The short version
- A 2013 Audi S4 wheel bearing is 513301 or 512574, and the same two numbers serve front and rear.
- The split comes from inner ring length, 15mm or 19mm, measured on the old part.
- The rear listing runs through 2015, one year short of the front, which continues into 2016.
- On a 2016 car, the front is documented but the rear is not.
Audi built this S4 as the B8 chassis from 2010 through 2016. A 2013 Audi S4 wheel bearing sits right in the middle of that run. The same two part numbers cover either position.

This page covers the 2010-2016 Audi S4: 2010, 2011, 2012, 2013, 2014, 2015, 2016. Other years live on the main Audi S4 wheel bearing page.
A 2013 Audi S4 wheel bearing is not decided by front versus rear. The same two numbers cover both, split only by inner ring length.
The rear listing stops a year short of the front. On a 2016 car the rear must be matched to the old part or the VIN.
Year by year
2010 through 2015 run the same rule at both ends: 15mm means 513301, 19mm means 512574.
2016 keeps that rule at the front but drops it at the rear.
A 2013 Audi S4 wheel bearing sits safely inside the stable window, front and rear alike.
B8 and B5, two eras of S4
This 2010-2016 car is the B8 generation S4, distinct from the earlier B5 car covered on the 2000-2002 Audi S4 wheel bearing page.
Cars built just before this run, 2007-2009, fall under a separate 512305 hub listing rather than these rows.
Treat each era as its own lookup rather than assuming one table covers the whole S4 name.
Diagnosing an Audi S4 wheel bearing
- Listen for the noise. A worn bearing usually growls or hums, and the pitch tracks road speed, not RPM. Wheel bearing noise on turns covers the pattern.
- Rule out the tires. Uneven tread wear can sound like a failing bearing. Tire noise or wheel bearing helps tell them apart.
- Check for play. With the wheel off the ground, rock it top and bottom to feel for looseness. How to check a wheel bearing walks through it.
- Measure before ordering. Pull the old bearing and check the inner ring length: 15mm means 513301, 19mm means 512574.
- Match the old part on a 2016 rear. With no documented number for that position, use the old bearing’s markings or the VIN.

What wheel bearing does a 2016 Audi S4 use?

Does the front and rear use different numbers?
No. The same two numbers, 513301 and 512574, serve front and rear, split by inner ring length rather than position.
Why does the rear stop being documented before the front?

Are 2007-2009 S4 numbers the same as this table?
No. Those years fall under a separate 512305 hub listing, not the 2010-2016 rows here.
