Home › Vehicles › Subaru › Subaru WRX › 2008-2014 Subaru WRX Wheel Bearing Part Numbers
The short version
- A 2013 WRX wheel bearing up front is 513303 on the base car, 513302 on the STI, unchanged all seven years.
- The rear runs mostly 512401 on WRX through 2013, with 512402 listed as an optional STI line through 2012.
- 2014 flips that pattern: the STI keeps 512401, and the base WRX moves to 512402.
- Treat any 2013 or 2014 rear order as a conflict and match the number the old part carries.
This page covers the 2008 to 2014 Subaru WRX. A 2013 WRX wheel bearing job up front is simple, 513303 base or 513302 STI. The rear gets complicated by year and trim.
The core numbers for this WRX
The rear stays simpler through 2012, mostly 512401 on WRX with an optional STI listing, 512402.
2013 and 2014 rear numbers do not follow a clean pattern. Match the old part rather than guessing by trim alone.

This page covers the 2008-2014 Subaru WRX: 2008, 2009, 2010, 2011, 2012, 2013, 2014. Other years live on the main Subaru WRX wheel bearing page.
In 2013 both WRX and STI rear listings sit under 512401. In 2014 the STI keeps 512401, but the base WRX moves to 512402.
Treat this as a catalog conflict, not a running change. Match the number the old part carries rather than assuming trim alone decides it.
Year by year
2008 through 2014 keeps one front number per trim. WRX uses 513303 and STI uses 513302, with no changes.
2008 through 2012 rear numbers run mostly on 512401 for WRX. 512402 shows up as an optional line for STI and some trims in that same span.
2013 rear listings bring WRX and STI together under one number, 512401.
2014 splits them again, but backward from what 2012 suggested: STI stays on 512401, WRX moves to 512402. A 2013 or 2014 rear job should match the old part rather than assume the pattern held.
An all wheel drive platform, front to rear
This WRX generation runs all wheel drive. Both ends carry constant load, part of why a 2013 WRX wheel bearing order needs care about trim on the rear.
The 2015 to 2021 WRX moved to a new generation with its own numbers, covered on the 2015 to 2021 page. Drivetrain layout shapes wear patterns on both bearings, covered on drive type and wheel bearings.
Diagnosing a Subaru WRX wheel bearing
- Listen for a speed sensitive hum. A worn bearing changes pitch with road speed, detailed on the wheel bearing noise turning page.
- Check both front corners. All wheel drive puts steady load on both sides, not just one.
- Check the rear too. A 2013 WRX wheel bearing job on the rear needs extra care. This platform loads the rear more than a front drive car would.
- Run through a basic inspection. A simple checklist helps before buying parts, covered on how to check a wheel bearing.
- Set preload correctly on reinstall. Getting this wrong shortens bearing life fast, covered on preload and end play.
Common questions
What wheel bearing does a 2008 Subaru WRX use?
A 2008 WRX front uses 513303, and the STI front uses 513302. The rear that year uses 512401 on WRX, with 512402 listed as an optional STI line.
What wheel bearing does a 2013 WRX use?
A 2013 WRX wheel bearing up front is 513303. The rear that year uses 512401 on both WRX and STI.
Why does the 2014 rear number depend on trim?
The catalogs print the STI and base rear numbers opposite to how 2013 listed them. Confirm the trim and match the old part before ordering a 2014 rear bearing.
Are the front and rear bearings interchangeable between WRX and STI?
No. The front numbers are trim specific, 513303 WRX and 513302 STI, and never cross between them.
Why do rear listings mention an optional number?
Some years carry two parallel listings for the rear, one main and one optional for certain trims. Match the number the old part carries rather than picking either one at random.
