Home › Vehicles › Infiniti › Infiniti I30 and I35 Wheel Bearing Part Numbers
The short version
- The Infiniti I30 wheel bearing splits at the 2000 model year. Earlier cars use a front inner ball bearing, later ones use a full front hub assembly.
- That same hub assembly, HA590600K, carries forward into the I35 from 2002 through 2004.
- The rear hub for 2000-2004 is 512203. The 1996-1999 rear has no clean catalog row: match the old part or the VIN.
- The I30 and I35 share their platform with the Nissan Maxima A32. Maxima charts fill gaps the Infiniti listings leave open.
Infiniti sold the I30 as a rebadged Maxima. It later renamed the car I35 for its final three years without changing much underneath. The Infiniti I30 wheel bearing catalog reflects that shared identity more than it reflects two separate cars.
Two eras, one shared hub
Cars built from 1996 through 1999 use a front inner ball bearing, 510009, the same part fitted to the Maxima A32 of that generation. From 2000 onward the front switches to a complete hub assembly, HA590600K.
That hub assembly number does not reset when the car became the I35 in 2002. It carries straight through to 2004.

Lookups run through the cross reference page.
The rear hub for 1996 through 1999 I30s has no clean row in the catalogs. Match the old part or confirm by VIN, using the Maxima A32 rear chart as a reference since the two cars share a platform.
Do not assume the 2000-2004 rear number, 512203, reaches backward into the earlier cars. Nothing in the catalogs supports that.
Built on the Maxima A32 platform
The I30 was Infiniti’s version of the Nissan Maxima, sharing the A32 platform and much of the running gear underneath the trim differences. That relationship holds for the I35 too, since it replaced the I30 without a platform change.
Owners chasing an obscure number can often find it faster on the Maxima side of the catalog. Then confirm it applies to the Infiniti equivalent.
Where the I30 sits in the Infiniti lineup
The I30 and I35 were Infiniti’s midsize sedans, positioned below the larger Infiniti Q45 flagship. Infiniti eventually replaced the nameplate with the Infiniti G35, a different platform with its own part numbers.
None of that lineage changes what fits an I30 or I35 directly. Use it only to understand why the catalogs group these cars together.
Diagnosing an Infiniti I30 wheel bearing
- Listen for a speed-linked hum. A worn bearing gets louder as road speed increases, not with engine RPM.
- Turn the wheel while listening. Loading the bearing through a turn often makes the noise more obvious on one side.
- Jack up the corner and rock the wheel. Check for play at 12 and 6 o’clock with the wheel off the ground.
- Spin the wheel free. Grinding or roughness while spinning by hand points at pitted races.
- Confirm the year before ordering. The front number changes at 2000, so verify the model year and whether the car is badged I30 or I35.
Common questions
What is the Infiniti I30 wheel bearing part number?
For 1996 through 1999 it is front inner ball bearing 510009. From 2000 on, the front switches to hub assembly HA590600K, which continues into the I35.
Do I30 and I35 wheel bearings interchange?
Yes, for the front hub assembly. Both use HA590600K from 2000 through 2004, since the I35 continues the same platform under a new name.
What is the rear wheel bearing on an I30?
For 2000 through 2004 it is 512203. For 1996 through 1999, match the old part or the VIN, since there is no clean rear listing.
Does the I30 wheel bearing match the Nissan Maxima?
The I30 shares its platform with the Maxima A32. The front bearing number for 1996-1999 cars is the same part used on that Maxima.
Is the Infiniti I30 wheel bearing a sealed hub assembly?
Only from 2000 onward. Earlier cars use a separate inner ball bearing rather than a complete bolt-on hub unit.
