What It Helps Address

• Wheel-end noise from a worn front outer bearing
• Excessive play or looseness at the front wheel

• Uneven wheel-end stability on heavy-duty GM trucks and vans
• Service replacement needs for Chevrolet C2500, GMC C3500, and similar front outer applications

Installation Notes

Verify the bearing dimensions, bearing type, and front outer position before installation. This part cross-references common wheel bearing applications such as Timken 15103 and National 15103 for the same service position. For best results, inspect the hub, spindle, seals, and related wheel-end components during service, and confirm brake configuration where noted, including Heavy Duty Brakes or 11,000 lb axle applications.

Quality Assurance

InMotion positions this bearing as a durable, multi-purpose component for automotive and industrial use, with materials selected for consistent rotation and long service life. WT15103S is built for dependable wheel-end performance across the listed Chevrolet and GMC front outer applications.
