3mirrors Wheel Bearing Greaser Tools 35MM & 40MM & 44MM Compatible with Most Polaris ATV UTV Sportsman Ranger RZR

Wheel Bearing plays an important role in increasing engine power, but UTV and ATV bearings constantly fail due to water, dirt, sand, and lack of grease. These tools will replenish the grease your bearings need and push out contaminants. Insert the tool into your bearing and pump grease through the Zerk fitting with your grease gun. Double O-Ring seal to keep the grease inside of your bearings. O-ring seals also spread the inner bearing races apart to allow a gap for the grease to easily flow inside.
