Parts for your 2016 Subaru Impreza-Wheel bearings

2016 Subaru Impreza wheel-bearings

Wheel-bearings absolutely are used on the 2016 Subaru Impreza. Subaru’s own Service Manual for 2016MY Impreza (GP/GJ) lists front and rear “hub unit bearings”, and the Subaru Genuine Parts Catalogue shows complete bolt-in hub assemblies for both axles. Major bearing makers (e.g., Timken and NTN) also publish application listings for 2016 Impreza hub-unit wheel-bearings. So this part is 100% relevant to the model.

On this Impreza, the wheel-bearings are a sealed hub unit. Their job is to let the wheels spin smoothly while carrying the vehicle’s weight, keeping rolling resistance low and the steering and ride nice and quiet. The hub usually integrates the bearing, wheel flange and ABS encoder, which is why a crook bearing can sometimes trigger ABS or stability control warnings.

Because they’re sealed, there’s no greasing or adjustment during routine servicing. What matters is regular inspection and a good ear on road tests. Typical tell-tales include a speed-related hum or growl that changes when gently weaving, a faint vibration through the cabin, warmth at the hub after a drive, ABS lights, or slight wheel play when checked at 12 and 6 o’clock with the car safely lifted.

• Recommended checks at service: road test for droning noises, spin and feel for roughness, inspect for play or leaking grease, scan for ABS faults, and look for uneven tyre wear patterns.
• Care tips: avoid kerb strikes and deep potholes, keep tyres correctly inflated and balanced, and always torque wheel nuts evenly to spec.

If replacement’s needed, the 2016 Impreza uses a bolt-on hub unit, so the fix is to swap the assembly on the affected corner. Quality matters here: choose a reputable hub with the correct ABS encoder style. Use new hardware where Subaru specifies (often a one-time-use axle nut), and torque everything to the Service Manual specs. If the knuckle or strut bolts are loosened, get the wheel alignment checked afterwards. A noise on one side doesn’t mean both sides must be changed, but at high kilometres it can be sensible to plan the opposite side if there are early signs of wear.

Many owners see 120,000–200,000 km from factory hubs, but local road conditions and driving style play a big part. Catching a failing bearing early keeps the ride quiet and protects tyres and brake components.

Popular questions

Do 2016 Subaru Impreza wheel-bearings need regular servicing?
They’re sealed hub units, so there’s no periodic greasing or adjustment. During routine services, a mechanic will road test, check for play or roughness, and listen for humming. If noisy or loose, the whole hub assembly is replaced.

How can someone tell which wheel-bearing is failing?
A steady drone that changes when gently swerving is a classic sign. Pinpointing the exact corner is best done with a proper road test and workshop checks (chassis ears, wheel play inspection). Tyre noise can mimic a bearing, so it’s smart to rule that out first.

Is an alignment needed after replacing a wheel-bearings hub?
If the job only involves the bolt-on hub, usually not. If the knuckle-to-strut bolts are loosened or the suspension is disturbed, an alignment check is recommended to keep tyre wear even and handling spot on.
