How to Use Bearing Pullers
Bearing pullers are specialized mechanical tools that pull the bearings off of axle shafts. Although there are many different types and designs, they all work on the same principle. A set of jaws will hook onto the outer sides of a bearing lining or bearing case. Bearing pullers with jaws that hook onto the inside of a bearing lining are called a "blind-hole bearing puller." A central bolt or a slide hammer is then used to put reverse pressure onto the jaws that grip the bearing lining until it comes off and away from the axle.
