Buying Guide

What should I check before buying a 3,500-lb trailer hub kit?

  • Spindle compatibility: Confirm whether your trailer uses tapered (1-1/16″ to 1-3/8″ #84) vs. straight spindles. Match the kit’s bearings (L68149/L44649) to your axle.
  • Bolt pattern: Ensure the hub kit’s bolt pattern (e.g., 5×4.5″ or 5×5″) matches your wheel.
  • EZ-Lube compatibility: If your trailer uses EZ-Lube axles, choose kits explicitly listing EZ-Lube compatibility.
  • Included hardware: Look for kits that include bearings, races, seals, caps, lug nuts, and bolts to avoid buying parts separately.
  • Pre-greased vs. pre-assembled: Pre-greased kits save installation time; pre-assembled bearings minimize on-site work.
  • Environmental conditions: Rust-resistant finishes are beneficial for boat trailers or saltwater use.

FAQ

  1. What does 3,500 lb hub capacity mean for me?
    It indicates the axle’s safe working load; ensure your entire trailer axle and frame support that rating.
  2. Do these kits fit EZ-Lube axles?
    Some kits are listed as EZ-Lube compatible; verify product notes and confirm compatibility with your axle type.
  3. How do I know which bearing numbers I have?
    Check your current bearings for part numbers L68149 (inner) and L44649 (outer) to match kit components.
  4. Can I mix hubs from different brands?
    It’s best to use identical bolt patterns and bearing sizes; mixing may cause wheel misalignment or improper fit.
  5. Is pre-assembly important for installation speed?
    Yes. Pre-assembled hubs reduce handling and installation time on the trailer.
  6. What if the hub kit doesn’t fit my spindle?
    Return or exchange with correct spindle type (tapered vs. straight) and bolt pattern verified.
