Advice on replacement of axle-shaft oil seal on 53 Chevy 1/2 ton. Has anyone had experience with this removal/replacement? I detected a likely oil leak on rear tire of the 53 Chevy truck and don't know what to do. The Chevy Truck manual I have is a 1948-51 Shop manual and in material on Rear Axle problems it says for removal of brake drum from axle shaft "On (1948-50) Models, install wheel cylinder clamp, KMO-145, on brake cylinder." it then goes on but I don't know what to do with the 1953 model. Also on instructions for removal of wheel and axle shafts, it goeson to say: "insert special bearing puller J-1436 and remove bearing retainer and oil seal."
Does anyone know what these tools are OR what I need to do to be able to replace the seal? I will appreciate guidance and/or where I can find replacement info on line or easily accessible. Thanks for your assistance. Jim G
