2020-2026 Duramax Wheel Bearing Assembly (AX515208)

OE wheel bearings on the new GM HDs don’t hold up to towing, big tires, or a lifted setup — they get sloppy, kill steering feel, and chew up your brakes. The Axiom assembly is a complete bolt-in fix with a tighter hub structure, Grade 10.9 hardware, and an ABS sensor that survives the real world. Two-hour install, left or right side, no special tools.
