Home › Vehicles › Audi › Audi A7 Wheel Bearing Part Numbers
The short version
- The Audi A7 wheel bearing does not appear anywhere in the catalogs under its own name. They list other Audis well past the A7’s 2012 launch, yet never added an A7 row.
- The C7 A7 shares its platform with the C7 Audi A6. The A6 family lists a rear bearing, 512557, with a 32mm inside diameter for 2009-2015 rows.
- That number is a platform-sharing candidate only. Confirm the bearing inside diameter and the VIN before ordering it for an A7.
- No front number is documented at all for the A7 or the shared A6 platform rows given here, so match the old part or the VIN.
Audi launched the A7 in 2012, and the aftermarket catalogs never gave it a listing of its own. No row anywhere carries the A7 name directly. The car rides on the same C7 platform as the Audi A6 of the same era, and that is the only reason a candidate number exists at all.
Audi A7 wheel bearing quick reference
The Audi A7 wheel bearing question has to be answered through the shared C7 platform. The catalogs never listed the A7 on its own.
512557 is worth checking, but only after confirming the bearing’s inside diameter and cross-checking the VIN.

Lookups run through the cross reference page.
Candidate, not a confirmed fit: 512557 comes from the A6 C7 family’s rear listings, not from an A7-specific row. The catalogs identify it by a 32mm bearing inside diameter, not by model name. Confirm that diameter against the old part, or confirm by VIN, before ordering it for an A7.
The front Audi A7 wheel bearing has no documented number at all in these catalogs. Match the old part or the VIN there as well.
A shared C7 platform, not a shared listing
The C7 A7 and the C7 A6 share their underpinnings closely. Audi built them on the same production lines for years. That closeness is exactly why the A6’s rear bearing rows are a reasonable place to start.
The smaller A5 shares less of the A7’s structure. Its numbers are not a useful cross-check here.
Confirming a candidate part before it goes on the car
A bearing inside diameter is a hard measurement, not a judgment call. It is worth checking against the old part before trusting a platform-sharing candidate like 512557. The VIN decode through Audi’s model lineup is the other half of that confirmation.
Skipping that check on a car the catalogs never labeled directly is how the wrong bearing ends up on an A7.
Diagnosing an Audi A7 wheel bearing
- Listen for a road-speed hum. A worn wheel bearing drones louder as speed climbs, not with the exhaust note.
- Weight-shift on an empty road. A gentle sweep side to side loads each bearing in turn. The sound typically grows on the bad side.
- Rock the wheel off the ground. Grip the tire at opposite points and check for play. On a quattro A7, rule out a loose driveshaft or CV joint first.
- Check for ABS or quattro warnings. The wheel speed sensor lives inside the hub bearing. A failing bearing can trigger a stability or all-wheel-drive warning light.
- Confirm through a turn. Cornering loads a bearing unevenly. A noise that shifts pitch through a curve backs up the diagnosis.
Common questions
What is the Audi A7 wheel bearing part number?
The catalogs do not list one under the A7 name. The closest reference is 512557, a rear bearing from the shared A6 C7 platform identified by a 32mm inside diameter, and it needs confirmation before use.
Why is there no A7-specific wheel bearing listing?
The catalogs cover other Audis of the same years but never added the A7 under its own name. Its lookups have always run through the shared A6 platform instead.
Can an A6 rear bearing be used on an A7?
It is a reasonable candidate given the shared C7 platform. Confirm the bearing inside diameter and the VIN before ordering it rather than assuming it fits.
What about the front Audi A7 wheel bearing?
There is no documented number for it in these catalogs at all. Match the old part or confirm the correct hub by VIN.
Does the A5 share bearings with the A7?
Not usefully. The A5 shares less structure with the A7 than the A6 does, so its numbers are not a good cross-check here.
