That could be easily cause by an input or output shaft somewhere that has gotten slightly bent. Any time there is a drive-line/u-joint failure and the drive shaft hits the frame real hard, This can happen. Chocking the wheels, Jacking up the rear so that the tires can spin freely (and doing it in a safe manner)... and then putting it in gear .. checking for any of the input or output shafts for a slight "stir" to them it while rotating will usually reveal a bend shaft that might be causing repeated u-joint and other failures.
