Buying Guide
Key questions to consider when choosing trailer hubs for 5-lug axles:
- What spindle type does your trailer use? Straight vs. tapered spindles require different hub designs and bearings.
- What load rating do you need? Choose hub kits rated for the trailer’s gross weight and axle capacity to avoid premature wear.
- Are bearings pre-installed? Pre-installed bearings save time and reduce installation error, but verify compatibility with your axle size.
- Is the hub kit compatible with your axle brand? Popular brands include Dexter, Al-Ko, Lippert, and Quality; confirm outer/inner bearing sizes.
- What about corrosion resistance? Freshwater exposure and humidity call for durable coatings and corrosion-resistant steel.
- Can you source complete kits? Some sets include seals, races, and hardware; others require separate purchases for a full replacement.
Installation and maintenance tips
- Follow manufacturer torque specs when reassembling. Over-tightening can cause bearing failure.
- Use marine-grade grease and inspect seals for leaks during routine trailer maintenance.
- Check wheel bearings for play and smooth rotation after install.
