I am new to the forum but have LOVED my 61 Econoline p/u for several years. It has been a great, good-looking daily driver and I have even used it often to move furniture and stuff for myself and for friends. Unfortunately the rear end is now apparently shot. It leaks like crazy and shudders so bad upon stopping that I have had to quit driving the truck. A local mechanic who specializes in antiques and is usually pretty good says the rear end cannot be repaired and must be replaced. Is he right? If so, are direct replacements available? If not, what else might work? I have heard that a Ford 9" will work and wrote to Jimbare about it, but I know he's busy. I have also heard that a late-model Ranger rear end can be used. I need ideas. Can you all help me out?
