Parts for your 2017 Subaru Impreza-Wheel hubs

Understanding and Maintaining Wheel Hubs on the 2017 Subaru Impreza

The 2017 Subaru Impreza, like many modern vehicles, relies on a vital component in its wheel assembly called the wheel hub. The wheel hub is an essential part that plays a critical role in connecting the wheels to the car while allowing them to spin freely and securely. If you drive a 2017 Impreza, it's definitely useful to have a basic understanding of what wheel hubs do, why they matter, and when they might need a bit of attention or replacement as part of regular servicing.

So, what exactly is a wheel hub? Basically, it is a metal assembly that sits between the axle and the wheel. It often houses the wheel bearings, which enable smooth rotation of the wheels, and it also includes studs onto which the wheel bolts or nuts are secured. This means the wheel hub is not just a simple connection point but also a crucial element for the safe and efficient operation of the vehicle's wheels.

On the 2017 Subaru Impreza, the wheel hubs are definitely used and designed to meet the performance and safety standards expected from Subaru's engineering. This vehicle uses a front-wheel-drive or all-wheel-drive setup depending on the trim and specifications, and either way, the wheel hubs are key to ensuring the wheels are securely mounted and the bearings function correctly. These hubs support the weight of the vehicle, allow the wheels to rotate smoothly, and maintain proper alignment for handling and tyre wear.

Wheel hubs on the Subaru Impreza also incorporate the wheel speed sensors for the anti-lock braking system (ABS) and traction control. This integration means the hubs are not just mechanical components, but part of the safety system that monitors wheel rotation and helps maintain control under various driving conditions.

When it comes to maintenance or replacement, wheel hubs generally do not require frequent attention under normal driving conditions. However, over time, wear and tear from road conditions, exposure to water, dirt and grime, along with the stresses of everyday driving, may affect their performance. Bearings inside the hub assembly can wear out, leading to noises, vibrations, or even potential safety risks if left unattended.

It's advisable to keep an eye out for common symptoms that could signal a failing wheel hub on your 2017 Subaru Impreza:

• Unusual noises such as grinding or humming coming from the wheel area
• Vibrations felt through the steering wheel or floorboard
• Uneven or accelerated tyre wear
• ABS warning light or traction control warning on the dashboard
• Loose or wobbly wheel when the car is jacked up

If any of these issues arise, it's a good idea to book in a professional inspection. Replacing the wheel hub assembly on an Impreza usually involves removing the wheel, brake components, and sometimes the axle nut, before swapping out the old hub for a new one. Subaru wheel hubs are typically sold as complete assemblies with bearings pre-installed, making replacement more straightforward and ensuring the correct fitment and performance.

Regular servicing of your Subaru Impreza will often include checks on the wheel hubs and bearings, especially if the vehicle has done significant mileage or if you frequently drive on rough or unsealed roads. Greasing and lubricating bearings might be part of some servicing routines on older or high-mileage vehicles, but on newer Imprezas, wheel bearing replacement is usually done by replacing the entire hub assembly because the bearings are sealed and maintenance-free.

Another pointer is to ensure wheel bolts or nuts are tightened to manufacturer torque specifications when reinstalling wheels. Incorrect torque can lead to excessive stress on the wheel hub and premature failure. It also plays a role in maintaining safe and precise wheel alignment and overall handling.

In essence, the wheel hub is a relatively small but highly significant component on the 2017 Subaru Impreza. It ensures that the wheels spin smoothly, remain securely fastened, and provide vital data to electronic safety systems. Paying attention to wheel hub health and ensuring timely replacement when required will support smoother rides and help keep your Subie handling its best for years to come.
