Frequently Asked Questions
- What is a 4 lug trailer hub kit best for? It’s ideal for trailers with 4-lug wheels and 2000 lb axles, offering ready-to-install bearings, seals, and mounting hardware.
- How do I know if my axle uses a straight or tapered spindle? Measure the spindle diameter along the shaft and confirm if it tapers toward the wheel; straight spindles remain constant in diameter.
- Are two different bearing sizes included in these kits common? Yes, some kits include both L44643 and L44649 bearings to cover 1″ and 1-1/16″ straight spindles.
- Can I reuse my existing lug nuts with a new hub kit? It depends on the kit; many include new lug nuts, but you should verify compatibility with your wheel’s lug nut seats and thread size.
- What should I do if I notice leaks after installation? Recheck the grease seals, verify the seal size matches your spindle, and ensure the hub is seated properly against the spindle shoulder.
- Is pre-lubricated better? Pre-lubricated bearings simplify installation and improve initial performance, but you should still inspect seals and lubricity after installation.
