515040 Front Wheel Hub Bearing Assembly for Toyota Tacoma 4Runner

In this review of the 515040 front wheel bearing hub assembly for Toyota and Lexus models, the bottom line is simple: this replacement unit is for owners who need a direct-fit, sealed hub that restores wheel rotation and ABS sensor function without complicated bearing preload adjustments. It is most useful when a worn hub is causing noise or looseness and the vehicle is listed in the compatibility notes. Installation is straightforward for a competent DIYer or a mechanic and the design aims to reduce vibration and noise compared with older or damaged hubs.

Key Features

• Direct fit compatibility: Designed to match Toyota 4Runner, FJ Cruiser, Tacoma and Lexus GX models listed in the product notes, reducing fitment guesswork.
• Sealed bearing construction: Well sealed bearings help keep contaminants out, which supports longer service life under normal conditions.
• High load capacity: Compact structure with higher load-bearing capability helps maintain wheel alignment and smooth rotation under load.
• Integrated ABS sensor: Includes magnetic coding ring and ABS sensor compatibility, preserving anti-lock braking system function.
• Easy installation:
No bearing clearance adjustment is required during installation, simplifying fitment for installers.

Who It's For

This hub assembly is aimed at owners of 4WD Toyota 4Runner (2003-2021), FJ Cruiser (2007-2014), Tacoma (2005-2021) and Lexus GX460/GX470 models who need a straightforward replacement for a failed or noisy front hub. It is suitable for home mechanics with basic tools as well as professional shops because it installs without adjusting bearing clearance.

Drivers who require OEM-grade, long-term durability under heavy off-road use or who prefer branded dealer parts may want to consider OEM hubs as an alternative. Also, vehicles that need a non-magnetic ABS ring or a different bolt pattern should confirm OE interchange numbers before purchasing.
