The short version
- A 2002 Mitsubishi Lancer wheel bearing replacement depends on trim first. ES sedans, the LS and SE group, and AWD models each carry different numbers.
- ES front hubs were superseded: 510021 came first, then 510061 replaced it.
- LS, SE, O-Z Rally, Ralliart, and Sportback trims share one front number, 510079.
- AWD models use their own pair, 513133 front and 512181 rear, from 2003 through 2006.
Mitsubishi sold the Lancer from 2002 through 2007 across several trims. Trim decides the wheel bearing here more than model year does.
2002 Mitsubishi Lancer wheel bearing replacement numbers at a glance
The ES front hub was superseded partway through this run, from 510021 to 510061.
Every other gas trim shares one front number, while AWD models use a separate pair entirely.

This page covers the 2002-2007 Mitsubishi Lancer: 2002, 2003, 2004, 2005, 2006, 2007. Other years live on the main Lancer wheel bearing page.
Trim decides nearly everything on this Lancer. The ES front hub was superseded: 510021 replaced by 510061. Match the old part rather than picking a number at random.
LS, SE, O-Z Rally, Ralliart, and Sportback trims share 510079 up front. The rear still splits by trim group, though.
AWD models from 2003 through 2006 use their own front and rear pair, 513133 and 512181. That pair is separate from every gas trim front listing.
Year by year
2002 and 2003 run the base rows. That means the ES front pair, the shared 510079 front, and the trim split rear rows.
2004 adds the Ralliart and Sportback rear listing, 512339, alongside the existing rear rows.
AWD rows run 2003 through 2006 only. Trim still decides more than model year throughout. That is the core lesson of any 2002 Mitsubishi Lancer wheel bearing replacement.
A wide trim spread on one platform
The Lancer’s trim lineup ran from the base ES sedan to the O-Z Rally and Ralliart. That spread split the wheel bearing catalog by group rather than by year.
Consider a 2002 Mitsubishi Lancer wheel bearing replacement. The ES sedan job and the O-Z Rally job are not the same.
AWD adds a third path. It brings its own hubs at both ends.
Diagnosing a Mitsubishi Lancer wheel bearing
- Identify the trim first. ES, LS, SE, O-Z Rally, Ralliart, and Sportback each point to different rows on this page.
- Check for the ES supersession. If the old part is 510021, the current replacement is 510061.
- Confirm the drivetrain. AWD models use a separate hub pair at both ends. See how drive type affects wheel bearings for why that split matters.
- Listen for a rotating hum. A worn bearing 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. See how to check a wheel bearing for the full routine.
Common questions
What wheel bearing does a 2002 Mitsubishi Lancer use?
A 2002 Mitsubishi Lancer wheel bearing replacement depends on trim. ES sedans use 510021 or the later 510061, while LS, SE, O-Z Rally, Ralliart, and Sportback trims use 510079.
What wheel bearing does a 2005 Mitsubishi Lancer use?
A 2005 Mitsubishi Lancer follows the same trim split as 2002. It also gets the Ralliart and Sportback rear listing, 512339, added in 2004.
Why was the ES front wheel bearing superseded?
The catalogs list 510021 as the original ES front number, later replaced by 510061. Match whichever number the old part actually carries.
Does the O-Z Rally use a different wheel bearing than the LS?
No. The O-Z Rally shares its front number, 510079, and its rear number, 512277, with the LS and SE trims.
Does an AWD Lancer use the same wheel bearing as a front wheel drive Lancer?
No. AWD models from 2003 through 2006 use their own front and rear pair instead, 513133 and 512181. That pair is separate from every front wheel drive trim.
