Buying Guide
What matters most: correct bolt pattern, spindle type, and bearing sizes. Always measure or verify:
- Bolt pattern: 5 lug, 4.5″ diameter is common for 3500lb axles.
- Spindle type: tapered (#84) vs straight spindles; only tapered spindles are compatible with these kits.
- Bearings: ensure the I.D. of outer and inner bearings match your axle’s bearings (L44649 and L68149 are common pairings).
- Included hardware: lug nuts, caps, seals, and cotter pins can save you trips to the hardware store.
How to compare:
- Best for all-in-one convenience: look for kits that include two complete hub assemblies and all hardware in one box.
- Better for spare parts: choose kits that include extra caps, seals, and plugs to cover maintenance needs.
- Choose this if you upgrade to a different bolt pattern in the future: confirm that the kit’s bolt pattern matches your trailer’s existing tires and wheels.
