I have a 2001 Ranger and there was a Service Bulletin about this many years ago. As I recall people were complaining about a popping noise. It was discovered that the splines in the slip yoke and the splines on the output shaft were binding and as the slip yoke moved in and out as the rear suspension moved up and down this popping noise was created. The SB called for removing the driveshaft and greasing the splines with CV joint grease.
