I’m starting to assemble my ‘57 1/2 ton NAPCO project and I can’t remember what was originally going on with the rear axle. I have a bearing, a seal, and what looks like a shim. When I look at the factory service manual, I don’t see the shim. Does anyone know where that shim goes and why it’s there?
Here’s what I have. I think I understand how to assemble it now after rereading the manual. The part I’m really unsure about is the gasket between the oil slinger on the axle flange and the flange itself. Do I need to take that apart and replace the gasket if I don’t see any oil on the inside surface of the flange?
