How to Remove a Thrust Bearing

Ball Bearings , Special Bearings , Pulley bearings

A thrust bearing is an axle located inside an engine that rotates on its axis when force is applied on it. The bearing works to reduce friction by absorbing the large amount of thrust that is produced on the engine shaft that it supports. This ensures that the engine runs smoothly and quietly. Having a thrust bearing that works properly is important for the health of the engine. If it becomes necessary for you to replace a thrust bearing in your vehicle, it will require several hours of your time as a number of engine parts will need to be moved out of the way before you can access the bearing.
