The short version
- Previa wheel bearing assembly 517003 fits front and rear alike, one number for the whole van.
- Inner seal 225678 and outer seal 226150 go with that bearing at every corner.
- Toyota built the Previa as a mid engine van, with the engine sitting under the front seats between the axles.
- These bearings are serviceable, so they get repacked and adjusted rather than pressed and replaced whole.
Toyota tucked the Previa’s engine under the front seats, an odd home for a minivan powerplant. The egg shaped van joins a short list of vehicles that use exactly one bearing number at every wheel. A Previa wheel bearing job looks more like servicing a work truck than a modern minivan.
The one Previa wheel bearing number
Inner seal 225678 and outer seal 226150 complete the assembly at each corner.
One part number covering both ends of the van is unusual. It says something about how Toyota built this generation.

517003 covers both ends of the Previa, and there is no second listing hiding for the opposite end.
The two seals, 225678 inner and 226150 outer, are not interchangeable with each other, so keep them straight when ordering.
A serviceable design in a minivan body
A single bearing assembly number covers front and rear alike. That puts the Previa closer to a truck bearing setup than to a modern Toyota Sienna. Later minivans mostly moved to sealed, non serviceable hubs.
The Previa instead asks an owner to repack and adjust the bearing by hand. That is the same routine long associated with the Toyota Land Cruiser and other truck based Toyotas.
Built for adjustment, not replacement
A serviceable bearing means service intervals matter. The wheel bearing adjustment procedure sets bearing preload by hand. That is different from trusting a sealed cartridge to get it right at the factory.
A loaded minivan carries real vehicle weight. Toyota’s engineers built the Previa’s hub around that reality. Sealed, low maintenance designs did not arrive on this van until much later.
Diagnosing a Previa wheel bearing
The general method sits on the how to check a wheel bearing page. The steps below account for the Previa’s serviceable design.
- Listen for a hum that grows with road speed. A worn bearing produces a steady drone that climbs with speed rather than engine RPM.
- Check whether the noise shifts in a turn. A change in volume during a lock to lock sweep points at one corner. That pattern is covered on the noise in turns page.
- Jack each corner and check for play. Grip the tire at three and nine o’clock and rock it. Looseness in a hub that should sit solid points to the bearing.
- Watch for a rough or notchy feel while spinning the wheel. That texture points to bearing wear rather than a brake or suspension issue.
- Check the seals for grease weeping past the hub. A worn or poorly seated seal, inner or outer, lets grease escape and lets water in.
Common questions
Is there a separate front and rear Previa wheel bearing number?
No. The same assembly, 517003, covers both the front and rear wheels on the 1991 to 1997 Previa.
What seals go with the Previa wheel bearing assembly?
Inner seal 225678 and outer seal 226150 accompany the 517003 bearing at each corner. Keep the two straight since they are not interchangeable.
Does the Previa wheel bearing need to be repacked?
Yes. It is a serviceable design, so it gets repacked and adjusted rather than pressed in and replaced whole.
Why does a minivan use a truck style serviceable bearing?
The Previa dates to a period when Toyota still built many vehicles with adjustable, hand packed bearings. The design carried over into this van rather than being replaced with a sealed hub.
What does a failing Previa wheel bearing sound like?
Expect a low speed hum that grows louder with road speed and often shifts volume in turns. Rocking a jacked wheel by hand for play is a quick way to confirm it.
