Parts for your 2016 Subaru Impreza-Wheel bearings

2016 Subaru Impreza wheel bearings: what they do and when to replace them

Wheel bearings are absolutely fitted to the 2016 Subaru Impreza (GJ/GP). Subaru’s Factory Service Manual (via Subaru Technical Information System) lists bolt-on hub unit bearings front and rear in the Front Axle and Rear Axle sections, and the Subaru parts catalogue shows complete hub-and-bearing assemblies per corner. Independent repair manuals for 2012–2016 Impreza models back this up as well. So yes—wheel bearings are relevant to every 2016 Impreza variant sold in Australia and New Zealand.

On a 2016 Subaru Impreza, the wheel bearings are sealed hub units that let the wheels spin freely while carrying the car’s weight and cornering loads. They also keep everything precisely aligned so the tyres wear evenly, the ABS reads wheel speed accurately, and the drive stays quiet. Being sealed means there’s no greasing or adjustment, once a bearing wears out, the fix is to replace the whole hub assembly.

There’s no set replacement interval in the factory schedule. Instead, technicians check them at routine services. The workshop will spin the wheel, feel for roughness, and check for play with the wheel off the ground. Common tell-tales include a humming or droning that rises with speed, a change in noise when turning, light vibration through the cabin, uneven tyre wear, or an ABS light if the tone ring signal goes wonky. In coastal Aussie and Kiwi conditions, corrosion can hasten wear, so keeping the hub area clean and avoiding direct pressure-washer blasts at the seals helps.

When it’s time to replace one, quality matters—OE or reputable aftermarket hub units last longer and stay quieter. The job involves removing the brake assembly, unbolting the hub from the knuckle, and torquing the axle nut and mounting bolts to factory spec. Correct torque is critical on Subarus, over- or under-tightening can shorten bearing life. An alignment usually isn’t required if only the hub is changed, but it’s smart to have the steering and tyres checked afterwards, especially if the car’s been driven a while with a noisy bearing. If one side fails, the opposite side isn’t automatically due, yet it’s sensible to inspect it closely the same day. With proper fitment and good tyres, many Impreza bearings run past 150,000–200,000 kilometres on local roads.

• Watch for: humming with speed, play at 12-and-6 o’clock, ABS warning, heat at the hub after a short drive.
• Good habits: torque fasteners to spec, keep wheel faces clean, rotate tyres, and address suspension knocks early.

Popular questions about 2016subaruimpreza wheelbearings

How long do wheel bearings last on a 2016 Subaru Impreza?

Many owners see 150,000–200,000 kilometres or more, but life varies with road quality, tyre setup, and exposure to water or road salt. There’s no fixed interval—replace when noise, play, or roughness is present.

Is it safe to drive with a noisy wheel bearing?

It’s risky. A failing bearing can overheat, affect ABS readings, and in extreme cases lead to hub damage. It’s best to book an inspection promptly to avoid bigger repairs and keep the car safe.

Do you need a wheel alignment after replacing a hub bearing?

Usually not, because the hub bolts to the knuckle in a fixed position. Still, many workshops recommend a quick alignment check to confirm steering is straight and tyre wear stays even.
