The pilot bearing is one of the main components that connects the manual transmission input shaft to the engine crankshaft. This bearing allows the input shaft to rotate independently of the crankshaft. The pilot bearing lies between the crankshaft and the flywheel, after which it is followed by clutch disc, pressure plate, and input shaft. The integrity of the entire clutch system engaging with the crankshaft hinges on the bearings and all the other working parts functioning correctly.
There are some symptoms that can indicate the pilot bearing needs replacement. An abnormal noise each time the clutch pedal is depressed, or it being difficult to shift gears due to clutch drag, which is when the input shaft continues to spin slowly when the clutch pedal is depressed. The ideal time to replace the pilot bearing is when the clutch is being replaced. When the replacement of the clutch takes place, it is important to use a clutch alignment tool, or you may do damage to the pilot bearing when replacing the transmission in the vehicle. That said this is a procedure which should be handled by a seasoned professional.
