Trailer bearing kits should be matched by the bearing numbers, race numbers, grease seal size, and axle hub application — not axle capacity alone. Before ordering, compare your existing inner bearing, outer bearing, races, grease seal, hub, and spindle measurements to the kit specifications.
LM67048 is the outer bearing cone number. The matching outer race cup is LM67010. The inner bearing cone is 25580, and the matching inner race cup is 25520.
1. Confirm Fit: Match the existing bearing numbers, race numbers, grease seal size, hub, and spindle before replacement. 2. Remove Hub: Safely lift and support the trailer, remove the wheel, dust cap, cotter pin, spindle nut, washer, and hub assembly. 3. Replace Components: Remove old bearings, races, and grease seal, then install the new races, packed bearings, and seal. 4. Reassemble Hub: Reinstall the hub with the spindle washer, spindle nut, and cotter pin according to axle manufacturer service procedures. 5. Check Operation: Verify proper bearing preload, smooth hub rotation, grease level, and wheel installation before towing. Trailer hub service should be performed by a qualified technician if bearing preload, race installation, or hub service procedures are uncertain.
