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
- 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. - 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. - 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. - 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. - Is pre-assembly important for installation speed?

Return or exchange with correct spindle type (tapered vs. straight) and bolt pattern verified.
