Everything You Need to Know About Wheel Bearings on the 2018 Subaru Forester

The 2018 Subaru Forester is a reliable and practical SUV, known for its all-wheel drive capabilities and solid engineering. When it comes to the wheel assembly, this vehicle is fitted with wheel bearings, just like most modern vehicles. Wheel bearings play an essential role in the overall function and safety of the Forester, so knowing what they do and how to maintain them is important for any owner.

Wheel bearings are small, but critical components located within the wheel hub. They allow the wheel to spin freely with minimal friction while supporting the vehicle's weight. The bearings consist of steel balls or rollers enclosed in a metal ring called a race, designed to facilitate smooth movement. The 2018 Subaru Forester uses sealed wheel bearing units, meaning they come pre-lubricated and sealed from the factory to keep dirt and moisture out. This design reduces maintenance needs, but it does not make the bearings wear out any less over time.

The purpose of wheel bearings in the Forester is to enable smooth and efficient rotation of the wheels while bearing the load of the vehicle. They also help to maintain stable wheel alignment, which contributes to better handling and improved tyre wear. Without properly functioning wheel bearings, the wheels would grind and wobble, leading to poor driving performance and potential safety hazards.

Since the 2018 Forester has all-wheel drive, wheel bearings are located on all four wheels. This means that each wheel hub has a set of bearings that supports the wheel and allows it to spin freely. The AWD system depends on smooth and consistent wheel rotation to provide maximum traction across different terrains and driving conditions. Faulty or worn wheel bearings can negatively impact this system, causing noise, vibrations, or uneven tyre wear, and may even affect the vehicle's handling.

Wheel bearing wear and failure is a gradual process that typically happens over many kilometres. Owners might notice a few warning signs indicating wheel bearing issues. Common symptoms include a humming or growling noise coming from the wheels, especially when cornering or accelerating, excess play or wobble in the wheel itself, or uneven tyre wear. Catching these signs early on can prevent more serious damage to the vehicle's suspension or wheel hub assembly.

When it comes to replacing or servicing wheel bearings on the 2018 Subaru Forester, it is often recommended to have the bearings inspected during routine servicing, especially after 100,000 kilometres or if any symptoms are present. Since these bearings are sealed units, they cannot be re-greased or repaired and must be replaced as a whole unit if worn or damaged. Subaru typically advises replacing wheel bearings in pairs on the same axle to avoid uneven wear and driving issues.

Replacing wheel bearings involves removing the wheel, brake components, and hub assembly to access the bearing. It is a precise job that requires special tools and expertise to avoid damaging the new bearings or associated parts. For this reason, many Forester owners prefer having replacement or diagnosis carried out by a trusted mechanic or dealership, though a knowledgeable DIY enthusiast could undertake the task with the right equipment.

Regular checks and prompt attention to any unusual noises or sensations can prolong the life of wheel bearings. Avoiding rough off-road driving or potholes at high speeds also helps reduce stress on the bearings. On top of this, keeping tyres balanced and aligned ensures the wheels and bearings work smoothly together for longer.

Maintaining the wheel bearings on a 2018 Subaru Forester is a small investment for peace of mind and vehicle safety. While these components may seem minor, they are fundamental to ensuring the wheels rotate effortlessly and safely. If a Forester owner hears any strange noises, feels vibrations, or notices uneven tyre wear, checking the wheel bearings should be high on the list of potential culprits.

In the end, wheel bearings may be out of sight, but they should never be out of mind for anyone wanting to keep their Forester running smoothly. Proper care and timely replacements can keep these essential parts doing their job silently and efficiently, mile after mile.
