The Chevrolet Astro Pilot Bearing maintains precise alignment of the input shaft of the manual transmission with the crankshaft, thereby ensuring smooth power transfer during gear changes. This small object, discovered either pressed into the crankshaft snout or centered in the flywheel, reduces friction by offering a low resistance surface on which the shaft can spin, thereby limiting heat buildup and gear clash. Early Chevrolet vans relied on a sintered bronze pilot bushing that runs on an oil film, while the later tendency was for an Astro Pilot Bearing that runs on miniature balls or needles between inner and outer races. The bronze type is basic and self-lubricated, but it can wear out more quickly and transfer more noise. The rolling Pilot Bearing works better at high shaft speed and handles mixed radial and axial loads with less drag. Your Chevrolet may use one of two styles of Pilot Bearing, but a quiet drivetrain depends on that bearing being free of score marks, looseness, or metal chips showing its failure. The Pilot Bearing needs immediate attention if Astro drivers notice chirps at idle, shakes when the clutch is engaged, or if a gear refuses to shift.
