For Dexter's 7,000 lb 865 trailer axle hub-and-drum assembly, the correct wheel bearings are 25580 inner and 14125A outer. The E-Z Lube version also uses a specified grease seal, cap and removable rubber plug. This guide brings together those factory part numbers and the corresponding items available from UsedRVParts.

The hub shown here is the 008-219-13, with an 8-on-6½-inch wheel bolt pattern and 9/16-inch wheel studs. Check the hub number, stud size, grease-seal journal and existing bearings before ordering: other 7,000 lb hub versions use different studs, seals or lubrication arrangements.

Match both bearings and their cups

On the 865 hub, 25580 is the inner bearing cone and 25520 its matching cup. The outer bearing cone is 14125A, paired with a 14276 cup. All four numbers must be correct. A bearing cone alone does not include its cup.

The Lippert 2023133983 bearing kit lists this 25580/25520 and 14125A/14276 combination for a matching 7,000 lb hub. Its included installation hardware should be checked against the spindle and retaining arrangement already fitted to your trailer.

Grease seal, cap and plug

The 010-036-00 is Dexter's 2¼-inch-inside-diameter E-Z Lube grease seal for this hub arrangement. The correct grease cap is 021-043-01; the 085-001-00 rubber plug fits the centre opening. A similar cap for a different hub series is not automatically a substitute.

Dexter also offered the 7,000 lb hub-and-drum in different stud and seal configurations. The 008-219-13 is identified as a cupped-and-studded hub/drum, while the K08-219-9C factory kit contains additional service components. See Dexter's complete hub-and-drum kit list (PDF) for the included parts.

Related 7,000 lb trailer brake assemblies

If you are also servicing the wheel's electric brake, these are separate left- and right-hand 12 × 2-inch Nev-R-Adjust assemblies. They are not included with the bearing service components above.

Before refitting a hub

Inspect the seal contact surface, both bearing cups, the brake drum and the spindle for wear. Replace a damaged seal during bearing service, and follow Dexter's specified bearing adjustment, grease and wheel-nut torque procedures. Do not overfill the E-Z Lube system; grease leaking into a brake can reduce braking performance.

For other axle families, see the 3,500 lb E-Z Lube hub guide and 5,200–6,000 lb hub bearing guide. For additional 12-inch brake components, see the Dexter electric brake parts diagram.
