The only thing worse than doing a boat trailer bearing replacement is not doing a bearing replacement and then getting caught out along the interstate with a broken-down rig. Hunting for a set of bearings at 5 a.m. is a fruitless enterprise, I can report from sad experience.
This universal trailer axle bearing replacement kit can be used in 3,500- to 7,000-pound capacity Lippert Components, Dexter or Al-Ko axles including one Outer Bearing L44649, one Inner Bearing L68149, one Inner Cup L68111, one Outer Cup L44610, one Grease Seal and cotter pin. Be sure to inspect and maintain your trailer axle bearings periodically for safety and best performance. Worn-out bearings can lead to axle failure.
