HELP. I'am replacing the pads and shoes and decided to remove the 4 bolts that hold the axle in place. On pulling the left side axle a spacer shaped like a half moon to fell out. Does anyone have a diagram on the rear axle assembly. I seem to be having great trouble trying to find info on the axle, differential, and generally anything to do with Lehman. Is there a specific site I'am not aware of? Any help will be greatly appreciated. The closest Lehman dealer to me is 500 km away.
