What to Compare Before Buying
- Axle application: Verify that the trailer uses a 2,000 lb axle. This does not establish compatibility with every trailer or determine the rating of other components.
- Bolt pattern: Match the five-lug, 5-on-4.5-in pattern to the wheel.
- Spindle and bearing fit: Identify the straight spindle diameter and confirm the corresponding bearing fits the hub and spindle.
- Seal and hardware: Check the required grease seal and lug-nut thread for the specific trailer. Do not assume the listed 1/2-in-20 lug nuts fit other thread sizes.
Compatibility, Size and Fit
This kit is specified for straight spindles, not other spindle types. The two bearing sizes correspond to different spindle diameters, so confirm the actual spindle size and required bearing. A matching wheel bolt pattern alone does not confirm complete fit; also check the axle application, seal and other hub requirements.
What Is Included
The listing describes galvanized five-lug hubs, bearings for the 1-in and 1-1/16-in spindle options, grease seals, 1/2-in-20 lug nuts and dust caps. The quantity of each component is not established. Confirm the exact package contents and quantities for the repair you are planning.
Before You Decide
Check the axle application, straight-spindle diameter, bearing fit, wheel bolt pattern and grease seal requirements. Confirm the package quantities and lug-nut thread, and follow the trailer and component manufacturers’ instructions for repair and installation.
