COMES SOUND FROM THE PROPELLER SHAFT DURING RUNNING THE VEHICLE '

All about engine:yes today we can discuse why comes the sound from propeller shaft during running 🏃 the vehicle. So we can get some reason about sound of propeller shaft. So if the flanz bolt 🔩 has been loose of the universal joint. So there is a possibility to comes sound from propeller shaft. And second maybe it might be the more free play are formate because of the niddle bearing friction of the universal joint. Or the free play are formate via friction of spline sleep joint. And the major thing is the both yok would be change if there more then 05.mm free play have been formate :and also comes sound if there loose foundation on the bearing brackets and bolt 🔩. And also a reason for sound like unhappy 😒 lubrication on the propeller shaft bearing and I take it like the propeller shaft has been bend.
