Buying Guide: Key Considerations For 5×4.5″ Trailer Hubs
- Spindle type: Most 5×4.5″ hubs are designed for #84 tapered spindles (1-1/16″ to 1-3/8″). Do not use on straight spindles unless specified.
- Bearing compatibility: Confirm inner and outer bearings (commonly L68149 and L44649) match your axle model to avoid installation issues.
- Galvanization: Hot-dip galvanized hubs offer superior corrosion resistance in wet or saltwater conditions compared with painted finishes.
- Pre-assembly and lubrication: Pre-installed bearings and seals save time and tools; verify that the kit includes grease seals and caps to prevent leaks.
- Packaging and transport: Some sets are packaged to reduce damage during shipping; this helps maintain hub integrity in transit.
- Brand and compatibility: While many brands offer similar hub kits, verify compatibility with your axle manufacturer (Dexter, AL-KO, Lippert, etc.) when applicable.
