38505 - BEARING BUDDY II WITH BRA

The ultimate bearing protector with the added feature of "Auto Check: Visual Lubricant and Pressure Indicator". This updated version of Bearing Buddy has a spring loaded piston behind the Auto Check ring that pushes against the grease which generates pressure inside the hub to keep water out. If the lubricant is low, the blue Auto Check ring will recede until it is flush with the steel-retaining ring. Add a small amount of grease to move the blue ring outward about 1/8". It's that simple! Fits outer bearing cone numbers: L44643, L44649, and L44640. 1.980 Dia.
