If so where is the vent located. | | | | | Joined: Feb 2016 Posts: 1,994 'Bolter | | 'Bolter Joined: Feb 2016 Posts: 1,994 | As far as I know every axle has an atmospheric vent, all of my GM rears have been on the drivers side axle tube or high on the center section. The vent on my '57 two ton is a short stub of pipe with a type of cap to prevent dirt from entering.
