Frequently Asked Questions

• What are Trailer Wheel Bearing Kits with Seals and Dust Caps used for? These trailer wheel bearing kits are designed to replace worn trailer hub bearings and related hardware. Each kit uses precision tapered roller bearings and is available for specific straight or stepped trailer spindle configurations. Select the appropriate kit by comparing your spindle diameter, hub bore, and existing bearing numbers with the application chart.
• What is included in the trailer wheel bearing kits? The kits include two bearing cones, two bearing cups, a grease seal, and a cotter pin. A dust cap is also included with applicable kits. The specific bearing and cup combination depends on the trailer spindle configuration and kit selected.
• How do I determine which trailer wheel bearing kit fits my trailer? Compare your existing bearing and cup numbers with the application chart rather than relying on spindle measurements alone. The chart identifies each kit by spindle type, Dexter and Tie Down part numbers, spindle diameter, hub bore, and outer and inner bearing cone and cup numbers.
• Are these trailer wheel bearing kits compatible with straight and stepped spindles? Yes. The application chart includes kits for both straight and stepped trailer spindles. Available configurations include straight spindles with diameters from 1 inch to 1-3/8 inches, as well as stepped spindle configurations. Match your existing bearing numbers and dimensions to the chart before ordering.
• What bearing numbers are available for these trailer wheel bearing kits? The available bearing combinations include L44643/L44610, LM67048/LM67010, L44649/L44610, LM11949/LM11910 with LM67048/LM67010, L44649/L44610 with L68149/L68111, and LM11949/LM11910 with L44649/L44610. The correct combination depends on the specific kit and spindle configuration.
• Why should I compare my existing bearing and cup numbers before ordering? Trailer spindle measurements alone may not confirm fitment. The product information specifically recommends comparing the bearing and cup numbers stamped on your existing components with the application chart. This helps identify the appropriate kit based on the actual bearing and cup combination used by your trailer hub.
