Parts for your 2017 Audi Q5-Wheel hubs

2017 Audi Q5 wheel hubs — what they do and when to replace them

Yes, the 2017 Audi Q5 is fitted with wheel hubs. Factory technical sources such as Audi’s erWin workshop manuals and the ETKA parts catalogue list unitised hub-and-bearing assemblies at each corner of the Q5 (with integrated ABS encoder), and major bearing manufacturers like FAG/Schaeffler and SKF catalogue direct-fit hub units for this model. So wheel hubs are absolutely relevant to servicing and repair on a 2017 Q5.

On the 2017 Q5, each wheel hub is the solid mounting point that the wheel bolts to, supporting vehicle weight while allowing the wheel to spin smoothly. The hub carries the brake disc, mates to the driveshaft splines on quattro variants, and houses the encoder ring for the ABS/ESC wheel speed sensor. Audi uses sealed, unitised hub-and-bearing assemblies on this model, meaning there’s no periodic greasing, when a hub wears out, the complete unit is replaced.

As part of routine servicing, a quick hub check goes a long way. With the vehicle safely lifted, they’ll spin each wheel and listen for a rough, growly note, then rock it at the 12 and 6 o’clock positions to feel for play. They’ll also look for uneven tyre wear, brake pad knock-back, or ABS warnings that can point to a failing hub or encoder.

• Telltale signs the Q5’s hub is on the way out:
  • Low, cyclical rumble that rises with road speed (often louder on gentle turns)
  • Free play or notchiness when the wheel is rotated by hand
  • ABS/ESC faults from a damaged encoder or sensor air gap
  • Heat discolouration around the hub or unusual brake pulsation

When replacement’s due, it’s typically a bolt-on job: the unit is fastened to the knuckle from the rear and secured with a single-use axle bolt or nut on driven hubs. Correct torque-and-angle on that fastener is critical, so they’ll follow the factory spec and always use new hardware. Wheel bolts are torqued evenly in a star pattern after refit. If the knuckle or control-arm bolts are loosened during the job, a wheel alignment check is smart practice.

There’s no set lifespan, but many Q5 hubs will run well past 100,000 km. Harsh roads, big potholes, wheel impacts, oversized wheels, and water ingress shorten their life. For longevity, they’ll keep tyres correctly inflated, avoid kerb strikes, rotate tyres on schedule, and wash road salt or beach sand off the brakes and hubs.

Quality matters here: OEM or reputable brands keep noise down and sensor signals clean. Usually only the noisy side needs doing, but on high‑kilometre vehicles they may advise pairing on the same axle to keep things balanced.

Popular questions

Does the 2017 Audi Q5 use a separate bearing or a hub-and-bearing unit?
It uses a sealed, unitised hub-and-bearing assembly. Rather than pressing in a loose bearing, the complete hub unit bolts to the steering knuckle or rear carrier. This design improves stiffness, accuracy for ABS readings, and service speed.

How long do wheel hubs typically last on a Q5?
Many last 100,000–200,000 km, but life varies with road conditions, driving style, wheel/tyre size, and impacts. Regular checks during services help catch wear early before it affects tyres, brakes, or ABS performance.

Can a noisy hub be “re-greased,” or does it need replacing?
They’re sealed units, so once they start rumbling or show play, the fix is replacement. Re-greasing isn’t possible and driving on a failing hub risks ABS faults, increased stopping distances, and uneven tyre wear.
