Buying Guide
- What axle size do you have? Most kits cover 1-1/16″ to 1-3/8″ and 5 on 4.5″ patterns. Confirm inner and outer bearing sizes before buying.
- Spindle type matters. Some kits are designed for tapered spindles (#84) and EZ-Lube systems. Do not use on straight spindles if not specified.
- Kit contents vary. Look for full sets with bearings, races, seals, dust caps, cotter pins, and spindle nuts for a complete replacement.
- Lubrication status. Some kits are pre-lubricated; others require grease before installation. Consider maintenance needs when choosing.
- Installation complexity. All-in-one kits are convenient; mixed-size kits require careful matching to avoid misfit.
- Durability and noise. Chrome steel bearings with precise tolerances reduce vibration and improve performance on long trips.
FAQ
- Q: How do I know which bearing kit fits my trailer? A: Check your spindle size, bolt pattern (e.g., 5 on 4.5″), and whether your axle uses tapered or straight spindles. Compare with kit specifications before purchase.
- Q: Are pre-lubricated bearings ready to install? A: Some kits are pre-lubricated; others require you to apply grease. Follow the kit instructions for proper lubrication.
