Home › Vehicles › Audi › Audi A4 › 1996-2001 Audi A4 Wheel Bearing Part Numbers
The short version
- The 1996 to 2001 Audi A4 presses in every wheel bearing it has, and the 2001 Audi A4 rear wheel bearing on a quattro car is 510020, the same number used up front on four cylinder cars.
- Four cylinder fronts run 510020 all six years, V6 fronts run 510019 from 1997 on.
- 1996 V6 cars split into two front designs mid year, 510069 first, then 510019.
- Front wheel drive rears are not documented in the catalogs we hold, so match the old part or run the VIN.
This page covers the 1996 to 2001 Audi A4, and the numbers here move around in a way that trips people up. A 2001 Audi A4 rear wheel bearing is not always a rear number in spirit. On a quattro car it is 510020, the exact figure a four cylinder car uses up front.
Audi A4 press in wheel bearing numbers
510020 covers the four cylinder front for all six years and doubles as the quattro rear for all six years. 510019 covers the V6 front from 1997 on.
1996 V6 cars are the exception, splitting into 510069 for an early design and 510019 for a later one. Every position here is a press in wheel bearing, not a bolt on hub.

This page covers the 1996 to 2001 Audi A4: 1996, 1997, 1998, 1999, 2000, 2001. Other years live on the main Audi A4 wheel bearing page.
Everything on this car presses in, and the same two numbers shuffle positions depending on the car. 510020 is the four cylinder front and, separately, the quattro rear.
1996 V6 cars split into two designs mid year. Never order by position memory alone. Match the number the old part carries.
Year by year
1996 is the split year: V6 fronts start on 510069, then move to 510019 partway through the model year. Four cylinder fronts and quattro rears already read 510020.
1997 through 2001 settle down by engine. Four cylinder fronts and quattro rears stay on 510020, V6 fronts run 510019.
Front wheel drive rears are an honest gap across all six years. A 2001 Audi A4 rear wheel bearing on a front wheel drive car has no documented number, so match the old part or run the VIN.
Quattro and front wheel drive rears on the same body
This body was sold with both quattro and front wheel drive, and the two rear axles are not related parts. Quattro cars get a documented press in number, while front wheel drive cars fall into the gap above.
The next two generations of this car move to bolt on hubs at points documented on their own pages, at the 2002 to 2008 Audi A4 page and the 2009 to 2016 Audi A4 page.
Diagnosing an Audi A4 wheel bearing
- Confirm the drivetrain. Quattro and front wheel drive cars carry different rear parts, so check which one is under the car before ordering.
- Listen for a hum that grows with speed. A press in bearing failing tends to growl and rise in pitch as speed climbs.
- Separate it from tire noise. Read tire noise versus a wheel bearing before assuming the hub.
- Check for play at the wheel. Follow the standard wheel bearing check with the car safely raised.
- Match the old part. On a 1996 V6 or an undocumented rear, read the number stamped on the bearing you pull rather than guessing from the year alone.
Common questions
What is the 2001 Audi A4 rear wheel bearing number?
On a quattro car, a 2001 Audi A4 rear wheel bearing is 510020, the same press in number used up front on four cylinder cars. Front wheel drive rears are not documented, so match the old part or run the VIN.
What wheel bearing does a 1997 Audi A4 V6 use?
A 1997 V6 front takes 510019. The four cylinder front and the quattro rear both use 510020 that same year.
Why does one number cover both a front and a rear position?
The catalogs document 510020 twice, once for the four cylinder front and once for the quattro rear. It is the same physical part serving two different corners of the car.
Why did 1996 V6 cars get two different front numbers?
The catalogs show a mid year design change on V6 fronts, from 510069 to 510019. Match the number the old part carries rather than guessing by build date.
Is there a listed rear number for front wheel drive A4 models?
No. The catalogs we hold stop short for that position, so match the old part or run the VIN instead of guessing.
