In this video we go over replacing a leaking NOS GM pinion flange oil seal on a 1957 Chevrolet BelAir with the 3:36 positraction rear axle. We cover the vintage technical service bulletin information and install a later generation NOS GM pinion flange oil seal. While the technical information is 1957 model year specific, the tools and approach shown in this video apply to any Chevy passenger car model from 1955 thru 1964. Once I did this the leak stopped, and has stopped for well over a month now.
