Buying Guide
Key purchase considerations:
- Spindle compatibility: Confirm whether your axle uses tapered (1-1/16″ to 1-3/8″) EZ-Lube spindles or straight spindles, as most kits in this group target tapered spindles.
- Bearing sizes: Verify L44649 outer and L68149 inner bearings, or the equivalents listed, to avoid fit issues.
- Bolt pattern: Most hubs use a 5×4.5″ bolt pattern. Measure from the outer edge to the center of the opposite hole to confirm.
- Material and finish: Galvanized hubs resist corrosion better in salty or humid environments, while non-galvanized hubs may be suitable for inland use.
- Pre-assembly and lubrication: Pre-lubricated hubs reduce installation steps and downtime, but ensure seals are intact and correctly seated during install.
- Accessories included: Check if the kit provides all necessary parts (grease seals, nuts, cotter pins, washers, lug nuts) for installation.
