Dexter Bearing and Seal Replacement Kit K71-059-00, 545 Bearing, 1.980 Inch Outer Bore, 3.2K and 3.7K Axles, 1 Axle Set

The Dexter K71-059-00 Bearing and Seal Replacement Kit supplies the bearings and seal needed to service one boat trailer axle rated for 3.2K and 3.7K applications. It is built around the 545 bearing with a 1.980 inch outer bore, matching the hub dimensions used on these axle capacities. This kit is intended for routine maintenance and repair when hub bearings show wear, run dry of grease, or fail an inspection, and it lets the owner replace the wearing components without buying a full hub assembly.

Because trailer bearings operate submerged and reheated with every launch and retrieval cycle, using a matched bearing and seal set from Dexter helps maintain the correct fit and seal engagement that a hub depends on for water resistance. Each kit is packaged to service a single axle; a trailer with two axles will require two kits, and tandem or triple-axle trailers should order a kit per axle serviced.
