Detailed Description

This InMotion wheel bearing and hub assembly is built for front-end service on the Ford F-250 Super Duty and Ford F-350 Super Duty. The design follows OE measurements to support proper fitment, wheel mounting, and hub alignment, making WA515021 a practical replacement when servicing the front wheel end on 1999-2001 Ford F-250 Super Duty and 1999-2001 Ford F-350 Super Duty trucks.

• Front hub replacement needs on Ford Super Duty trucks
• Fitment issues when replacing an OE-style hub assembly

Installation Notes

Confirm that the vehicle uses the listed front application for 1999-2001 Ford F-250 Super Duty or 1999-2001 Ford F-350 Super Duty. The anti-lock brake sensor is not included, so reuse or source the correct sensor arrangement as required by the vehicle.
