not recommended as it can lead to difficult handling and increased wear on the vehicle, especially when cornering.

How Does a Traction Control System Interact with a Differential Lock?

The traction control system manages wheel spin by automatically adjusting power output, while a differential lock manually ensures both wheels on an axle rotate at the same speed, enhancing traction in low-grip situations.

Are Air Lockers Better than Traditional Locking Differentials?

Air lockers offer quicker and more versatile engagement compared to traditional mechanical lockers, making them ideal for drivers who need to switch between locked and open differentials frequently.

How Do I Know If My Differential Locker Needs Servicing?

Signs that your differential locker may need servicing include unusual noises from the drivetrain, difficulty in turning, or noticeable changes in vehicle handling.
