The short version
- A Tundra wheel bearing at the front is unusually simple to order. One number covers a long run of years.
- 515103 is commonly cited from 2007 all the way to 2019. Diagnosis matters more here than ordering does.
- The rear is not one flat story. It splits in 2007, from a plain axle bearing to a handed bolt on hub.
- 512352 is the left rear from 2007 on, and 512351 is the right.
Most pages on this site exist to prevent an ordering mistake. The Tundra front barely offers one, across 2000 to 2019. One number covers most of the truck’s life, which is unusual for anything this size.
The rear is a different story. It changed design partway through, and the older three row summary on this page flattened that change. That flattening is the main thing this rewrite corrects.
This page runs the full 2000 to 2019 span with real numbers at every year. The work here is depth, not filling gaps. Every position below traces back to a catalog line, not a guess.
The Tundra wheel bearing ordering picture
The commonly cited front hub number spans 2007 to 2019 on these trucks. That is unusual across any manufacturer.
Confirm against the number on the old part, but expect the front to be simple. The harder question is whether it needs replacing at all.
Neither drivetrain, cab style nor wheel size splits the front number in any catalog checked for this page. Lookups still run through the cross reference page.
A second catalog lists its own cross number for the front hub, WE60786. It matches the same 2007 to 2019 span. That is a parallel listing, not a correction.
A separate Timken entry covers 2007 and 2008 two wheel drive trucks with its own module number. It sits alongside the main number rather than replacing it.
The same front number also covers the Land Cruiser and the Sequoia for the years the three trucks share this platform. That kind of cross model listing is common on a hub this size. It still has to match by number, not by badge.
A single number covering this many model years also means the aftermarket has had more time to build out cheaper options for it than for most trucks. That keeps the front inexpensive relative to the rest of what a Tundra costs to maintain.
What is actually inside the 2000 to 2006 front
Before 2007 the front is a serviceable setup, not a sealed hub. An inner bearing and an outer bearing each press into the hub separately.
An inner seal and an outer seal complete the set. The kit number 517011 groups the seals, while the bearings are ordered on their own.
On four wheel drive trucks the inner seal carries its own number, 710570. Two wheel drive trucks share the same outer seal, 710571, without that inner seal.
Fitting one of these correctly takes a press, unlike the sealed hub that came after it. More on that tool is on the press in page.
A second catalog gives the bearings their own numbers too, WE60814 for the outer and WE60714 for the inner. Those sit alongside the National seal numbers above, not in place of them. Matching either set to the part coming off the truck works the same way.
2007 is the clean break between the two designs. Nothing about the serviceable set carries forward past that year on this page.
The rear splits in 2007, not before
From 2000 to 2006 the rear is a genuine solid axle bearing. The bearing rides in the housing with the shaft passing through it. There is no hub number to order.
From 2007 the rear changes to a handed bolt on hub assembly instead. 512352 is the left side and 512351 is the right, confirmed across three separate catalogs.
Older pages call the whole 2000 to 2019 rear a plain axle job. That description is only right for the first seven years. The 2007 change is a real design change, not a rebrand of the same part.
What an axle bearing job actually involves, versus a hub swap, is on the axle bearing page. What differs between front and rear in general is on the front versus rear page.
Moog, National and BCA were all checked separately for this split. Each one draws the 2006 to 2007 line in the same place, which is why it is treated as settled rather than as one catalog’s opinion.
The left and right numbers stay flat from 2007 all the way to 2019 in every catalog checked. Nothing about cab style, drivetrain or bed length moves either number in that span. Confirming left from right is the only real decision left at the rear.
A dedicated seal number, NS710576, rides with the newer rear hub as well. It is worth replacing alongside the hub rather than reusing the old one.
The older 2000 to 2006 axle carries its own seal numbers, separate from anything in the hub era after it. The inner seal is NS710649 and the outer is NS710574. Neither one interchanges with the newer hub’s seal.
Because ordering is easy, diagnose properly
Aggressive tread on a heavy truck hums in a way that rises with speed. So does a failing bearing.
The separator is road surface. Tire noise changes note between concrete and asphalt, and a bearing does not.
Those checks are on the tire noise page and the checking page.
A worn wheel bearing rarely announces itself with anything beyond noise and heat on this truck. It does not typically loosen the wheel the way a failing ball joint can. That keeps the diagnosis narrow once the tires are ruled out.
What shortens a Tundra wheel bearing
Towing and payload shorten bearing life more than mileage alone does. A truck worked hard at low mileage can wear out a bearing before one driven gently at high mileage.
That holds at both ends, front and rear alike, across every year on this page.
Larger tires and wheel spacers add to the same problem. Both move the contact patch further out and lengthen the lever the bearing has to resist.
A truck kept stock and driven mostly empty sits at the low end of this wear curve. One pushed toward its rated tow capacity on a regular basis sits at the high end. Both trucks still take the same part number for their year.
None of that changes which number gets ordered. It only changes how soon the part wears out.

Every model year this chart resolves: 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 and 2019.
An earlier version of this page had only three rows. It called the entire 2000 to 2019 rear a plain solid axle with no number to order. Three separate catalogs agree that description stops being accurate after 2006.
From 2007 the rear is a handed bolt on hub, left and right. Three separate sources confirm it, not one. Match the year to the correct era before assuming the older axle description still applies.
Diagnosing a Tundra wheel bearing
- Change road surface at a steady speed, which separates tires from the hub.
- Rock the wheel at twelve and six with it raised.
- Weave at road speed to see whether the noise follows load to one side.
- Coast in neutral for a rear noise, to separate the differential.
- Compare hub temperatures after a drive across each axle.
Pricing the job once it is confirmed is on the quote page. Front and rear both bolt on complete from 2007, so the parts cost is the main variable between the two. Confirming which end is at fault first keeps the quote from covering both when only one needs it.

Common questions
Which Tundra wheel bearing do I need?
The front is commonly cited as 515103 across 2007 to 2019. The rear depends on year: an axle bearing job through 2006, then 512352 left or 512351 right from 2007 on. Confirm the year before assuming either era applies.
Can the front be repacked?
Only on 2000 to 2006 trucks, which use a serviceable bearing set. From 2007 it is a sealed hub replaced complete, with nothing to service inside it. Repacking calls for cleaning and greasing both tapered races rather than swapping a sealed cartridge.
Is the rear the same job every year?
No. Through 2006 it is an axle bearing in the housing, with the shaft coming out as part of the job. From 2007 it is a bolt on hub, left and right, replaced complete like the front.
Do I need a press?
For the front on 2000 to 2006 trucks, yes. Every other position on this page bolts on. Confirm the year first, since the boundary falls exactly at the 2007 model year.
Is it the bearing or the tires?
Change road surface at a steady speed. Tire noise changes note between concrete and asphalt, and a bearing does not. Rocking the wheel while it is raised is the other quick check.
