Dexter 2,000–2,200 lb trailer axles use compact serviceable hubs with separate bearings, seals and dust caps. Depending on the original spindle, the hub may have a conventional solid grease cap or an E-Z Lube cap with a removable rubber plug. These parts are not necessarily interchangeable. Use the axle identification and the existing bearing and seal numbers to select the right replacements.

Dexter 440 / 545 hub-group parts diagram
The Dexter light-duty parts catalog includes a numbered illustration titled “440 and 545 Hub Group”, under the 1,000–2,200 lb capacity heading (printed page 12). It identifies each bearing, race, seal, spindle fastener and cap in its assembled position. The reference numbers below follow that drawing.

Conventional grease seal or E-Z Lube seal?
A standard-grease hub uses the 010-009-00 seal. The matching E-Z Lube 2K hub uses the 010-060-00 double-lip seal. Both are listed by Dexter with a 1½-inch sealing diameter, but they have different service numbers and intended spindle arrangements. Match the original seal style and journal before ordering.
Check the bearing and race markings
In the illustrated 440/545 hub group, the 031-031-02 L44649 bearing cone appears at both inner and outer positions, with an L44610 bearing cup (031-031-01) at each position. The cones and cups are separate components. Dexter also specifies L44643 bearing versions for some 2K hubs with different spindle dimensions, so capacity alone is not sufficient to choose the bearings. Compare the original stamped numbers.
Choose the correct dust cap and plug
The standard-grease hub uses a solid 021-003-00 dust cap. The 021-041-01 E-Z Lube metal cap has a centre opening for the 085-001-00 rubber plug. If replacing the cap, check the hub's diameter and whether its spindle has an E-Z Lube grease fitting.
5-on-4½-inch hubs for different wheel sizes
Dexter also distinguishes its 2K five-lug hubs by the intended wheel diameter. The factory kit table below identifies different hub castings for 8–12-inch wheels and 13–15-inch wheels; all four examples use a 5-on-4½-inch bolt circle and ½-inch wheel studs. Choose the correct hub profile as well as the right lubrication style.
| Dexter kit | Lubrication | Wheel size | Hub | Seal | Cap |
|---|---|---|---|---|---|
| K08-259-91 | Standard grease | 8–12-inch wheels | 008-259-05 | 010-009-00 | 021-003-00 |
| K08-259-92 | E-Z Lube | 8–12-inch wheels | 008-259-10 | 010-060-00 | 021-041-01 |
| K08-258-91 | Standard grease | 13–15-inch wheels | 008-258-05 | 010-009-00 | 021-003-00 |
| K08-258-92 | E-Z Lube | 13–15-inch wheels | 008-258-10 | 010-060-00 | 021-041-01 |

Spindle-nut hardware and maintenance
Dexter’s early E-Z Lube spindle arrangements used different washers from the later versions. A tang washer, nut retainer and jam nut are not interchangeable without checking the actual spindle design. Follow Dexter’s instructions for bearing adjustment and grease application, inspect the cups and cones together, and replace a removed seal as required during hub service.
Other Dexter hub and brake guides
For the next axle size, see the Dexter 3,500 lb hub guide. The 5,200–6,000 lb hub guide and 7,000 lb 865 hub guide cover different bearings and seals. Do not select wheel-end parts from another axle group by their appearance alone.
