Home › Vehicles › Audi › Audi A5
The short version
- The A5 wheel bearing story is the B8 platform’s: the same BR930817K front kit family the A4 and Q5 use.
- Kits come with single-use stretch bolts; the rear follows its own VIN-matched kit.
- The S5 and the Sportback share the chart with the plain coupe.
- Quattro is standard equipment here and does not change the listings.
Audi built the A5 as an A4 in a sharper suit, and the wheel ends came along unchanged. If you have read this site’s Q5 page, you already know this car’s whole bearing culture.
One kit family across the B8 range
The front A5 wheel bearing arrives as the BR930817K kit or its Audi equivalent, a sealed unit with fresh bolts, bolted into the carrier.
A4 sedans, A5 coupes, Q5 crossovers: one platform, one front kit family, 2008 through 2017.

The bolts rule, again
These kits include fresh torque-to-yield bolts because the old ones must not go back in.
The full explanation lives on the Q5 page and the single-use parts page.
The S5 changes driving, not parts
The V8 and supercharged S5s ride on the same bearing kits as the four-cylinder coupe; what changes is how hard those bearings corner. On a driven-hard car, a hum that answers load through sweepers deserves same-week attention, per the noise when turning page.
The sedan sibling is on the A4 page, and the make overview on the Audi page.
Diagnosing an A5 wheel bearing
- Confirm B8 or B9 generation first.
- Rule out wide performance rubber, the eternal imitator.
- Weave at speed and place the hum.
- Buy the kit, front or rear, and use its bolts.
- Cross-shop A4 and Q5 listings; same family.
The routine is on the checking page and the tire noise page.
Common questions
Which A5 wheel bearing do I buy?
For a B8 front, the BR930817K kit family or Audi’s OEM equivalent. Rears go by VIN.
Does the S5 differ?
No. Same kits, more cornering load.
Do A4 and Q5 parts fit?
The front kit family is shared across the B8 platform. Match years and confirm.
Do I need a press?
No traditional press; the kit bolts into the carrier. The corner still comes properly apart.
Can I reuse the bolts?
Never. They stretch by design and are included fresh in every kit.
