Home › Vehicles › Infiniti › Infiniti Q50
The short version
- A Q50 wheel bearing at the front splits on drivetrain, 513334 for rear wheel drive and 513335 for all wheel drive.
- Those two numbers cover most of the Infiniti range, so the model name narrows very little.
- 512379 is cited for the rear across 2014 to 2018.
- The badge changed from G to Q in 2014, so older listings for the same hardware say G37.
Infiniti renamed its entire range in 2014. The cars barely changed, the names changed completely, and parts listings have been catching up ever since.
The drivetrain split
513334 is cited for rear wheel drive and 513335 for all wheel drive across 2014 to 2018.
An all wheel drive car has a driveshaft running forward from the transmission. Look before ordering.

The renaming problem
This car replaced the G37 and carries the same hub numbers, so a great many listings and threads still file it that way.
Search both names when the market looks thin under one.
The earlier cars and the wider Infiniti number family are covered on the G35 page.
One hub, most of the brand
513334 turns up under the G25, G35, G37, M37, M45, Q40, Q60, Q70, EX35, FX35, FX37 and QX50, and under the Nissan 370Z as well.
512379 covers a similarly wide spread at the rear. So a listing aimed at a completely different Infiniti is very often the part you need.
Check the number rather than the vehicle name in the title.
What owners do to these
A large share run lowered suspension, aggressive camber and wider wheels with more offset.
All three move load away from where the bearing was designed to take it. Static negative camber is the quiet one, working on the inner races on every drive.
Those are on the spacers page and the failure page. The make overview is on the Infiniti page.
Diagnosing a Q50 wheel bearing
- Confirm the drivetrain before ordering a front part.
- Search under G37 too, since the numbers carried over.
- Coast in neutral, since a rear drive driveline makes noises of its own.
- Weave at road speed and note the loaded direction.
- Check the camber and wheel setup, because both change what is likely.
Those are on the checking page and the tire noise page.
