Pair 515050 Front Wheel Bearing Hub Assembly Compatible with Ford

In this review of the Pair 515050 front wheel bearing hub assembly, the bottom line is simple: it is for owners of compatible Ford Explorer, Lincoln Aviator, or Mercury Mountaineer models who need a direct-fit replacement that aims to restore handling and eliminate wheel noise. The reviewer found the assembly to be a straightforward OE-style replacement that matches listed reference part numbers and includes an ABS sensor, so it addresses both fitment and safety concerns. This is a practical choice if you want a robust hub that installs quickly and is designed to resist moisture and contamination.

Key Features

• Direct fit compatibility: Designed to match the 515050 fitment for FORD EXPLORER 2002-2005, LINCOLN AVIATOR 2003-2005, and MERCURY MOUNTAINEER 2002-2005 so replacement is intended to be plug-and-play.
• OE-style dimensions: Precision manufactured to OEM style dimensions which helps reduce the need for extra machining or modification during installation.
• ABS sensor included: The built-in ABS sensor preserves factory braking and traction systems without additional parts or wiring changes.
• Durable construction: Forged carbon steel and protective coatings improve resistance to moisture and road debris for longer service life.
• Sealed bearing design: Premium seals keep grease in and contaminants out, aiming to reduce noise and vibration over time.
• Low friction performance: Anti-shock, low friction construction helps maintain smooth wheel rotation and handling at highway speeds.

Who It's For

This hub assembly is best for DIY mechanics and professional shops working on early 2000s Ford Explorer, Lincoln Aviator, or Mercury Mountaineer vehicles that require a front left and right axle replacement with 5-lug hubs and ABS. It suits drivers noticing vibration, grease leakage, or front wheel noise who want an OE-dimensioned part to restore original function.

It is not the right choice for vehicles outside the stated year and model ranges or for owners who need a custom or performance hub that departs from OEM-style dimensions. If persistent noise remains after installation some users may need further diagnosis of brakes, suspension, or wheel balance rather than assuming the hub is faulty.

Pros & Cons

Pros

• Designed for direct fit to specified models which simplifies installation and reduces labor time.
• Includes an ABS sensor to maintain factory safety systems without extra parts.
• Sturdy forged construction and protective coating help resist moisture and extend service life.
• Sealed design aims to minimize noise and vibration when functioning correctly.

Cons

• Some users report mixed results on noise; a minority experienced continued noise after installation, so additional troubleshooting may be needed.
• Fitment depends on correct vehicle selection; incorrect match can lead to installation issues if the ConfirmedFit step is skipped.
