I have a 1972 Bronco with "posi-traction" rear end. It is making a banging noise about every 5-8 feet around a corner . I disconnected the drive shaft and drove it with the front end and it still made the noise. Eliminating the U Joints. Was told perhaps needs additive added to the differiential oil. Where is the drain plug where I can put this in and your thoughts about the noise.
