Dexter Vault Service Kit K71-030-00 for 2500, 3200, 3500 lb 545 Series Trailer Axles, 1.980 Inch Bore

The Dexter Vault Service Kit, part number K71-030-00, is a complete rebuild and maintenance kit for the Dexter Vault bearing protector system used on 2500, 3200, and 3500 lb capacity 545 series trailer axles with a 1.980 inch outer bore. Rather than sourcing individual seals and hardware separately, this kit bundles everything needed to service a pair of hubs in one package: two O-rings, a matched pair of Trailer Buddy assemblies, a vault lube tube, a dedicated vault installation tool, loctite for securing hardware during reassembly, and a grease fitting. The kit is packaged as a single unit (package quantity of 1) and is intended for trailer owners and service shops performing routine bearing protector maintenance or replacing worn Vault components on Dexter-equipped axles. Using the correct outer bore size and axle capacity ensures the Trailer Buddy assemblies and O-rings seat properly, keeping the bearing protector sealed against water and debris intrusion. The included installation tool is sized specifically for the Vault system, helping ensure the assemblies are seated to the correct depth without damaging the O-ring seals. At 2.2 pounds, the kit is compact enough for on-trailer service or storage in a tow vehicle for roadside maintenance.
