Mevotech Supreme Wheel Bearing and Hub Assembly P/N:MB50319
Replace a growling 2004-2010 Toyota Sienna wheel bearing at the rear wheel end with the Mevotech Supreme Wheel Bearing and Hub Assembly, MPN H512281. It installs as a direct-fit rear replacement for the 2004-2010 Toyota Sienna — see the Buyer's Guide tab for engine-level fitment.
Mevotech states high-grade materials are used across all components for longer part life, and cites extensive in-house and third-party durability testing. Signs the original may need replacing include a humming or growling that changes with speed or a rear-wheel wobble. If a failed rear wheel bearing and hub assembly is the cause, this replaces it. Replacing the matching side at the same time is good practice for balanced performance.
What vehicle does the H512281 hub assembly fit?
It is a direct-fit rear wheel bearing and hub assembly for the 2004-2010 Toyota Sienna. Check the Buyer's Guide tab to confirm engine-level fitment for your exact vehicle.
Is this a front or rear wheel bearing?
This assembly is cataloged for the rear position on the listed applications.
Does it come pre-filled with grease?
Yes. It is pre-filled with a premium lubricant designed to withstand high temperature and extreme pressure while resisting corrosion and reducing friction.
How do I know if my wheel bearing is bad?
Common signs include a humming or growling that changes with speed or a rear-wheel wobble. Diagnose the cause first, since these symptoms can have other sources.
Should I replace both sides at once?
It is sold individually. Replacing the matching side at the same time is good practice for balanced, even performance, though not strictly required.
