The short version
- MR2 wheel bearing numbers split by era and by end, not by side alone.
- 1990 to 1995 Turbo era: front 513022, rear 510006, both press-in.
- 1999 to 2005 Spyder: front hub HA595017, bolt-on, rear 510070 press-in, the same ball bearing the Corolla and Matrix fronts use.
- The mid engine layout puts more of the car’s weight over the rear bearings than a front engine Toyota ever does.
Toyota built the MR2 with the engine sitting behind the driver and ahead of the rear axle. That single layout choice quietly rewrites which end of the car does the heavier bearing work. An MR2 wheel bearing job reads the corners in reverse order from a front engine Toyota.
The core MR2 wheel bearing split
The 1990 to 1995 Turbo era pairs front 513022 with rear 510006, both press-in.
The 1999 to 2005 Spyder swaps to a bolt-on front hub, HA595017, with a rear press-in ball bearing, 510070.

Lookups run through the cross reference page.
The front end changes construction entirely, from a press-in bearing on the Turbo era car to a bolt-on hub assembly on the Spyder.
Rear numbers look similar on paper, 510006 versus 510070, but they belong to different years and are easy to transpose by mistake.
A mid engine car with a Corolla in the family tree
The Spyder’s rear press-in bearing is 510070. That is the same ball bearing used at the front of the Toyota Corolla and the Toyota Matrix.
Toyota simply reused a high volume part rather than engineering something MR2 specific. That keeps a Spyder MR2 wheel bearing cheap despite the car’s sports car billing.
A rear corner doing a front corner’s job
A front engine car sends most of its weight to the front bearings under braking and cornering load. The MR2 flips that. The engine sits over the rear axle and loads the rear bearings the way a front bearing usually works.
That is worth remembering when a rear MR2 wheel bearing wears faster than expected. The corner is doing a front corner’s job instead.
A front engine Toyota, like the Toyota Celica, sends that same burden to the front end instead.
Diagnosing an MR2 wheel bearing
The general method sits on the how to check a wheel bearing page. Broader Toyota coverage lives on the Toyota wheel bearing index. The steps below are MR2 specific.
- Listen for a growl that builds with road speed. A worn MR2 wheel bearing produces a steady drone that climbs with speed, not engine RPM.
- Note which corner gets louder in a turn. A change in volume during a lock to lock sweep points at a specific corner. That detail is covered on the noise in turns page.
- Check for play at the rear corners first. The mid engine layout puts more load on the rear bearings. Rear play often shows up before the front does.
- Rule out tire noise before condemning the bearing. A cupped tire can mimic bearing drone at highway speed, so compare against the tire noise checklist first.
- Spin each wheel by hand off the ground. Roughness or resistance while turning the hub confirms a bearing problem rather than a brake drag.
Common questions
Does the MR2 wheel bearing number change between the Turbo era and the Spyder?
Yes. The Turbo era pairs front 513022 with rear 510006. The Spyder switches to front hub HA595017 and rear 510070.
Does the Spyder’s rear wheel bearing really match a Corolla part?
Yes. The Spyder’s rear press-in bearing is 510070. That is the same ball bearing used at the front of the Toyota Corolla and Toyota Matrix.
Why does the MR2’s mid engine layout matter for the rear bearing?
The engine sits over the rear axle instead of the front. The rear bearings carry a share of the load a front bearing normally handles. That extra duty can show up as earlier wear at the rear corners.
Is the Spyder’s front hub the same style as the Turbo era front bearing?
No. The Turbo era front is a press-in bearing. The Spyder front is a bolt-on hub assembly, and the two do not interchange.
What years count as the MR2 Turbo era for parts purposes?
1990 to 1995 covers the Turbo era front and rear numbers used on this page. The 1999 to 2005 Spyder is a separate generation with its own numbers.
