The short version
- A 2008 Mercury Mariner wheel bearing order again finds two catalog designs at the front and rear, a hub listing and a National press in bearing.
- The hub listings are 515078 front and a 521000 rear repair kit, running 2008 through 2010.
- National press in bearings, 510072 front and 510029 rear, run only 2008 and 2009.
- 2011 is not documented at all: match the old part or run the VIN.
Mercury built this Mariner generation from 2008 through 2011. The catalogs thin out toward the end of that run rather than staying steady.
2008 Mercury Mariner wheel bearing numbers at a glance
The hub listing and the National press in listing are parallel designs for the same positions.

This page covers the 2008-2011 Mercury Mariner: 2008, 2009, 2010, 2011. Other years live on the main Mariner wheel bearing page.
The catalogs slice this Mariner two ways, hub listings and National press in listings. These are parallel listings, so pull the old part and match what it actually is.
Coverage thins at the end of the run. 2010 keeps only the hub listings, and 2011 is not documented at all.
A 2011 Mariner order needs the old part matched directly or the VIN run, since the catalogs stop short that year.
Year by year
2008 and 2009 carry all four rows: the hub listings and the National press in listings both apply.
2010 drops the National press in rows and keeps only the hub listings, 515078 front and 521000 rear.
2011 has no documented rows. Match the old part or run the VIN for both ends. A 2008 Mercury Mariner wheel bearing order sits at the well documented end of this range, unlike 2011.
Continuing from the earlier Mariner
This generation follows the 2005-2007 Mariner on the earlier Mariner page, which carries its own separate numbers.
Nothing from that earlier page carries forward to the rows shown here.
A 2008 Mercury Mariner wheel bearing order should use only this page’s rows.
Diagnosing a Mercury Mariner wheel bearing
- Pull the old part first. Confirm whether the vehicle has a hub assembly or a press in bearing before ordering a replacement.
- Check the model year against coverage. 2008 and 2009 have both designs listed, 2010 has only the hub, and 2011 has neither documented.
- Run the VIN on a 2011 Mariner. Since nothing is documented that year, matching the old part or the VIN is the only path forward.
- Listen for a rotating hum. A worn bearing usually hums or growls and grows louder with speed. See wheel bearing noise on turns for the pattern.
- Check for wheel play. Raise the wheel, grab it at 12 and 6 o’clock, and rock it to feel for looseness in the hub.
Common questions
What wheel bearing does a 2008 Mercury Mariner use?
A 2008 Mercury Mariner wheel bearing depends on design: the hub listing, 515078 front and 521000 rear, or the National press in listing, 510072 front and 510029 rear.
What wheel bearing does a 2011 Mercury Mariner use?
A 2011 Mercury Mariner has no documented wheel bearing rows. Match the old part or run the VIN instead of guessing a number.
Why did the National press in listing stop after 2009?
The catalogs simply do not carry that press in listing past 2009. From 2010 on, only the hub listing is documented.
Should I use the hub listing or the press in bearing on my Mariner?
Pull the old part and match what it actually is. These are parallel listings for the same position, not a free choice between two options.
Is this the same Mariner as the 2005-2007 model?
No. The 2005-2007 Mariner is a different generation with its own page and its own separate wheel bearing numbers.
