The short version
- 2003-2009 Nissan 350Z front hub is HA590027, a bolt-on part shared with the same-year G35 coupe.
- Rear bearing module is BM500006, also shared with the G35, also a straight bolt-on.
- The 370Z replaced the Z in 2009 and runs its own listings. Match a 370Z by VIN, not by 350Z numbers.
- A 350Z wheel bearing hum that swells through on-ramps and off-ramps deserves a same-week check, not a wait-and-see.
Nissan built the Z and the G35 coupe on the same platform, and the corner hardware carries over. Pull a hub off a 350Z and a same-year G35, and the part numbers match.
Front and rear numbers at a glance
Both numbers cover the full 2003-2009 350Z run. Both are bolt-on hub assemblies, no press or repack involved.
The same two numbers fit the G35 coupe from those years. The two cars share hub and knuckle hardware.

Lookups run through the cross reference page.
The 370Z that took over in 2009 is a different chassis under a similar name.
Its wheel bearing listings do not carry over from the 350Z numbers above. Match a 370Z by VIN rather than by these part numbers.
One platform, two badges
Nissan sold the Z as a driver’s coupe. The Infiniti G35 was its upscale twin. The corner hardware never split between the two.
Shopping both listings widens the field when you search a 350Z wheel bearing. The 240SX came before the Z on a different chassis. Its numbers do not cross with either car here.
What actually wears these out
These bearings are built for sustained cornering load, not straight line miles. That is why a Z retires them faster than an equivalent Nissan sedan does. Track days and hard on-ramp habits shorten the life of a 350Z wheel bearing well ahead of the odometer.
A pothole hit can speed that wear too, cracking a seal and letting grit into the race. Watch for a hum that changes pitch under turning load. A flat, constant hum at steady speed is more likely something else.
Diagnosing a 350Z wheel bearing
- Listen for load-sensitive noise. A worn 350Z wheel bearing hums louder through a curve and quiets on straight pavement. That separates it from tire noise.
- Compare left and right. Tire noise stays even side to side while a bad bearing usually does not.
- Jack the corner and rock the wheel. Grip it at nine and three o’clock and feel for play. See how to check a wheel bearing for the full method.
- Spin the wheel by hand. Grinding, roughness, or a grating feel points to a failing bearing rather than a brake or CV issue.
- Confirm before ordering. Match the hub or module number to the VIN and year first. Front and rear numbers are not interchangeable.
Common questions
Does a 350Z front wheel bearing fit a G35 coupe?
Yes. Both use HA590027 for the same 2003-2009 span, since the two cars share hub and knuckle hardware.
Is the 350Z wheel bearing press-in or bolt-on?
Bolt-on. Both HA590027 up front and BM500006 at the rear are complete hub assemblies. Neither is a press-in style that needs a shop press.
Do 350Z and 370Z wheel bearings interchange?
No. The 370Z carries its own listings starting in 2009. Match that car by VIN rather than reusing 350Z numbers.
What does a failing 350Z wheel bearing sound like?
A hum or drone that swells through corners and on-ramps, then eases off on straight pavement. That load-sensitive pattern is the giveaway a tire rarely produces.
Can I adjust a 350Z wheel bearing instead of replacing it?
No. These are sealed bolt-on units. There is no adjustment or repack step, only replacement of the hub or module as a whole.
