Buying Guide
Key questions and practical guidance for selecting a boat trailer bearing kit:
- What spindle size do I have? Most kits list compatible spindles (for example 1-3/8″ to 1-1/16″ or specific L68149/L44649 bearings). Measure your spindle diameter and inner/outer bearing sizes before buying.
- Is my trailer a tapered or straight spindle? Some kits are designed specifically for tapered EZ-Lube spindles; others are not compatible with straight spindles.
- Do I need prelubricated bearings? Prelubricated kits save time and reduce installation steps, but verify that seals and dust caps match your hub.
- What other components will I need? Ensure the kit includes all required parts such as seals, dust caps, cotter pins, nuts, and washers; some kits may omit certain pieces depending on your hub.
- Are there any fitment caveats? Some kits are not compatible with straight spindles or non-round washers; double-check the spindle type and washer design.
- How many axles am I servicing? Dual-axle kits can be convenient but verify that you receive two complete bearing sets with correct seals and dust caps for both sides.
Installation tips
- Maintain cleanliness: keep all components free from dirt during installation to prevent contamination of bearings.
- Use proper equipment: a rubber mallet or soft-faced hammer helps install dust caps without damaging them.
- Proper torque: follow hub and spindle manufacturer guidelines for nut torque to avoid over-compression of bearings.
