05-15103-002 or 0515103002 Meritor front hub assembly is a conventional-style, hub-only unit for a steer axle in the GM 11K 15 x 4 series, base part number 15103. It is built for a drum brake and has no tone ring. The wheel mounts with a 10 stud pattern on an 11.25 in bolt circle, and the drum uses a 10 bolt pattern with an 8.750/8.747 in pilot.
The hub carries the wheel and lets it rotate on the axle spindle through its bearings, with 33212 inner and 33208 outer cups and cones. A worn or loose hub shows up as wheel play, a growl from the wheel end, or heat and grease leakage at the hub. A genuine Meritor part from Pro Gear and Transmission.
