1963 Chevrolet Biscayne Positraction Differential Overhaul - Part 3.1 - Repaired

Weber State University (WSU) - Automotive Technology Department - Transmission Lab. We take on a fun and unusual project, the overhaul and restoration of the rear differential of a 1963 Chevrolet Biscayne. This 8.2" type 3 differential was used by General Motors from 1955-1964. The differential design utilizes threaded adjustable side bearing spacers to control side bearing preload and backlash.

This video shows the process we used to repair excessive lateral runout in the differential case of this car with a bench Brake Lathe!
