Bearing Buddy (42441 Bra

Towing causes trailer wheel hubs to heat up; submersion during launching quickly cools them, forming a vacuum which sucks in water and can cause damage. The Bearing Buddy provides permanent wheel bearing protection and lubrication for all types of trailers. Water and dirt are kept out of the hub. Lubricant level can be quickly and easily checked by pressing on piston. Quality construction features stainless steel internal parts, and a triple chrome-plated barrel. Won't crack or pop out. You can totally submerge wheels and float a boat on or off the trailer. (Pair). Outer Baring cone number LM67048, hub counter bored.
