Home › Vehicles › Toyota › Toyota 4Runner › 2003-2009 Toyota 4Runner Wheel Bearing Part Numbers
The short version
- A 2005 Toyota 4Runner wheel bearing job covers 2003-2009: front hub 515040, rear hubs handed, left 512227 and right 512228.
- This generation moves to a bolt-on front hub, a change from the serviceable front on the truck before it.
- Rear hubs are handed. Left and right carry different numbers and do not swap sides.
- The rear numbers keep running past this generation, documented all the way to 2019.
2003-2009 is when the 4Runner front end switches from a serviceable bearing to a bolt-on hub. A 2005 Toyota 4Runner wheel bearing job at the front means swapping a hub assembly, not repacking a race.
The core numbers
Front: hub assembly 515040 (Moog and National), or bearing module BM500007 (Timken).
Rear: hub 512227 on the left, hub 512228 on the right. They are handed and not interchangeable.

This page covers the 2003-2009 Toyota 4Runner: 2003, 2004, 2005, 2006, 2007, 2008, 2009. Other years live on the main 4Runner wheel bearing page.
The rear hubs are handed. Left is 512227 and right is 512228, and ordering the wrong side will bolt up but will not seat correctly against the axle flange.
515040 and BM500007 are parallel front listings from National and Timken for the same position. Match the number the old part carries when replacing the hub.
Year by year
2003 through 2009 use the same front hub listing without a break. A 2005 Toyota 4Runner wheel bearing at the front is identical to a 2003 or 2009 truck.
The rear hub numbers, 512227 left and 512228 right, hold across this generation and keep running past it into the truck built after this one.
Nothing in the front or rear listing changes mid-cycle for this seven year run.
Where this generation sits in the lineup
This body replaces the serviceable front bearing found on the 1996-2002 4Runner with a bolt-on hub, and its rear hub numbers carry into the 2010-2019 4Runner.
The front hub here is also shared with the FJ Cruiser, which is why National catalogs the same assembly across both trucks.
Diagnosing a 4Runner wheel bearing
- Listen for a speed-sensitive hum. A failing hub bearing changes pitch with road speed and often grows louder in a curve.
- Jack up the affected corner. Grip the tire at 12 and 6 o’clock and rock it to check for play at the hub.
- Spin the wheel and feel for roughness. A grinding or notchy feel through the spin points to a damaged hub bearing.
- Isolate front from rear. Since these hubs are handed at the rear, note exactly which corner is noisy before ordering a part.
- Cross check with a scan tool if ABS acts up. A failing hub can throw a wheel speed fault before it gets loud.
Common questions
What wheel bearing does a 2005 Toyota 4Runner use?
