Overview
This bearing kit is designed for servicing compatible 3,500 lb Lippert trailer axle hubs. The kit includes the inner and outer bearings, matching races, grease seal, tang washer, and cotter pin used during a standard hub bearing service. Because trailer axle parts are application-specific, confirm the bearing numbers, race numbers, seal number, and axle manufacturer before installation.
R&P Service Insight
Do not rely on axle capacity alone when selecting a bearing kit. Two axles with the same listed capacity can use different bearing and seal combinations depending on manufacturer, hub style, spindle, and production series.
- Best Check: Match the numbers stamped on your existing bearings and races.
- Seal Check: Confirm the grease seal number or dimensions before ordering.
- Manufacturer Check: This listing is for Lippert 3,500 lb axle applications and is not for Dexter D44 axles.
R&P Knowledge Hub
Compatibility: Intended for compatible 3,500 lb Lippert trailer axle hubs using L44649 outer bearing, L68149 inner bearing, L44610 outer race, L68111 inner race, and 171255TB grease seal.
Vehicle / System Fit: Trailer hub bearing service for matching Lippert axle applications.
Installation Notes: Inspect spindle condition, hub bore, races, seal surface, and grease condition before reassembly. Replace damaged or pitted parts rather than reusing worn components.
Performance Insight: Correct bearing and seal matching helps support proper hub rotation, grease retention, and service reliability.
Brand & Fitment Note
Selling Brand: R&P Carriages bearing service kit for listed Lippert axle applications.
Application Reference: Lippert is used as an axle application reference for fitment. This kit should be matched by bearing, race, seal, and axle manufacturer before ordering.
What This Means: This listing is for a bearing service kit for compatible Lippert 3,500 lb axle applications, not a guaranteed OEM-branded Lippert item unless specifically stated on the product packaging.
Before Ordering: Verify axle manufacturer, bearing numbers, race numbers, grease seal number, hub style, spindle condition, and included components before installation.
R&P Repair Insight
When servicing trailer hubs, confirm the fit before packing bearings or installing races. Bearing kits are not universal across all 3,500 lb axles.
- Bearing Match: Confirm L44649 and L68149 are the correct bearing numbers for your hub.
- Race Match: Confirm L44610 and L68111 match your existing races.
- Seal Match: Confirm 171255TB matches your existing grease seal or seal dimensions.
