Parts for your 2020 Subaru Legacy-Wheel bearings

2020 Subaru Legacy Wheel Bearings: What They Are and Why They Matter

The 2020 Subaru Legacy, like most modern passenger vehicles, definitely uses wheel bearings as a critical component of its wheel assembly. Wheel bearings are essential parts that allow the wheels to spin smoothly while supporting the weight of the vehicle. Without properly functioning wheel bearings, a car like the Subaru Legacy would experience increased friction, uneven tire wear, and could develop steering or handling issues. So, wheel bearings are very much relevant and fitted to the 2020 Subaru Legacy.

Wheel bearings are small but heavy-duty components that sit between the wheel hub and the axle. Their job is to facilitate the smooth rotation of the wheels by reducing friction between moving parts. For the 2020 Subaru Legacy, these bearings are sealed units which means they come packed with grease and are protected from dirt, water, and road debris by seals. This design helps them last longer and require less routine maintenance compared to older styles of wheel bearings.

While some vehicles once had wheel bearings that needed periodic cleaning and repacking with grease, most modern cars, including the Subaru Legacy, use sealed bearings. This means they are considered "fit and forget," though they are still subject to wear over time. When wheel bearings fail, you might notice a humming or growling noise coming from the wheels, uneven tyre wear, or in extreme cases, wobbling or vibrations while driving.

Although wheel bearings are built to last, wear and tear is inevitable due to the high loads and constant rotation they endure. For a vehicle like the 2020 Subaru Legacy, typical mileage before needing bearing attention can vary, but most bearings can easily last over 100,000 kilometres if the vehicle is not driven in particularly harsh conditions. Regular servicing can help spot the early signs of bearing failure and prevent expensive repairs or dangerous situations.

So, what does routine maintenance or replacement look like for Subaru Legacy wheel bearings? It is not usually a DIY task for most car owners due to the specialised tools and skills required. Replacing wheel bearings involves removing the wheel hub assembly and pressing out the old bearing before installing a new one. This process has to be done precisely to ensure correct fitment and to avoid damaging the new bearing.

That said, staying alert to any warning signs is the best course for owners. These can include:

• Unusual noises like humming, grinding, or growling coming from the wheels while driving
• Increased vibration or wobbling felt in the steering wheel or throughout the vehicle
• Uneven or rapid tyre wear that can indicate excessive play in the wheel assembly
• ABS warning lights or traction control system alerts, which could sometimes be linked to faulty wheel speed sensors integrated with some wheel bearings

If a driver hears or feels any of these signs, a prompt inspection at a trustworthy workshop is a smart move. Mechanics can assess the bearings and other related wheel components, ensuring the Legacy remains safe and smooth on the road.

Many Subaru service centres recommend that while wheel bearings are durable, doing a detailed inspection every 40,000 to 60,000 kilometres as part of regular servicing can help catch any issues early. This is especially true if the vehicle is driven on rough roads, in off-road conditions, or in very wet or dusty environments, as these factors can put extra strain on the bearings.

Choosing quality replacement parts is also crucial if a bearing replacement is needed. Subaru genuine parts or high-quality aftermarket bearings designed specifically for the 2020 Legacy ensure proper fitment and performance. Using sub-par parts may save money upfront but could lead to premature failure and additional repair costs down the track.

In terms of cost, bearing replacement can be a bit pricey due to the labour involved, but remember that maintaining well-functioning wheel bearings plays a vital role in vehicle safety and ride comfort. Well-maintained bearings contribute to better fuel efficiency, as less friction means the engine doesn't have to work as hard to turn the wheels.

To wrap a wheel bearing maintenance story up, it's fair to say that the 2020 Subaru Legacy relies on these integral components more than you might realise. They quietly support the smooth rotation of your wheels and by extension your entire driving experience. Monitoring their condition and taking care of them during servicing can help ensure that your Legacy drives quietly and safely for many years and kilometres ahead.
