You can see from the Witness Mark's, the area where the Bearings Pressed onto the Input Shaft. These are supposed to be a "Tight" Slip Fit! I check each and every Input Shaft O.D. with a Micrometer. Then I inspect each Inner Bore Diameter with a Bore Guage and Concentricity Guage. You will notice the old Bearings did not "Spin" on the Input Shaft
