If the axle spindles already have stainless steel seal surface rings permanently installed, you do not need Spindle Seal. Service and installation instructions are included.
Spindle Seal is for use with Bearing Buddy® on trailers with brakes or as replacement seals.
The Spindle Seal System eliminates excessive grease leakage caused by rough sealing surfaces, which will quickly destroy any seal. With the Spindle Seal System, high-quality neoprene seals ride on a smooth stainless steel surface constantly greased by the action of Bearing Buddy®, which prolongs the life of the seals.
