The Stovebolt Site Forums The Shop Area Driveline Axle shim at outer wheel bearing

There is a washer that is installed prior to the bearing. There is a shoulder in the axle housing that this washer sits on. My guess is it’s there to prevent the bearing from being pushed in when you install the axle. I have them in mine and I made a drawing of that whole assembly when I machined my axles to install ‘37 Buick inner bearing sleeves which match the OD of the original axle effectively creating a new surface for the bearing and seal to ride on. Here is that drawing with the washer highlighted in red.
