Detailed Description

Built from high-quality materials, this InMotion wheel bearing is made for rotational support, reduced friction, and stable operation in demanding automotive and industrial environments. The taper bearing profile and listed dimensions make WT3994 a practical choice for rear inner wheel bearing replacement on Ford F-250 and Ford F-350 trucks where the specified axle and ring gear configuration applies. WT3994 is a service part that supports smooth wheel rotation and consistent load handling in driveline applications.

What It Helps Address

• Wheel end noise from a worn rear inner bearing
• Excessive friction in the hub and axle assembly
• Loose or unstable wheel rotation
• Service replacement for worn bearing surfaces
• Reduced rotational efficiency in rear axle service

Installation Notes and Tips

• Verify axle configuration before ordering; this listing includes 1985-1999 Ford F-250 rear inner with 10.25-inch ring gear and 1985-1997 Ford F-350 rear inner.
• Confirm bearing dimensions against the removed part: 2.625-inch inside diameter and 1.183-inch width.
