Detailed Description

InMotion WA515050HD is a front wheel bearing and hub assembly designed for select 2002-2005 Ford Explorer, 2003-2005 Lincoln Aviator, and 2002-2005 Mercury Mountaineer models. It uses a roller bearing design, a 27-spline hub, and an integrated ABS sensor with a tone ring to support proper wheel speed signal operation. The assembly is manufactured to OE measurements, with a 114.3 mm hub centerbore, 12.7 mm flange bolt size, M12-1.75 lug bolt thread size, and a 1/2"-20 flange bolt thread size for application-specific fitment.

This part cross-references MOOG 515050 and SKF BR930456 for the same application.

Common Replacement Reasons

• Wheel bearing noise from the front hub area
• ABS warning light caused by a failed sensor or tone ring issue
• Excessive front wheel play or looseness
• Uneven hub rotation or rough bearing feel
• Vehicle vibration related to hub wear

Installation Notes and Tips

Confirm front-position fitment and verify the 27-spline, driven-application configuration before installation. Inspect the knuckle mounting points, axle interface, and ABS wiring harness routing during replacement. Because this assembly includes the ABS sensor and harness, make sure the connector style and harness length match the vehicle layout before final torqueing.
