Parts for your 2019 Subaru Outback-Wheel bearings

Understanding Wheel Bearings on the 2019 Subaru Outback

For anyone driving a 2019 Subaru Outback, knowing about wheel bearings is pretty important. Wheel bearings may not be the most exciting part of a car, but they play a vital role in the smooth running of the vehicle, especially for a versatile SUV like the Outback.

So what exactly are wheel bearings, and why are they used on the 2019 Subaru Outback? Simply put, wheel bearings are components that let the wheels spin with minimal friction. They're usually made up of steel balls held together by a metal ring called a race. These bearings sit inside the hub assembly, which is the central part of the wheel that connects to the axle.

On the 2019 Subaru Outback, wheel bearings are definitely fitted and essential. They are crucial to how the wheels rotate, supporting the vehicle's weight and helping to make sure the ride is smooth and stable. Without properly functioning wheel bearings, the wheels would grind against the hub, resulting in noise, heat, and eventually, severe damage or even wheel failure.

What's good to know is that Subaru, including in the 2019 Outback, uses sealed wheel bearing assemblies. This design means the bearings come pre-lubricated with grease and are sealed off from dirt, water, and debris, which helps them last longer. It also means that instead of needing ongoing greasing or maintenance by the vehicle owner, the whole bearing assembly is usually replaced as a unit when it wears out. This setup makes servicing a bit simpler but still important to keep an eye on.

When should someone think about replacing the wheel bearings on their Outback? There are a few telltale signs to watch out for. A common one is a humming or growling noise coming from the wheels that changes with the speed of the vehicle. You might also notice some vibration or wobbling when driving or feel a looseness in the steering. If these symptoms are left ignored, it can cause uneven tyre wear or worse, impact the vehicle's safety.

Because the wheel bearings deal with such heavy loads and constant motion, over time they do wear out. Factors like driving on rough roads, exposure to water, or high mileage can speed up bearing wear. For Outback drivers who often take their vehicle off-road or on long journeys, it's especially important to stay on top of bearing health.

Maintenance advice for the wheel bearings on a 2019 Subaru Outback mainly revolves around regular inspection and timely replacement. Mechanics will usually check the bearings when the vehicle is lifted on a hoist. They'll look and listen for any play or noise and inspect the bearing seals for leaks or damage. Because the Outback uses sealed bearings, if there's any issue, the best fix is to replace the entire hub assembly rather than try to repair individual bearing components.

One handy tip for Outback owners is to keep an ear out for unusual noises during routine drives and book in a service sooner rather than later if anything sounds off. Also, when new tyres or brakes are fitted, it's a good idea to get the wheel bearings checked to maximise safety and performance.

When replacing wheel bearings, using genuine Subaru parts or high-quality aftermarket components is important. Poor quality bearings can fail prematurely, which might lead to costly repairs down the track. The installation process is precise work done by professional mechanics, as it involves pressing the bearing assembly in and out of the hub and sometimes removing the brake components, making sure everything is torqued to manufacturer specifications.

In terms of service intervals, there isn't a strict replacement schedule for the bearings themselves because they tend to last a long time under normal driving conditions. However, they should be inspected regularly as part of the brake and suspension checks, typically done every 15,000 to 30,000 kilometres or whenever the vehicle is serviced.
