Buying Guide: How To Choose The Right Pre Greased Trailer Hubs
- Spindle type: Most 5-on-4.5″ hubs are designed for tapered spindles (1-1/16″ to 1-3/8″). Do not use on straight spindles unless specified.
- Bearing compatibility: Confirm outer/inner bearing models (e.g., L44649 and L68149) match your axle data.
- Load rating: Ensure the hub kit’s 3500 lb or 2000 lb rating aligns with your trailer axle capacity.
- Lubrication status: Pre-lubricated hubs save time but verify grease seals and caps to prevent leaks.
- Corrosion resistance: Galvanized hubs offer better rust resistance for boats and saltwater environments.
- Bolt pattern and measurements: Use the outermost-to-center hole measurement for the 5-lug pattern; typical is 4.5″ on these kits.
- Installation scope: Some kits include all accessories (nuts, cotter pins, seals). Choose complete kits for faster setup.
- Packaging and shipping: For fragile components, consider packaging integrity to avoid cosmetic or internal damage during transit.
